162-554: M-8 is a 5.5-mile (8.9 km) state trunkline highway in the U.S. state of Michigan lying within the cities of Detroit and Highland Park . Much of it is the Davison Freeway , the nation's first urban depressed freeway, which became a connector between the Lodge ( M-10 ) and the Chrysler ( Interstate 75 , I-75) freeways. Named for an English immigrant to the area, Davison Avenue
324-522: A concurrency or overlap. For example, I‑75 and I‑85 share the same roadway in Atlanta ; this 7.4-mile (11.9 km) section, called the Downtown Connector , is labeled both I‑75 and I‑85. Concurrencies between Interstate and US Highway numbers are also allowed in accordance with AASHTO policy, as long as the length of the concurrency is reasonable. In rare instances, two highway designations sharing
486-589: A 1957 state law, the department sold $ 700 million in bonds (equivalent to $ 5.81 billion in 2023 ) in the late 1950s and early 1960s to finance land purchases and construction of the new freeways. The first Interstate Highway in the state was signposted in October 1959 when I-75 signs were first installed along the Detroit–Toledo Expressway. These signs replaced US 24A signage in the Monroe area, after
648-637: A 28-year-old brevet lieutenant colonel, accompanied the trip "through darkest America with truck and tank," as he later described it. Some roads in the West were a "succession of dust, ruts, pits, and holes." As the landmark 1916 law expired, new legislation was passed—the Federal Aid Highway Act of 1921 (Phipps Act). This new road construction initiative once again provided for federal matching funds for road construction and improvement, $ 75 million allocated annually. Moreover, this new legislation for

The entire highway is in Wayne County . All exits are unnumbered. Michigan State Trunkline Highway System The State Trunkline Highway System consists of all
972-476: A change in the numbering system as a result of a new policy adopted in 1973. Previously, letter-suffixed numbers were used for long spurs off primary routes; for example, western I‑84 was I‑80N, as it went north from I‑80 . The new policy stated, "No new divided numbers (such as I-35W and I-35E , etc.) shall be adopted." The new policy also recommended that existing divided numbers be eliminated as quickly as possible; however, an I-35W and I-35E still exist in
1134-517: A dedication ceremony at 4:00 p.m. on November 25, 1942. Travel times across Highland Park dropped from 15 minutes to around 3–4 minutes after the freeway opened. The roadway was the first urban, depressed freeway in the United States. The concrete for the road bed was cured underwater by flooding, creating an extremely hard and durable surface which lasted for more than 50 years (some requiring dynamite for its eventual removal). In 1968,
1296-414: A distance of 220 miles (350 km) from Zilwaukee to Mackinaw City by way of Traverse City ; the shortest was a mile (1.6 km) near Sault Ste. Marie . Townships continued to maintain and build local roads using the "statute labor system". An able-bodied man residing in a local road district was expected to pay his road taxes by performing 30 days of labor on the roads in his district. If he
1458-418: A half-block of right-of-way on the south side of Davison Avenue and the demolition of 69 homes to accommodate the 12–17 feet (3.7–5.2 m) of excavation along the 1.3-mile (2.1 km) project. Another 63 homes were moved. The outbreak of World War II accelerated the construction schedule after the project was given priority due to the defense plants near the roadway. The freeway opened for traffic without
1620-432: A mile (about 1.2 km). Some roads are unsigned highways , lacking signage to indicate their maintenance by MDOT; these may be remnants of highways that are still under state control whose designations were decommissioned or roadway segments left over from realignment projects. Predecessors to today's modern highways include the foot trails used by Native Americans in the time before European settlement. Shortly after
1782-580: A national road grid with the passage of the Federal Aid Highway Act of 1921 . In 1926, the United States Numbered Highway System was established, creating the first national road numbering system for cross-country travel. The roads were state-funded and maintained, and there were few national standards for road design. United States Numbered Highways ranged from two-lane country roads to multi-lane freeways. After Dwight D. Eisenhower became president in 1953, his administration developed
SECTION 10
#17328512973871944-502: A non-motorized road restricted to bicycles, horse-drawn carriages and pedestrians. The highest numbers used for highway designations include M-553 in the UP and Interstate 696 (I-696) running along the northern Detroit suburbs. The lowest numbers in use are M-1 along Woodward Avenue in the Detroit area and US Highway 2 (US 2) across the UP. Most M-numbered trunkline designations are in
2106-576: A numbering scheme in which primary Interstates are assigned one- or two-digit numbers, and shorter routes which branch off of longer ones are assigned three-digit numbers where the last two digits match the parent route. The Interstate Highway System is partially financed through the Highway Trust Fund , which itself is funded by a combination of a federal fuel tax and transfers from the Treasury's general fund. Though federal legislation initially banned
2268-527: A population of more than 50,000 people with a network of roads that would accommodate traffic at 70 mph (110 km/h). Following the start of these highway improvements, the MSHD adopted a policy to allow traffic to use the state's trunklines every day of the year regardless of the weather. The state also invested in improving non-freeway roads in the highway system; better materials and construction methods were used to improve safety and traffic flow throughout
2430-481: A proposal for an interstate highway system, eventually resulting in the enactment of the Federal-Aid Highway Act of 1956 . Unlike the earlier United States Numbered Highway System, the interstates were designed to be all freeways, with nationally unified standards for construction and signage. While some older freeways were adopted into the system, most of the routes were completely new. In dense urban areas,
2592-540: A report called Toll Roads and Free Roads , "the first formal description of what became the Interstate Highway System" and, in 1944, the similarly themed Interregional Highways . The Interstate Highway System gained a champion in President Dwight D. Eisenhower, who was influenced by his experiences as a young Army officer crossing the country in the 1919 Motor Transport Corps convoy that drove in part on
2754-409: A single digit prefixed to the two-digit number of its parent Interstate Highway. Spur routes deviate from their parent and do not return; these are given an odd first digit. Circumferential and radial loop routes return to the parent, and are given an even first digit. Unlike primary Interstates, three-digit Interstates are signed as either east–west or north–south, depending on the general orientation of
