128-457: The counties that constitute the Thumb form the peninsula that stretches northward into Lake Huron and Saginaw Bay . There is no formal list of which counties are part of the Thumb, but virtually all definitions include Huron , Tuscola , and Sanilac counties, and most include Lapeer and St. Clair counties. The population of the Thumb region as of the 2020 census was 370,617. The Thumb region

On the eve of European contact, the extent of development among Eastern Woodlands Native American societies is indicated by the archaeological evidence of a town on or near Lake Huron that contained more than one hundred large structures housing a total population of between 4,000 and 6,000. The French, the first European visitors to the region, often referred to Lake Huron as La Mer Douce, "the fresh-water sea". In 1656,
384-664: A dominant influence until after the War of 1812, when the northern border was firmly defined and this area came under US control. The US organized the Northwest Territory, and American settlement of Michigan and the Thumb was well underway by the mid-19th century.

The demersal fish community of
1408-485: A reference to the rounded stones, or flint pebbles, found in the rivers and streams throughout the area. Another theory is that it may be an English variation of Le Pays Plat , meaning "the flat land", which is one of the original names given to the area by the French, and can be found on many early fur trader maps of the area. The idea is that "Le Pays" may have evolved into the current pronunciation, "Lapeer". Lapeer County

There may have also been other tribes in the area such as the Potawatomi , Ojibwe , and Kickapoo , but they would have been transient tribes, or found in very small numbers. All native Thumb area tribes are members of the Algonquian peoples , a large language family. Other tribes who migrated later into the area included the Wyandot ( Huron ), an Iroquoian language-speaking people; and
9216-530: The area. 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. In December 2022, the Michigan Department of Transportation (MDOT) procured a statewide tolling study. Under
9344-610: The center of Detroit was being planned in the 1940s, it was unofficially named the Harper–McGraw Expressway after the streets along which it was to run. There was some initial support to name it after Roy D. Chapin , the late president of the Hudson Motor Car Company and a former US secretary of commerce under President Herbert Hoover . On April 23, 1946, the Detroit Common Council voted instead to name
9472-460: The county being bordered by water: on the east is the St. Clair River, connecting Lake Huron to the north to Lake St. Clair . Below that is the Detroit River. The namesake Blue Water Bridge spans the St. Clair River, connecting Port Huron to Sarnia, Ontario . A similar name, "Blue Water Country," is used to describe the same region on the Canadian side. Discover the Blue is a promotion by
9600-538: The crossing was eliminated when the tracks were removed in 1968. The sections originally designated as the Willow Run Expressway were rebuilt from Rawsonville Road in Belleville to Ozga Road in Romulus starting in 1972. As part of this reconstruction, the segment between Haggerty and Ozga roads was widened from four to six lanes, and the eastbound lanes were realigned to facilitate construction of an interchange with I-275 ,
9728-401: The economy. Caro , one of the largest cities in the Thumb (the largest if you exclude St. Clair and Lapeer counties), is named after Cairo, Egypt and is the county seat. Tuscola County only has 18 miles (29 km) of shoreline along Saginaw Bay , so it is not as dependent on tourism as the other counties in the area. Tuscola County is economically tied to the surrounding region as well as to
9856-563: The end of I-69 / I-94 in Port Huron at the foot of the Blue Water Bridge and ends in Bay City . The whole highway is about 150 miles (240 km), and passes through quaint cities and villages. Located along Lake Huron through which M-25 passes are five lighthouses: Fort Gratiot Lighthouse , Port Sanilac lighthouse , Pointe aux Barques Lighthouse , Harbor Beach Light , and the Port Austin Lighthouse . The Lake Huron Circle Tour
9984-487: The first state to complete a border-to-border toll-free Interstate within their state, running for 205 miles (330 km) from Detroit toward New Buffalo, creating the longest toll-free freeway in the country at the time. In January 1962, the US ;12 designation was removed from the I-94 freeway. In the process, the designation was transferred to replace the US 112 designation in its entirety. After this transfer, I-94
10112-514: The freeway from the New Baltimore area northward. The eastern terminus of I-94 in the Port Huron area was dedicated on October 14, 1964, signaling the completion of the highway between Marysville and the Blue Water Bridge. This completion displaced part of the M-146 bypass of Port Huron, the southern leg of which was retained as a connector to present-day Lapeer Road. Two years later, the gap between
