98-641: Interstate 85 ( I-85 ) is a major Interstate Highway in the Southeastern United States . Its southern terminus is at an interchange with I-65 in Montgomery, Alabama ; its northern terminus is an interchange with I-95 in Petersburg, Virginia , near Richmond . It is nominally north–south as it carries an odd number, but it is physically oriented northeast–southwest and covers a larger east–west span than north–south. While most Interstates that end in
196-584: A T intersection off I-65 in Montgomery . From there, I-85 parallels US 80 until the highway nears Tuskegee . At Tuskegee, I-85 leaves US 80 and starts to parallel US 29 , which the highway parallels for much of its length. I-85 also passes near Auburn , Opelika , Valley , and Lanett before crossing the Chattahoochee River into Georgia . I-85 is planned to be rerouted southward just east of Montgomery, where it will intersect with I-65 just south of downtown Montgomery and then have
294-522: 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

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

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
1274-481: 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,

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
1470-409: 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

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
2646-474: 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

This numbering system usually holds true even if the local direction of the route does not match the compass directions. Numbers divisible by five are intended to be major arteries among the primary routes, carrying traffic long distances. Primary north–south Interstates increase in number from I-5 between Canada and Mexico along
3528-491: 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

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

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

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
7056-431: 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
7154-450: 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
7252-737: 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
7350-474: The newly created Pendleton district. Anderson was settled in 1826 and incorporated in 1828 as Anderson Court House, separate from the Pendleton district. The name Anderson is in honor of Robert Anderson , who fought in the American Revolutionary War and also explored the Anderson region in the mid-18th century. Anderson District (later Anderson County after 1867) was also established in 1826 out of
7448-486: The north where it junctions with I-77 . North of Charlotte, the highway passes near Concord , Salisbury , Lexington , and High Point before reaching Greensboro . At Greensboro, I-85 shifts away from downtown I-85 Bus (old I-85 through town). I-85 then joins I-40 east of downtown, and the two highways are cosigned as they pass through Burlington , Graham , and Mebane then separate near Hillsborough where I-40 turns toward Chapel Hill , Cary , and Raleigh . After
7546-404: 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
7644-423: The official Interstate Highway standards . On one- or two-digit Interstates, the mile marker numbering almost always begins at the southern or western state line. If an Interstate originates within a state, the numbering begins from the location where the road begins in the south or west. As with all guidelines for Interstate routes, however, numerous exceptions exist. Anderson, South Carolina Anderson
7742-561: 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
7840-475: The overall length for I-85 in North Carolina remains the same as before. On the evening of March 30, 2017 a massive fire collapsed a bridge on I-85 in Atlanta. As a result, I-85 was closed to traffic for approximately two miles (3.2 km) between its split with I-75 and the interchange with SR 400 . An extension of I-85 has been proposed west from Montgomery to intersect I-20 / I-59 just east of
7938-633: 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 ),
8036-487: The plastic and automotive sectors. More than 27 BMW suppliers are the Upstate region, which is recognized internationally as an automotive supplier hub. The plastics industry has a strong presence in the Upstate, with 244 plastic companies located within the 10 counties of the state's northwest corner. Anderson County, in particular, has 11 automotive suppliers and is a major player in the plastic industry, with 27 plastics companies located within its borders. AnMed Health
8134-521: The population. Anderson is home to the largest Glen Raven, Inc. manufacturing center facility, which focuses on manufacturing Sunbrella fabrics. Anderson's economy revolves around manufacturing . It has over 230 manufacturers, including 22 international companies. In the county, Anderson has a thriving business climate. Its top major industries include manufacturers of automotive products, metal products, industrial machinery, plastics, publishing, and textiles. Two industries that many times interconnect are
8232-411: 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
8330-524: 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
8428-475: The same general path as US 1 (Boydton Plank Road and Jefferson Davis Highway ), as the two cross several times between the North Carolina border and the northern terminus outside Petersburg. In the northern half of I-85, the route roughly parallels an ancient Indian trading path documented since colonial times from Petersburg, Virginia, to the Catawba Indian territory. I-85 near Petersburg once formed
8526-419: 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
8624-503: 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
8722-536: The southern end of the Richmond–Petersburg Turnpike , which was completed in 1958. The tolls were removed in 1992 after I-295 was completed. Before a 2010 decision to raise the speed limit in the state to 70 mph (110 km/h), Virginia's portion of I-85 was also the only Interstate Highway in the state with a posted speed limit greater than 65 mph (105 km/h). It was raised from 65 to 70 mph (105 to 113 km/h) on July 1, 2006, by
8820-499: The split with I-40, I-85 continues to Durham , before turning northeastward through Oxford then Henderson toward Virginia . Starting from the Virginia border, the route passes South Hill and McKenney before heading into a large forest. After the forest, I-85 reaches Petersburg and ends at I-95 . The highway is briefly cosigned with US 460 from a few miles west of Petersburg in Dinwiddie County to I-95. I-85 follows
8918-404: The state legislature. In 2004, I-85 was rerouted around Greensboro; and it split with I-40 eight miles (13 km) east of the original departure point. I-40 ran with I-85 along the bypass to the southern/western end and I-40 continued on a new freeway alignment at exit 121 until September 2008, when it was rerouted back to its old alignment through the city. Despite its reroute around Greensboro,
9016-674: The state line in Hart County to meet up with the newly expanded portions just outside of the Atlanta metropolitan area in Jackson County . Interstate Highway [REDACTED] The Dwight D. Eisenhower National System of Interstate and Defense Highways , commonly known as the Interstate Highway System , or the Eisenhower Interstate System , is a network of controlled-access highways that forms part of
9114-496: The terrain between Spartanburg and the North Carolina border is rural in nature but congested to the state line due to its location near Charlotte. In North Carolina, I-85 enters a relatively rural area near Kings Mountain before entering the Gastonia and Charlotte areas. In Charlotte, I-85 bypasses Charlotte Douglas International Airport and turns northeastward just before reaching Uptown Charlotte ; thus, I-85 just bypasses uptown to
9212-490: 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
9310-541: 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
9408-532: Was established by William C. Whitner in 1895 at a hydroelectric plant on the Rocky River , giving the city the name the Electric City. Anderson also became the first city in the world to supply a cotton gin by electricity. In 1895, Anderson Court House was renamed to Anderson. In 1897, Whitner's plant was upgraded with a 10,000-volt generating station at Portman Shoals. Whitner's power plant at Portman Shoals became
9506-422: 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
9604-543: 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