2916-504: A special green version of the standard Interstate marker which places the word "Business" at the top where "Interstate" would otherwise appears. These business loops and spurs connect downtown districts to main highways after realignments and bypasses have routed the main highway out of the downtown area. Another category, connector routes, serve to connect two highways as their names suggest; most of these connectors are unsigned. The highways names for special routes are formulated by prefacing
3078-769: A speed limit of 45 mph (70 km/h) because it is a parkway that consists of only one lane per side of the highway. On the other hand, Interstates 15, 80, 84, and 215 in Utah have speed limits as high as 70 mph (115 km/h) within the Wasatch Front , Cedar City , and St. George areas, and I-25 in New Mexico within the Santa Fe and Las Vegas areas along with I-20 in Texas along Odessa and Midland and I-29 in North Dakota along
3240-456: A speed limit of 80 mph (130 km/h). Other Interstates in Idaho, Montana, Oklahoma, South Dakota and Wyoming also have the same high speed limits. In some areas, speed limits on Interstates can be significantly lower in areas where they traverse significantly hazardous areas. The maximum speed limit on I-90 is 50 mph (80 km/h) in downtown Cleveland because of two sharp curves with
3402-511: A state-financed system. The system comprised 10 divisions , several of which had associated branches , that ran along existing roads throughout the state. After the creation of the system, the Huron Shore Road Association scheduled a Road Bee Day on June 13, 1913; some 5,000 men, 200 women, 3,000 teams of horses and 750 automobiles participated in the effort that improved 200 miles (320 km) of roads in
SECTION 20
#17328512973873564-465: A statute labor system that required landowners to make improvements in lieu of taxes. Countywide coordination of road planning, construction and maintenance was enacted in the late 19th century. In the early 20th century, the constitutional prohibition on state involvement in roads was removed. The Michigan State Highway Department (MSHD) was created in 1905, and the department paid counties and townships to improve roads to state standards. On May 13, 1913,
3726-467: A suggested limit of 35 mph (55 km/h) in a heavily congested area; I-70 through Wheeling, West Virginia , has a maximum speed limit of 45 mph (70 km/h) through the Wheeling Tunnel and most of downtown Wheeling; and I-68 has a maximum speed limit of 40 mph (65 km/h) through Cumberland, Maryland , because of multiple hazards including sharp curves and narrow lanes through
3888-403: A wider left shoulder for improved safety and traffic handling as well as a new interchange with Woodward Avenue . The reconstructed freeway was reopened on October 8, 1997, by Governor John Engler . In 2001, M-8 was extended to include the two-mile (3.2 km) segment of Davison Avenue between the freeway's western terminus and Davison Avenue's junction with I-96 (Jeffries Freeway). Except for

While military motivations were present, the primary motivations were civilian. The numbering scheme for the Interstate Highway System was developed in 1957 by the American Association of State Highway and Transportation Officials (AASHTO). The association's present numbering policy dates back to August 10, 1973. Within

MDOT continues to purchase parcels for right-of-way to be used for future upgrades of US 127 along the expressway section between Ithaca and St. Johns . The United States Congress legislated a highway proposal in 1991 known as I-73 . Originally set to run along I-75 to Detroit,
4374-525: Is to have the highway route extend from Tamaulipas , Mexico to Ontario , Canada. The planned I-11 will then bridge the Interstate gap between Phoenix, Arizona and Las Vegas, Nevada , and thus form part of the CANAMEX Corridor (along with I-19 , and portions of I-10 and I-15 ) between Sonora , Mexico and Alberta , Canada. Political opposition from residents canceled many freeway projects around
4536-600: The BL I-94 interchange just south of the I-196/US ;31 interchange. In the interim, MDOT built a 9.1-mile (14.6 km) freeway segment north to Napier Avenue that was opened on August 27, 2003, at a cost of $ 97 million (equivalent to $ 154 million in 2023 ). In 2020, work began on the final link to connect the US ;31 freeway to I-94 east of Benton Harbor. The project cost $ 121.5 million dollars and involved relocating
4698-474: The Dallas–Fort Worth metroplex in Texas, and an I-35W and I-35E that run through Minneapolis and Saint Paul , Minnesota, still exist. Additionally, due to Congressional requirements, three sections of I-69 in southern Texas will be divided into I-69W , I-69E , and I-69C (for Central). AASHTO policy allows dual numbering to provide continuity between major control points. This is referred to as
4860-538: The Federal Aid Highway Act of 1956 into law. Under the act, the federal government would pay for 90 percent of the cost of construction of Interstate Highways. Each Interstate Highway was required to be a freeway with at least four lanes and no at-grade crossings. The publication in 1955 of the General Location of National System of Interstate Highways , informally known as the Yellow Book , mapped out what became

He recalled that, "The old convoy had started me thinking about good two-lane highways... the wisdom of broader ribbons across our land." Eisenhower also gained an appreciation of the Reichsautobahn system, the first "national" implementation of modern Germany's Autobahn network, as a necessary component of a national defense system while he
5670-489: The M -numbered highway designations existed on state highways throughout Michigan, while the creation of the US Highway System in 1926 caused several existing designations to be either reassigned or retired altogether. Public Act 131 of 1931 allowed the MSHD to take control over the city and village streets that carried state highways through cities and villages in the state. The 1932 McNitt Act consolidated all of
5832-607: The National Highway System , which are highways selected for their importance to the country's economy, defense, and mobility. The state trunkline highways in Michigan carry approximately 51 percent of the state's traffic, as of 2007 . The highways in the system range in length from the unsigned Business Spur Interstate 375 (BS I-375) at 0.170 miles (0.274 km) and signed M-212 at 0.732 miles (1.178 km) to I-75 at 395.40 miles (636.33 km). Some trunklines in Michigan are maintained by MDOT but bear no signage along
5994-499: The US Department of Defense . The system has also been used to facilitate evacuations in the face of hurricanes and other natural disasters. An option for maximizing traffic throughput on a highway is to reverse the flow of traffic on one side of a divider so that all lanes become outbound lanes. This procedure, known as contraflow lane reversal , has been employed several times for hurricane evacuations. After public outcry regarding

M-6 , a southern freeway bypass of Grand Rapids first proposed in the 1960s, was built between 1997 and 2004; that freeway was controversial based on the choice of a minority-owned subcontractor and route location. Bypasses of Cadillac and Manton opened in 2001 and 2003, extending

The state highway commissioner was required to sign the state trunkline highways, and Michigan became the second state after Wisconsin to do so. Alan Williams, Ionia County engineer, helped to design