10240-404: The freeway's right lane, while also moving the carriageways of I-94 closer together. On August 16, 1987, Northwest Airlines Flight 255 crashed after attempting to take off from Detroit Metropolitan Airport , killing all but one passenger upon exploding at the I-94 overpass over Middlebelt Road; that overpass was not damaged in the crash. The freeway was closed until August 18, and a memorial
10368-762: The freeway, the Legislature added the designation by passing Public Act 305 of 2002. The name was dedicated in ceremonies at a rest stop along the section of I-94 on September 28, 2002. Another piece of I-94 in Calhoun County was designated in 2004 as part of the Underground Railroad Memorial Highway. Starting in 1990, the National Park Service started working to identify routes of the Underground Railroad . The Battle Creek area
10496-478: The highest lake levels in October and November. The normal high-water mark is 2.00 feet (0.61 m) above datum ( 577.5 ft or 176.0 m ). In the summer of 1986, Lakes Michigan and Huron reached their highest level at 5.92 feet (1.80 m) above datum. The high-water records were broken for several months in a row in 2020. Historic low water Lake levels tend to be the lowest in winter. The normal low-water mark
10624-557: The highway after Edsel Ford , the son of Henry Ford and president of the Ford Motor Company from 1918 until his death in 1943. Two other original sections of I-94's predecessor highways in the Detroit area were given early names. The westernmost of these is the Willow Run Expressway, named for the Willow Run complex. The plants at Willow Run produced B-24 Liberator bombers for Ford Motor Company during World War II. The second,
10752-670: The highway signs. A segment of I-94 in Battle Creek between the exits for BL I-94 and I-194 was named the 94th Combat Infantry Division Memorial Highway by the Michigan Legislature in 2002. The name honors the US Army's 94th Infantry Division , which was activated at nearby Fort Custer in 1942 and served with distinction in the European theater of World War II. Because the unit originated in Battle Creek, and its number matched that of
10880-400: The hull. To keep from being pushed aground, they kept their bow into the wind with the engines running half to full in turns, yet the ship still drifted 800 feet (240 m) before its movement was arrested. Waves breaking over the ship damaged several windows, and the crew reported seeing portions of the concrete break wall peeling off as the waves struck it. Meanwhile, fifty miles farther up
11008-434: The lake bed was criss-crossed by a large network of tributaries to these ancient waterways, with many of the old channels still evident on bathymetric maps. The Alpena-Amberley Ridge is an ancient ridge beneath the surface of Lake Huron, running from Alpena, Michigan , southwest to Point Clark , Ontario. About 9,000 years ago, when water levels in Lake Huron were approximately 100 m (330 ft) below today's levels,
11136-437: The lake by the 1930s. The major native top predator, lake trout, was virtually extirpated from the lake by 1950 through a combination of overfishing and the effects of sea lamprey. Several species of ciscos were also extirpated from the lake by the 1960s; the only remaining native ciscoes are bloater and Cisco (lake herring). Non-native Pacific salmon have been stocked in the lake since the 1960s, but are less abundant since
11264-432: The lake was in a state of collapse by 2006, and a number of drastic changes have been observed in the zooplankton community of the lake. Chinook salmon catches have also been greatly reduced in recent years, and lake whitefish have become less abundant and are in poor condition. These recent changes may be attributable to the new exotic species. Some native species, however were beneficiaries of these chances (principally
11392-646: The lake, Matoa and Captain Hugh McLeod had to ride out the storm without a safe harbor. Matoa was found stranded on the Port Austin reef when the winds subsided. It was noon on Monday before the winds let up and not until 11:00 p.m. that night before Captain Light determined it to be safe to continue his journey. Although Manola survived the storm, she was renamed Mapledawn in 1920, and on November 24, 1924, she became stranded on Christian Island in Georgian Bay. It

North of 26 Mile Road, the freeway exits the northern suburbs and passes into farmland in The Thumb region. South of Michigan Meadows Golf Course, I-94 crosses County Line Road and enters St. Clair County . The freeway continues northeasterly as far as Marysville before turning northward near St. Clair County International Airport . From there, it runs roughly parallel to