7452-559: The Congress Hotel in Chicago. In the plan, Mehren proposed a 50,000-mile (80,000 km) system, consisting of five east–west routes and 10 north–south routes. The system would include two percent of all roads and would pass through every state at a cost of $ 25,000 per mile ($ 16,000/km), providing commercial as well as military transport benefits. In 1919, the US Army sent an expedition across
7614-630: The I-296 designation was "a potential source of confusion for motorists." FHWA agreed with the department's proposal to eliminate all signage and public map references to the designation in April 1979. MDOT then received permission from the American Association of State Highway and Transportation Officials (AASHTO) on October 13, and from the FHWA on December 3, 1979, on the condition that MDOT would continue to use

This announcement derailed the efforts to build the Michigan Turnpike. The Interstate Highway System was authorized by the Federal Aid Highway Act of 1956 , and the state had already designed several freeways for its portion of that system. Seizing the opportunity brought by

For fiscal year 2013, MDOT has budgeted approximately $ 1.2 billion on the highway system, including $ 273.4 million in routine maintenance. The remainder financed major projects in terms of planning, right-of-way acquisition or construction. In terms of winter maintenance, MDOT classifies all state highways into two priority levels for snow removal, authorizing overtime to clear some highways in

In the rest of the state, M-6 near Grand Rapids , Conn. M-13 near Bay City , M-47 near Midland , M-60 near Jackson , and Bus. US 131 near Kalamazoo are also freeways, for all or part of their respective lengths. Sections of US 12 , M-20 , M-37 , M-46 , M-55 , M-66 and US 223 have been routed to run concurrently with other freeways as well. As of January 2013 , there are three sources of revenue that contribute to
8910-503: The Michigan State Highway Department (MSHD), was created on July 1, 1905. At first the department administered rewards to the counties and townships for building roads to state minimum specifications. In 1905, there were 68,000 miles (110,000 km) of roads in Michigan. Of these roads, only 7,700 miles (12,000 km) were improved with gravel and 245 miles (394 km) were macadam . The state's statute labor system

In countries like the United Kingdom, M refers to motorways , analogous to freeways in the United States, whereas M -numbered designations in Michigan simply indicate state trunklines in general and may exist on any type of highway. M -numbered trunklines are designated along a variety of roads, including eight-lane freeways in urban areas, four-lane rural freeways and expressways, principal arterial highways, and two-lane highways in remote rural areas. The system also includes M-185 on Mackinac Island ,
9396-490: The State Reward Trunk Line Highways Act was passed, creating the State Trunkline Highway System. The MSHD assigned internal highway numbers to roads in the system, and in 1919, the numbers were signposted along the roads and marked on maps. The US Highway System was created in 1926, and highways in Michigan were renumbered to account for the new designations. Legislation in the 1930s consolidated control of

One almost absolute standard is the controlled access nature of the roads. With few exceptions , traffic lights (and cross traffic in general) are limited to toll booths and ramp meters (metered flow control for lane merging during rush hour ). Being freeways , Interstate Highways usually have

As of 2022 , about one quarter of all vehicle miles driven in the country used the Interstate Highway System, which has a total length of 48,890 miles (78,680 km). In 2022 and 2023,
11664-497: The construction and improvement of highways. The nation's revenue needs associated with World War I prevented any significant implementation of this policy, which expired in 1921. In December 1918, E. J. Mehren, a civil engineer and the editor of Engineering News-Record , presented his "A Suggested National Highway Policy and Plan" during a gathering of the State Highway Officials and Highway Industries Association at
11826-517: The construction of a toll freeway to run north–south in the state. The original termini for the Michigan Turnpike were Bridgeport and Rockwood . The state highway commissioner at the time, Charles Ziegler , distrusted a separate agency dealing with statewide road building at the time and worked to stall progress on any proposed turnpikes. He also opposed the idea because the state had three freeways under planning or construction. Ziegler and
11988-503: The construction of the Detroit–Fort Meigs Road to Toledo as a response to transportation needs. More roads were built with Congressional appropriations in the 1820s and 1830s connecting Detroit to Port Huron , Saginaw , Grand Rapids and Chicago . Townships were given authority to construct roads under the supervision of county commissioners in 1817. This supervision was difficult since in one case, one county covered all of
12150-407: The contiguous United States, primary Interstates—also called main line Interstates or two-digit Interstates—are assigned numbers less than 100. While numerous exceptions do exist, there is a general scheme for numbering Interstates. Primary Interstates are assigned one- or two-digit numbers, while shorter routes (such as spurs, loops, and short connecting roads) are assigned three-digit numbers where
12312-594: The creation of the Michigan Territory in 1805, the new government established the first road districts. The federal government aided in the construction of roads to connect population centers in the territory. At the time, road construction was under the control of the township and county governments. The state government was briefly involved in roads until prohibited by a new constitution in 1850. Private companies constructed plank roads and charged tolls . Local township roads were financed and constructed through
12474-415: The definition was amended in 1995 to include a branch that would run along US 223 and US 127 to Grayling , then on a continuation along I-75 to Sault Ste. Marie . MDOT examined three options to build the freeway, but abandoned further study after June 12, 2001, diverting remaining funds to improvement of safety along the corridor. The department stated there was a "lack of need" for sections of
12636-440: The department's Trunkline Numbering Committee and the district traffic and safety engineers on October 19, 1982, for proposals to reduce or eliminate the various overlapping designations to "avoid driver confusion and save funds". When the unit released its final recommendations on March 17, 1983, the memo recommended 19 changes to eliminate various concurrent routings, including the truncation of US 2 to St. Ignace , changes to
12798-486: The designation M-275 instead. Opposition to construction came from various citizen's groups, different levels of local government, and both The Detroit News and Detroit Free Press . The Detroit City Council, led by then-Chairman Carl Levin , opposed the plan as well. Levin said at the time, "At last I think people are waking up to the dangers of more and more expressways. At some point we've got to say enough. And I think we've reached it." The United States Department of
12960-482: The designation ends. Davison Avenue continues past Mound Road where it turns back due east until it ends at Van Dyke Street next to the Mt. Olivet Cemetery. MDOT's 2007 traffic surveys counted the average annual daily traffic (AADT), a measure of the number of vehicles using a section of roadway on any given day of the year. An average of 38,000 vehicles used the western section of M-8 along Davison Avenue in 2007 each day;
13122-508: The designation on official documents. The approval explicitly retained the highway in the Interstate system for funding and other purposes. The last state map to show the I-296 designation was published in 1979, as the 1980 map lacks any reference to the designation. Following this program, the Reflective Systems Unit at MDOT reviewed the state of two- and three-way concurrencies along the highway system in Michigan. They approached
13284-415: The diamond marker used to sign the highways; he is also known for placing a picnic table alongside US 16 (Grand River Avenue) in 1929 south of Saranac , considered the first in the country. Other sources say that the first roadside park in the country was created by Herbert Larson near what is now US 2 near Iron River in 1919–20. The first crows nest traffic tower in the US was installed at
13446-618: The discontinuity, but they have been blocked by local opposition, fearing a loss of business. The Interstate Highway System has been expanded numerous times. The expansions have both created new designations and extended existing designations. For example, I-49 , added to the system in the 1980s as a freeway in Louisiana , was designated as an expansion corridor, and FHWA approved the expanded route north from Lafayette, Louisiana , to Kansas City, Missouri . The freeway exists today as separate completed segments, with segments under construction or in
13608-448: The dissemination of public information. As a result, the 2005 evacuation of New Orleans, Louisiana, prior to Hurricane Katrina ran much more smoothly. According to urban legend , early regulations required that one out of every five miles of the Interstate Highway System must be built straight and flat, so as to be usable by aircraft during times of war. There is no evidence of this rule being included in any Interstate legislation. It
13770-492: The early roads meant that most transportation in the state was by way of the lakes and rivers at first. Commerce was limited to trade to and from Canada. These roads proved inadequate to the needs of the military during the War of 1812 . Territorial Governor Lewis Cass lobbied the federal government for road construction funding to bolster defensive needs as well as aid in settlement of the territory. Military roads debuted in 1816 with
13932-474: The early settlers of the area. The street was the only one of the 30 parallel streets in Highland Park that crossed through the city from border to border and connected with Detroit streets. This road was heavily congested, approaching gridlock during rush hour by 1940. A traffic survey showed that 96% of the traffic using the street was crossing Highland Park with no destination in the city. A proposal to rebuild
14094-492: The eastern end of the concurrency near Breezewood . Traveling in either direction, I-70 traffic must exit the freeway and use a short stretch of US 30 (which includes a number of roadside services) to rejoin I-70. The interchange was not originally built because of a legacy federal funding rule, since relaxed, which restricted the use of federal funds to improve roads financed with tolls. Solutions have been proposed to eliminate
14256-465: The eastern segment carried 37,300 vehicles. The section of freeway in between carried in excess of 50,000 vehicles a day in 2007 between M-10 and I-75. Of this traffic, 1,900 trucks and other commercial vehicles used the trunkline. Davison Avenue predates both the Davison Freeway and the M-8 state trunkline designation in the area. The roadway was named for Jarad Davison, an English immigrant and one of
14418-450: The economy. Not just as a public works measure, but for future growth. Clay's committee proposed a 10-year, $ 100 billion program ($ 1.13 trillion in 2023), which would build 40,000 miles (64,000 km) of divided highways linking all American cities with a population of greater than 50,000. Eisenhower initially preferred a system consisting of toll roads , but Clay convinced Eisenhower that toll roads were not feasible outside of
14580-664: The environment and the Arab Oil Embargo . Even with these cancelled highways, several proposals were left to be completed. At the end of the 1970s, MDOT took part in a FHWA-backed initiative called the Positive Guidance Demonstration Project, and the two agencies audited signage practices in the vicinity of the I-96/M-37 and I-296 /US 131 interchange in Walker near Grand Rapids. MDOT determined that usage of
14742-488: The existing, largely non-freeway, United States Numbered Highways system. By the late 1930s, planning had expanded to a system of new superhighways. In 1938, President Franklin D. Roosevelt gave Thomas MacDonald , chief at the Bureau of Public Roads, a hand-drawn map of the United States marked with eight superhighway corridors for study. In 1939, Bureau of Public Roads Division of Information chief Herbert S. Fairbank wrote
14904-487: The federal government and local counties. There are frequent overlaps between designations when different types of highways share the same stretch of pavement in concurrencies . As just one example of the phenomenon, the freeway between Flint and Standish carries both the I-75 and US 23 designations for around 75 miles (121 km). The State Trunkline Highway System comprises four types of highways: Michigan's portions of
15066-426: The federal government, Interstate Highways are owned by the state in which they were built. With few exceptions , all Interstates must meet specific standards , such as having controlled access, physical barriers or median strips between lanes of oncoming traffic, breakdown lanes , avoiding at-grade intersections , no traffic lights , and complying with federal traffic sign specifications. Interstate Highways use
15228-507: The first three contracts under the new program were signed in Missouri on August 2, 1956. The first contract signed was for upgrading a section of US Route 66 to what is now designated Interstate 44 . On August 13, 1956, work began on US 40 (now I-70) in St. Charles County. Kansas claims that it was the first to start paving after the act was signed. Preliminary construction had taken place before
15390-594: The first time sought to target these funds to the construction of a national road grid of interconnected "primary highways", setting up cooperation among the various state highway planning boards. The Bureau of Public Roads asked the Army to provide a list of roads that it considered necessary for national defense. In 1922, General John J. Pershing , former head of the American Expeditionary Force in Europe during
15552-423: The freeway was extended eastward a few blocks through a junction with the newly opened Chrysler Freeway (I-75) to its present-day eastern terminus near Conant Street. The state requested additional Interstate Highway System mileage that year as well, and in the proposals submitted was a request to extend the Davison to I-96 and I-94 . These plans to transfer the freeway to state control and extend it were dropped in