11648-523: The largest city on Lake Huron. On October 26, 2010, the Karegnondi Water Authority was formed to build and manage a pipeline from the lake to Flint, Michigan . More than a thousand wrecks have been recorded in Lake Huron. Of these, 185 are located in Saginaw Bay, and 116 are found in the 448-square-mile (1,160 km ) Thunder Bay National Marine Sanctuary and Underwater Preserve , which
11776-485: The late 18th century, ethnic European Americans have displaced the Native American tribes that historically occupied this territory. Since the early 20th century, they have dominated the population and culture of the Thumb. The French were the first Europeans to arrive, and thus influenced much of the early culture. They were mostly engaged in the fur trading and lumber industries, and had relatively few settlers. After
11904-529: The maximum recorded (by sonar) depth is 125 fathoms (750 ft; 229 m). It has a length of 206 statute miles (332 km ; 179 nmi ) and a greatest breadth of 183 statute miles (295 km; 159 nmi). A large bay that protrudes northeast from Lake Huron into Ontario, Canada, is called Georgian Bay . A notable feature of the lake is Manitoulin Island , which separates the North Channel and Georgian Bay from Lake Huron's main body of water. It
12032-545: The middle of the southern Lower Peninsula, crossing I-69 in the process. I-94 then runs through Jackson , Ann Arbor , and portions of Metro Detroit , connecting Michigan's largest city to its main airport . Past the east side of Detroit , the Interstate angles northeasterly through farmlands in The Thumb to Port Huron , where the designation terminates on the Blue Water Bridge at the Canada–United States border . The first segment of what later became I-94 within
12160-576: The morning, Senator pushed upstream. Less than an hour later, Manola —a propeller freighter of 2,325 gross register tons also built in Cleveland in 1890—passed through. Captain Frederick W. Light of Manola reported that both the Canadian and the American weather stations had storm flag signals flying from their weather towers. Following behind at 7:00 a.m. that Sunday, Regina steamed out of Sarnia into
12288-421: The northwest gale. The warnings had been up for four hours. Manola passed Regina off Port Sanilac, 22 statute miles (19 nmi; 35 km) up the lake. Captain Light determined that if it continued to deteriorate, he would seek shelter at Harbor Beach , Michigan, another 30 statute miles (26 nmi; 48 km) up the lake. There, he could seek shelter behind the breakwater. Before he reached Harbor Beach,
12416-480: The northwest to round Beadle Lake , intersecting M-294 before spanning the Kalamazoo River. East of the river crossing, the freeway meets an interchange for M-96 , M-311 , and the eastern end of the Battle Creek business loop near FireKeepers Casino Hotel in Emmett Township . Turning back eastward, the Interstate exits the eastern Battle Creek suburbs and continues to an interchange with I-69 near Marshall ;
12544-626: The only driveway on any of Michigan's Interstate Highways for a gate providing access for military vehicles into the Fort Custer Training Center . The Interstate enters Calhoun County southwest of the W. K. Kellogg Airport and enters the city of Battle Creek. Immediately east of the county line, the freeway has an interchange with the western end of Battle Creek's business loop . Next to Lakeview Square Mall , I-94 meets its only auxiliary Interstate in Michigan: I-194 . I-94 turns to
12672-451: The rail line, special boarding stations adjacent to dedicated bus lanes in the interchanges along the highway were used. In other parts of the state, other segments of highway were built to bypass the cities along the future I-94 corridor. In 1940, a southern bypass of Battle Creek opened along Columbia Avenue, and the former routing through downtown on Michigan Avenue became Business US 12 (Bus. US 12). In late 1951 or early 1952,
12800-524: The river, the Interstate designations jointly terminate, becoming Ontario Highway 402 . The first major overland transportation corridors in the future state of Michigan were the Indian foot trails. One of these, the St. Joseph Trail, followed the general route of the modern I-94 across the state from the Benton Harbor – St. Joseph area east to the Ann Arbor area. The State Trunkline Highway System
12928-423: The same lake'). Aggregated, Lake Huron-Michigan, at 45,300 square miles (117,000 km ), "is technically the world's largest freshwater lake". Lake Superior, at 21 feet higher elevation, drains into the St. Marys River which then flows into Lake Huron. The water then flows south to the St. Clair River, at Port Huron, Michigan and Sarnia, Ontario . The Great Lakes Waterway continues thence to Lake St. Clair ;
13056-432: The same surface elevation as Lake Michigan , to which it is connected by the 5-mile-wide (8.0 km), 20-fathom-deep (120 ft; 37 m) Straits of Mackinac . Combined, Lake Michigan–Huron is the largest freshwater lake by area in the world. The Huronian glaciation was named from evidence collected from Lake Huron region. The northern parts of the lake include the North Channel and Georgian Bay . Saginaw Bay