15714-517: The freeway would have routed US 31 to connect directly into the I-196/US 31 interchange on I-94. Concerns over the habitat of the Mitchell's satyr butterfly meant this routing would need to be redesigned with a set of bridges to cross the habitat unobtrusively in the Blue Creek Fen. In 2001, MDOT began a study of a new design alternative to route the US 31 freeway to connect with I-94 at
15876-449: The freeway's central segment was delayed over concerns related to its routing through Detroit's northern suburbs. The 1,241-mile (1,997 km) Interstate Highway network in Michigan was completed in 1992 with the last four miles (6.4 km) of I-69 near the Lansing area. Since the completion of these freeways, a handful of major projects have added to the trunkline system and the end of
16038-542: The highest speed limits in a given area. Speed limits are determined by individual states. From 1975 to 1986, the maximum speed limit on any highway in the United States was 55 miles per hour (90 km/h), in accordance with federal law. Typically, lower limits are established in Northeastern and coastal states, while higher speed limits are established in inland states west of the Mississippi River . For example,
16200-542: The highly populated coastal regions. In February 1955, Eisenhower forwarded Clay's proposal to Congress. The bill quickly won approval in the Senate, but House Democrats objected to the use of public bonds as the means to finance construction. Eisenhower and the House Democrats agreed to instead finance the system through the Highway Trust Fund , which itself would be funded by a gasoline tax. In June 1956, Eisenhower signed
16362-607: The highway now designated I‑70 and I‑76 opened between Irwin and Carlisle . The Commonwealth of Pennsylvania refers to the turnpike as the Granddaddy of the Pikes, a reference to turnpikes . Milestones in the construction of the Interstate Highway System include: The initial cost estimate for the system was $ 25 billion over 12 years; it ended up costing $ 114 billion (equivalent to $ 425 billion in 2006 or $ 618 billion in 2023 ) and took 35 years. The system
16524-433: The highway's impact to neighboring elementary schools along with larger economic impacts led to the project's cancellation. The Michigan Highway Commission canceled the northern section of I-275 on January 26, 1977, after it spent $ 1.6 million (equivalent to $ 6.67 million in 2023 ) the year before purchasing land for the roadway. This northern section was not planned as an Interstate Highway at that time, bearing
16686-555: The highways. The state's highways are referred to using an M-n syntax as opposed to Route n or Highway n , which are common elsewhere. This usage dates from 1919, when Michigan's state trunklines were first signed along the roadways, and continues to this day in official and unofficial contexts. Michigan is one of only two states following this syntax, the other one being Kansas . Although M-n outside of Michigan could conceivably refer to other state, provincial, local, or national highways, local usage in those areas does not mimic
16848-454: The inefficiency of evacuating from southern Louisiana prior to Hurricane Georges ' landfall in September 1998, government officials looked towards contraflow to improve evacuation times. In Savannah, Georgia , and Charleston, South Carolina , in 1999, lanes of I-16 and I-26 were used in a contraflow configuration in anticipation of Hurricane Floyd with mixed results. In 2004, contraflow
17010-607: The interchange with the eastern terminus of BL I-94 and reconstructing 3.5 miles (5.6 km) of I-94 in the area. Work on that interchange started in September 2020. US 31 was rerouted to follow its new freeway section for 1.8 miles (2.9 km) from the previous end of the freeway at Napier Avenue that opened in 2003 to I-94 at BL I-94, where US 31 then followed I-94 to the I-196 interchange as before. This new routing opened on November 9, 2022. There are several future highway projects current in stages of planning or construction. One
17172-501: The intersection of Woodward and Michigan avenues in Detroit on October 9, 1917. The tower elevated a police officer above the center of the intersection to direct traffic before it was replaced in October 1920 with the world's first four-way traffic light . While Michigan was the second state to post route designations along its highway system in 1919, Michigan actually began assigning internal trunkline designations for internal inventory purposes as early as 1913. From 1918 to 1926, only
17334-431: The last two digits match the parent route (thus, I-294 is a loop that connects at both ends to I-94 , while I-787 is a short spur route attached to I-87 ). In the numbering scheme for the primary routes, east–west highways are assigned even numbers and north–south highways are assigned odd numbers. Odd route numbers increase from west to east, and even-numbered routes increase from south to north (to avoid confusion with
17496-491: The low 200s or under, but some have been designated in the low 300s. MDOT has not assigned a designation outside the Interstate System in the 400s at this time. No discernible pattern exists in Michigan's numbering system, although most of the M -numbered routes lower than 15 are typically located in or around the major cities of Detroit and Grand Rapids . Unlike some other states, there are no formal rules prohibiting
17658-450: The mainline. Some auxiliary highways do not follow these guidelines, however. The Interstate Highway System also extends to Alaska , Hawaii , and Puerto Rico , even though they have no direct land connections to any other states or territories. However, their residents still pay federal fuel and tire taxes. The Interstates in Hawaii, all located on the most populous island of Oahu , carry
17820-737: The maximum speed limit is 75 mph (120 km/h) in northern Maine, varies between 50 and 70 mph (80 and 115 km/h) from southern Maine to New Jersey, and is 50 mph (80 km/h) in New York City and the District of Columbia. Currently, rural speed limits elsewhere generally range from 65 to 80 miles per hour (105 to 130 km/h). Several portions of various highways such as I-10 and I-20 in rural western Texas, I-80 in Nevada between Fernley and Winnemucca (except around Lovelock) and portions of I-15 , I-70 , I-80 , and I-84 in Utah have
17982-548: The modern highways in the state follow the path of these old trails, including the Great Trail from Fort Pitt to Fort Detroit which is now US 24 from Detroit to Toledo , Ohio. This trail connected with Braddock's Road which led to the Atlantic Coast . The Michigan Territory was established in 1805, and the territorial governor established the first road districts. The districts built farm-to-market roads to serve
18144-521: The national standard pentagon-shaped marker in blue and yellow. The letter component of the name corresponds to a zone of the state; zones A–F are in the Lower Peninsula while G and H are in the Upper Peninsula. The numbers correspond to a numbered grid within each lettered zone. Other county systems are designated and maintained in each of the 83 counties, and signage and numbering practices vary. The state's 533 incorporated cities and villages also maintain their own street networks, but townships in
18306-495: The needs of automobiles at the turn of the century. Horatio S. "Good Roads" Earle , a state senator from Detroit, was elected national president of the League of American Wheelmen in 1901. Earle worked on a committee report that called for the removal of the prohibition on road improvements from the state constitution. That report also recommended the creation of a commission and system for state highways. The first state road agency,
18468-404: The number of fatalities on the Interstate Highway System amounted to more than 5,000 people annually, with nearly 5,600 fatalities in 2022. The United States government's efforts to construct a national network of highways began on an ad hoc basis with the passage of the Federal Aid Road Act of 1916 , which provided $ 75 million over a five-year period for matching funds to the states for
18630-561: The original Interstate Highway System was proclaimed complete in 1992, despite deviations from the original 1956 plan and several stretches that did not fully conform with federal standards . The construction of the Interstate Highway System cost approximately $ 114 billion (equivalent to $ 618 billion in 2023). The system has continued to expand and grow as additional federal funding has provided for new routes to be added, and many future Interstate Highways are currently either being planned or under construction. Though heavily funded by
18792-451: The parent highway with the type of special route. The full names are commonly abbreviated like other highways: Business Loop Interstate 196 (BL I-196), Business M-60 (Bus. M-60) or Connector M-44 (Conn. M-44). As of 2010 there are 9,669 miles (15,561 km) of state trunklines in Michigan, making up about eight percent of the state's roadways. Of that mileage, some 4,415 miles (7,105 km) of state-maintained highways are included in
18954-446: The plank roads were generally abandoned. While a few were still in good repair, most consisted of rotting logs with intermittent patches of gravel. Toll houses were empty shacks, and the ditches were clogged with duck ponds. Only 23 of the original 202 plank roads chartered by the state were still in operation. The Good Roads Movement , borne out of the needs of the bicycle craze of the 1880s and 1890s, turned its attention towards
19116-400: The planks would warp and rot. The tolls were insufficient to fund the maintenance necessary to keep the roads in good repair. Even Mark Twain remarked, "The road could not have been bad if some unconscionable scoundrel had not now and then dropped a plank across it," after a trip to Grand Rapids. The planks were removed over time and replaced with gravel roads. The longest chartered road was
19278-481: The planks. Starting with the enactment of a new state constitution in 1850, the state was prohibited from being "a part to, or interested in, any work of internal improvement"; this provision ended the state government's involvement in Michigan's roads. The early plank roads were funded by tolls; these fares were collected at turnstiles every few miles along the roads, at rates of $ 0.02/mile for wagons pulled by two animals (equivalent to $ 0.73 in 2023 ). As time passed,
19440-586: The planning phase between them. In 1966, the FHWA designated the entire Interstate Highway System as part of the larger Pan-American Highway System, and at least two proposed Interstate expansions were initiated to help trade with Canada and Mexico spurred by the North American Free Trade Agreement (NAFTA). Long-term plans for I-69 , which currently exists in several separate completed segments (the largest of which are in Indiana and Texas ),
19602-411: The prefix H . There are three one-digit routes in the state ( H-1 , H-2 , and H-3 ) and one auxiliary route ( H-201 ). These Interstates connect several military and naval bases together, as well as the important communities spread across Oahu, and especially within the urban core of Honolulu . Both Alaska and Puerto Rico also have public highways that receive 90 percent of their funding from
19764-403: The proceeds from the sale of the land adjoining the roads, or with land itself. Despite these efforts, only 1,179 miles (1,897 km) of the 5,082 miles (8,179 km) of plank roads authorized by the state were ever built by 89 of the 202 chartered plank road companies. The tax system was partially reformed in 1881, allowing for direct payment of road taxes instead of relying totally on
19926-498: The proposed freeway, and the project's website was taken offline in 2002. According to 2011 press reports, a group advocating on behalf of the freeway is working to revive the I-73 proposal in Michigan, but state and local governments continue to express disinterest in resurrecting the freeway. Interstate Highway System [REDACTED] The Dwight D. Eisenhower National System of Interstate and Defense Highways , commonly known as
20088-646: The route to indicate so. These unsigned trunklines are mostly segments of former highway designations that have been moved or decommissioned . They remain under state control until their respective city or county accepts jurisdiction of the roadway from the state. Highways in the state maintained by MDOT range from two-lane rural highways up to 12-lane freeways . In addition to the Interstates, other trunklines are built to freeway standards. Sections of US 10 , US 23 , US 31 , US 127 and US 131 have been upgraded to freeway standards. All or part of several state trunklines are also freeways. In
20250-524: The route, without regard to the route number. For instance, I-190 in Massachusetts is labeled north–south, while I-195 in New Jersey is labeled east–west. Some looped Interstate routes use inner–outer directions instead of compass directions, when the use of compass directions would create ambiguity. Due to the large number of these routes, auxiliary route numbers may be repeated in different states along
20412-481: The routing of US 10, and the removal of US 33 from the state. These changes were implemented October 1983, 1985, and 1986, respectively. Other changes recommended at the time, like the truncation of M-54 to remove it from the wrong-way concurrency with M-83 near Birch Run , has never been implemented. The final section of the controversial I-696 opened at a cost of $ 436 million (equivalent to $ 933 million in 2023 ) on December 15, 1989;
20574-419: The same numbers, which is generally disallowed under highway administration guidelines. Several two-digit numbers are shared between unconnected road segments at opposite ends of the country for various reasons. Some such highways are incomplete Interstates (such as I-69 and I-74 ) and some just happen to share route designations (such as I-76 , I-84 , I‑86 , I-87 , and I-88 ). Some of these were due to
20736-503: The same roadway are signed as traveling in opposite directions; one such wrong-way concurrency is found between Wytheville and Fort Chiswell , Virginia, where I‑81 north and I‑77 south are equivalent (with that section of road traveling almost due east), as are I‑81 south and I‑77 north. Auxiliary Interstate Highways are circumferential, radial, or spur highways that principally serve urban areas . These types of Interstate Highways are given three-digit route numbers, which consist of