13184-415: The second span between Port Huron and Point Edward, Ontario in 1995. In July 1997, the second span opened. The original span was closed for rehabilitation, and both were opened to traffic in 1999. The interchange with US 24 (Telegraph Road) following its mid-1960s redesign had only two bridges, and left-hand exits were used throughout. This interchange was reconfigured in 2005 to a SPUI design that
13312-410: The shoreline of Lake St. Clair , and exits Detroit for Harper Woods . Just north of the interchange for M-102 (Vernier Road), the freeway crosses 8 Mile Road and enters Macomb County . Running northward through Macomb County, I-94 meets the eastern end of I-696 (Reuther Freeway) about three miles (4.8 km) north of the county line in St. Clair Shores . The freeway continues to parallel
13440-460: The shoreline, which are Caseville Park, Lighthouse Park, Stafford Park, McGraw Park, Philp Park, Port Austin Bird Creek Park, Wagener Park, Oak Beach Park, and Sebewaing Park. The county seat is Bad Axe , located in the center of the county. The origin of the name of the county is often disputed, but it may have derived from the French words la pierre , meaning "the stone". This name could be
13568-460: The southeastern corner of Ann Arbor, I-94 intersects US 23 and continues around the south side of Ypsilanti . South of that city, the freeway also carries US 12 and crosses the Huron River north of the river's mouth at Ford Lake . I-94 jogs southeasterly around the south side of Willow Run Airport complex, separating from US 12 and entering Wayne County . South of Willow Run,
13696-516: The southeastern corner of Kalamazoo before entering Comstock Township . The freeway intersects the eastern end of Business Spur I-94 (BS I-94) at a partial interchange near Morrow Lake in the township. I-94 continues out of the eastern Kalamazoo suburbs, paralleling the Kalamazoo River through the Galesburg area. Before crossing into Calhoun County on the west side of Battle Creek , I-94 has
13824-523: The state's Interstate Highways was placed on hold pending finalization of the numbering scheme, and by late 1959 that signage was being added starting with I-75 and followed by the other open segments of freeway in the state. Sections of freeway opened in southwestern Michigan in 1960 between the Benton Harbor–St Joseph area and between Jackson and Ann Arbor; the latter was built over existing portions of US 12. In this year, Michigan became
13952-409: The state, the Willow Run Expressway, was built near Ypsilanti and Belleville in 1941, with an easterly extension to Detroit in 1945. This expressway was initially numbered M-112 . In the mid-1950s, state and federal officials planned an Interstate to replace the original route of US Highway 12 (US 12). By 1960, the length of I-94 was completed from Detroit to New Buffalo. Two years later,
14080-422: The study, I-94 would be the first highway to be converted into a toll road starting in 2028. Lawmakers have not yet acted upon the department's recommendation in the proposal. Construction began on August 7, 2023, on a privately funded three-mile (4.8 km) MDOT pilot project to upgrade the left lane for connected and autonomous vehicles between Ann Arbor and Detroit. As the original expressway through
14208-583: The territory of the NMDC. The I-69 International Trade Corridor Next Michigan Development Corporation is the largest in the state of Michigan with 35 municipal partners. Constituent counties of the trade corridor are: Shiawassee , Genesee , Lapeer , and St. Clair counties. Some towns, such as Bay Port , Caseville , Harbor Beach , Lakeport, Lexington , Port Austin , Port Hope , Port Huron , Port Sanilac , Sebewaing , and St. Clair enjoy seasonal tourism, due to their locations on Lake Huron , Saginaw Bay , or
14336-525: The trunkline turns eastward and roughly follows the Paw Paw River on a course that takes it south of Watervliet and Hartford . Between the latter two cities, the freeway transitions from northeastern Berrien County into western Van Buren County . It curves around and between Lake Cora and Threemile Lake near the junction with the northern end of M-51 . About four miles (6.4 km) further east, I-94 crosses M-40 south of Paw Paw . Continuing eastward,
14464-443: The winds turned to the northeast and the lake began to rise. It was noon when he reached Harbor Beach and ran for shelter. The waves were so violent that Manola touched bottom entering the harbor. With help from a tugboat , Manola tied up to the break wall with eight lines. It was about 3:00 p.m. when Manola was secured and the crew prepared to drop anchor. As they worked, the cables began to snap from wind pressure against
14592-482: The world's supply of navy beans. Tourism is also important to Huron County with bay front and lakefront towns such as Sebewaing , Caseville , Port Austin , Port Hope , and Harbor Beach , attracting tourists from all over.