20898-427: The state after passage of legislation in 1848. According to the plank road law, these companies had to build their roads to a set of minimum specifications. These specifications included 2–4 rods (33–66 ft; 10–20 m) in total width, a road surface 16 feet (4.9 m) wide with at least 8 feet (2.4 m) made of 3-inch (8 cm) planks. Later amendments to the law allowed the companies to substitute gravel for
21060-486: The state have no jurisdiction over roads. The U.S. Forest Service and Federal Highway Administration designate Federal Forest Highways providing access to the handful of National Forests in the state. In addition, Michigan participates in the Great Lakes Circle Tour program, signing tours along the state-maintained highway closest to Michigan's Great Lakes shorelines. The Michigan Heritage Route System
21222-528: The state on both the Upper and Lower peninsulas (UP, LP), which are linked by the Mackinac Bridge . Components of the system range in scale from 10-lane urban freeways with local-express lanes to two-lane rural undivided highways to a non-motorized highway on Mackinac Island where cars are forbidden. The longest highway is nearly 400 miles (640 km) long, while the shortest is about three-quarters of
21384-525: The state received final approval for the numbering system to be used in the state. Michigan was the first state to complete a border-to-border Interstate Highway in 1960 with the completion of I-94. The last gravel state highway was paved in the early 1960s as well; bids were let in March 1962 to finish paving M-48 in Chippewa County . The original goal of Michigan's freeways was to connect every city with
21546-503: The state trunklines in the state highway department. During the 1940s, the first freeways were built in Michigan. With the introduction of the Interstate Highway system in the 1950s, the state aborted an effort to build the Michigan Turnpike , a tolled freeway in the southeast corner of the LP. Construction on Michigan's Interstates started in the latter part of that decade and continued until 1992. During that period, several freeways were canceled in
21708-411: The state. MDOT assigns the numbers for a parallel system of county-designated highways in the state; the numbers are assigned in a grid system by the department. These highways, while signed from connecting trunklines and shown on the official MDOT map, are maintained by the various counties. They were started in 1970 as a supplement to the main trunkline system and carry a letter-number combination on
21870-405: The state. Many former US Highways in Michigan have left an M -numbered highway with the same number as a relic of their existence. For example, M-27 runs along a portion of former US 27 . In addition, there are two occurrences of original M -numbered state routes which became US Highways with the same designations: all of M-16 became US 16 and most of M-10 from Detroit to Saginaw
22032-590: The state. The post-war years were also a period of major bridge building in the state. The Mackinac Bridge opened on November 1, 1957, the Portage Lake Lift Bridge , the largest double-deck lift bridge was completed in August 1959, and the International Bridge opened across the St. Marys River three years later on October 31, 1962. The State Highway Department started erecting mileposts along
22194-401: The state. Further legislation at the time allowed for special assessment taxing districts for road improvements, taxation of automobiles based on weight and horsepower, and tree-planting along highway roadsides. Congress passed the Federal Aid Road Act of 1916 , and the state passed a constitutional amendment in 1917 to qualify for federal aid with state funding matches. The first centerline
22356-411: The state. In 1974, the state implemented mileage-based exit numbers along the remaining Interstates in Michigan. By late 1977, the state highway department shifted its focus from construction of new highways to improvements of the existing system. During the 1960s and 1970s, various freeway projects in the Detroit area were cancelled or scaled back in scope. The route of I-96 along Grand River Avenue
22518-399: The state. The existing tri-level system was maintained, splitting road jurisdiction between the state, counties and cities, as well as subdividing each level into several classifications. Further legislation redefined the exact distribution, but Act 51 set up a system to distribute road funding from gas taxes from a single funding source, currently the Michigan Transportation Fund. Funding
22680-457: The statute-labor system. The first road district larger than the township level was created in Bay County in 1883 under Public Act 278. This road district encompassed eight townships and provided for better coordination and planning of road construction. Other county systems were created in 1893 with passage of legislation which allowed other counties to follow the lead of Bay County. By 1900,
22842-468: The street as a six-lane, limited-access highway was approved by the Highland Park City Council on March 17, 1941. The council also appropriated $ 100,000 (equivalent to $ 1.6 million in 2023) for the construction with Wayne County and the remaining $ 3,400,000 (equivalent to $ 54.3 million in 2023) paid by state and federal government appropriations. The freeway construction required
23004-522: The township-controlled roads into 83 county road commissions. On May 4, 1935, the state opened the first highway welcome center next to US 12 in New Buffalo near the Indiana state line; Michigan was the first state in the country to do so at the time. The state passed legislation in 1941 that authorized the creation of limited-access roadways; the MSHD could prohibit access to a state trunkline from
23166-433: The two highways. M-131 was an extension of US 131 until US 131 was routed onto the former M-131. There was also once an M-112 that served as an alternate routing for US 112 (both have since been changed to I-94 and US 12, respectively). There are four types of highways maintained by MDOT as part of the overall State Trunkline Highway System. In addition, there are systems of roads maintained by
23328-569: The usage of the same route number under different systems. Motorists using Michigan's highways may encounter I-75 and M-75 , as well as both US 8 and M-8 . Many of the state's US Highways were assigned numbers duplicating those of state trunklines when the US Highway System was created in 1926. The introduction of the Interstate Highway System in the late 1950s further complicated the situation, as each mainline Interstate designation has an unrelated M-n trunkline counterpart elsewhere in
23490-537: The void in long-distance road construction left by the departure of the federal government. The first roads were corduroy roads ; to build these, logs of all sizes were placed across the road. The gaps between the logs were filled in with smaller logs or earth. In swampy or marshy areas, brush was laid down first for drainage. In time, the logs would rot, leaving large gaps to the roadway that would catch wagon wheels or draft animal feet. Later, roads were built with oak planks. The plank road companies had to be chartered by