Also, Huron County maintains nine county parks along
14720-564: Was M-19 from Detroit northeast to Port Huron . On November 11, 1926, the United States Numbered Highway System was approved by the American Association of State Highway Officials (AASHO), and the original route of US 12 replaced the highways from the state line northeasterly to Detroit; US 31 overlapped the highway between St. Joseph and Watervliet . The remainder of the future I-94 corridor
14848-570: Was active in the railroad during the Civil War, and the section of I-94 between exits 98 and 110 east of Battle Creek was included in the memorial designation. In June 2012, after a resolution passed by the Michigan Legislature was signed by Governor Rick Snyder , a portion of I-94 in Taylor between Inkster and Pelham roads was named the Auxiliary Lt. Dan Kromer Memorial Highway after a 20-year veteran of
14976-729: Was completed in December of that year. A pair of bridges called the Gateway Arch Bridges (alternately "Gateway to Detroit" ) was incorporated in the new interchange. In 2011, construction was started to widen I-94/I-69 approaching the Blue Water Bridge and to allow for dedicated local traffic and bridge traffic lanes. The lane configuration changes confused drivers in the area, especially motorists with outdated GPS devices; because of this, MDOT installed updated signs complete with American and Canadian flags to help prevent drivers from heading to Canada by mistake. Additional construction in
15104-628: Was completed in September 2015. In 2016, the sections of I-94 from the Indiana state line to the M-63 interchange was designated as part of the West Michigan Pike Pure Michigan Byway . The West Michigan Pike originated in efforts in the 1910s to improve a highway along the western part of the Lower Peninsula of Michigan and to increase tourism along the Lake Michigan shore. The auto trail
15232-540: Was created on May 13, 1913, by an act of the Michigan Legislature ; at the time, Division 6 corresponded to the rough path of today's I-94. In 1919, the Michigan State Highway Department (MSHD) signposted the highway system for the first time, and three different highways followed sections of the modern I-94 corridor. The original M-11 ran from the Indiana state line north to Coloma where M-17 connected easterly to Detroit . The third highway
15360-540: Was declared a total loss. Salvagers were able to recover approximately 75,000 bushels of barley. Lake Huron has a lake retention time of 22 years. Like all of the Great Lakes, the ecology of Lake Huron has undergone drastic changes in the last century. The lake originally supported a native deepwater fish community dominated by lake trout , which fed on several species of ciscos as well as sculpins and other native fishes. Several invasive species , including sea lamprey , alewife and rainbow smelt , became abundant in
15488-477: Was dedicated. This last segment in Michigan between M-239 and the state line opened when Indiana completed an 18-mile (29 km) segment of freeway in their state. The interchange with the Southfield Freeway ( M-39 ) was closed entirely in 1985 to replace the original exit design, which included four on-ramps that sharply merged into the left lanes of I-94. Reconstruction added new on-ramps that merge into
15616-474: Was eclipsed in January 2013. Lake Huron has the largest shore line length of any of the Great Lakes, counting its 30,000 islands. It is separated from Lake Michigan, which lies at the same level, by the 5-mile-wide (8.0 km), 20-fathom-deep (120 ft; 37 m) Straits of Mackinac, making them hydrologically the same body of water (sometimes called Lake Michigan-Huron and sometimes described as two 'lobes of

Robert Cavalier, Sieur de la Salle navigated across Lake Erie, up the Detroit River , Lake St. Clair and the St. Clair River out into Lake Huron. Passing
15872-427: Was eventually superseded by US 12 and US 31 after the creation of the United States Numbered Highway System in 1926. In 2020, work began on the final link of the St. Joseph Valley Parkway to connect the US 31 freeway to I-94 east of Benton Harbor. The project cost $ 121.5 million and involved reconstructing the interchange with the eastern terminus of BL I-94 and 3.5 miles (5.6 km) of I-94 in
16000-593: Was given the M-112 designation at the time. The expressway was extended eastward as the Detroit Industrial Expressway into Detroit; the first section opened in 1943 and the remainder was completed in March 1945. Land acquisition for the Edsel Ford Freeway started in 1945. Originally referred to as the Crosstown Freeway, the freeway became known as the Edsel Ford Freeway following an April 1946 petition. The interchange between
16128-543: Was later installed near the interchange between I-94 and Middlebelt Road. The completion of I-69 in the 1980s, and the approval of the North American Free Trade Agreement , increased traffic at the Blue Water Bridge. A new toll and customs plaza was built in 1991, and, later the next year, an international task force determined that traffic on the existing structure was exceeding capacity. Environmental planning started in 1993, and construction started on
16256-538: Was no longer concurrent with US 12, except for the Ypsilanti bypass. In 1963, the freeway was extended south of New Buffalo to end at M-239 . Traffic was diverted down M-239 into Indiana where State Road 39 carried traffic the rest of the way to the Indiana Toll Road . By the end of the year, a section of highway opened between Mount Clemens and Marysville, and US 25 was rerouted to run concurrently along
16384-493: Was served by US 25 between Detroit and Port Huron. The first span of the Blue Water Bridge opened between Port Huron and Point Edward, Ontario , in 1938. The first segments of upgraded highways along the future route of I-94 were added during World War II . Construction on the Willow Run Expressway started in 1941 before the US entered the war. It was opened on September 12, 1942, to provide improved access to Ford Motor Company 's Willow Run bomber plants. The highway