23652-490: The war, complied by submitting a detailed network of 20,000 miles (32,000 km) of interconnected primary highways—the so-called Pershing Map . A boom in road construction followed throughout the decade of the 1920s, with such projects as the New York parkway system constructed as part of a new national highway system. As automobile traffic increased, planners saw a need for such an interconnected national system to supplement
23814-524: The war, the MSHD and the Good Roads Federation studied the highway needs of the state. Their study reported that road maintenance and improvement deteriorated since the Great Depression . It also stated that funding needed to be increased to deal with pressures from traffic increases after the war. Public Act 51 of 1951 amended and clarified the current system of jurisdiction over roads in
23976-494: The western end at an interchange with I-96 in Detroit. Davison Avenue continues west of this interchange forming a service drive for the freeway while M-8 uses a short section of freeway to connect between I-96 and Davison Avenue. This short freeway segment runs easterly to Livernois Avenue where the trunkline transitions into Davison Avenue. East of this transition, the roadway turns northeasterly running through residential areas of Detroit. The trunkline meets M-10 /Lodge Freeway on
24138-404: Was abolished in 1907. Instead, a property tax system was instituted with the funding only for permanent improvements, not maintenance. Rural farmers opposed the state's efforts, and even Henry Ford was against the idea of reforming road construction and maintenance. In response to this opposition, the department's work was decentralized; standards for road improvement came from the state, but work
24300-453: Was assumed into the route of US 10 in 1926. In fact, each iteration of M-10 has existed in whole or part along a former or future alignment of US 10. There are also instances of M -numbered state highways that once existed as extensions of US Highways. M-25 was originally an extension of US 25 before the latter was decommissioned in Michigan, and M-24 was once an extension of US 24 before routing changes separated
24462-641: Was cancelled in response to freeway revolts in the city, and a new routing along the C&;O Railroad right-of-way in Livonia was used instead. Plans to transfer the Davison Freeway in the 1970s to state control and extend it west to I-96 (Jeffries Freeway) and east to a Van Dyke Freeway (extended M-53 ) were dropped. Another freeway project near Lansing, the Van Atta Connector, was proposed in 1961 to provide an eastern freeway beltway around East Lansing, but by 1981
24624-438: Was carried out by the townships and counties. The nation's first mile of concrete roadway was laid along Woodward Avenue in 1909 between Six Mile and Seven Mile roads in Detroit; this section of street was 17 feet 8 inches (5.38 m) wide and cost $ 14,000 (equivalent to $ 339,600 in 2023). Passage of the State Reward Trunk Line Highways Act on May 13, 1913, provided for 3,000 miles (4,828 km) of roadways in
24786-404: Was created in 1993 to highlight trunklines with historic, recreational or scenic qualities; the name was changed to Pure Michigan Byway on December 30, 2014. The history of the highway system in Michigan dates back to the old Native American trails that crossed the state. These trails were pathways no wider than approximately 12–18 inches (30–46 cm), permitting single-file traffic. Many of
24948-541: Was employed ahead of Hurricane Charley in the Tampa, Florida area and on the Gulf Coast before the landfall of Hurricane Ivan ; however, evacuation times there were no better than previous evacuation operations. Engineers began to apply lessons learned from the analysis of prior contraflow operations, including limiting exits, removing troopers (to keep traffic flowing instead of having drivers stop for directions), and improving
25110-463: Was increased during the 1950s as the fuel taxes were increased. Whereas those revenues during the war dropped to levels barely sufficient to keep existing highways in usable condition, they were increased during the following decade to deal with increasing traffic. The state highway department was also authorized to sell bonds to provide funding for the proposed road improvements. The Michigan Turnpike Authority (MTA), an agency created in 1951, proposed
25272-492: Was originally the only street connecting across Highland Park to Detroit. It was rebuilt by the city and Wayne County as a freeway during World War II . The roadway was transferred to the jurisdiction of the Michigan Department of Transportation (MDOT) in 1993 and numbered as M-8. Subsequent changes by the state rebuilt the freeway and extended the M-8 designation to connect to the Jeffries Freeway ( I-96 ). M-8 starts on
25434-600: Was painted on a state highway in 1917 along the Marquette–Negaunee Road which was designated Trunkline 15, now County Road 492 in Marquette County . Winter maintenance started during World War I to keep 590 miles (950 km) of strategic highways clear; some $ 13,200 (equivalent to $ 177,600 in 2023 ) was appropriated with partial funding from the War Loan Board . In 1919, the legislature passed
25596-422: Was proclaimed complete in 1992, but two of the original Interstates— I-95 and I-70 —were not continuous: both of these discontinuities were due to local opposition, which blocked efforts to build the necessary connections to fully complete the system. I-95 was made a continuous freeway in 2018, and thus I-70 remains the only original Interstate with a discontinuity. I-95 was discontinuous in New Jersey because of
25758-410: Was quite different. Maps of the territory were printed with the words "interminable swamp" across the interior until 1839. Reports of the first explorers and government surveyors crossing the future state only seemed to confirm the assessment that Michigan land was unsuitable for agriculture or other productive activities. The few roads in the area were impassable for half of the year. The poor quality of
25920-494: Was serving as Supreme Commander of Allied Forces in Europe during World War II . In 1954, Eisenhower appointed General Lucius D. Clay to head a committee charged with proposing an interstate highway system plan. Summing up motivations for the construction of such a system, Clay stated, It was evident we needed better highways. We needed them for safety, to accommodate more automobiles. We needed them for defense purposes, if that should ever be necessary. And we needed them for
26082-405: Was unable to work off the tax, a rate of $ 0.625/day was assessed (equivalent to $ 22.89 in 2023 ). This road maintenance was performed under the guidance of the township road overseer, a separate elected township official, according to the wishes of his constituents, often without any county-level planning or coordination. Often the "improved roads" were in worse condition than unimproved roads due to
26244-400: Was used for the lines separating directions of travel and white for lines separating lanes traveling in the same direction. Also in 1972, a gas tax increase was passed to facilitate US and state highway improvement projects. The final section of I-75 between Alger and Roscommon was opened on November 1, 1973, in a dedication by Governor William G. Milliken , completing the longest highway in
