Highway system

Interstate 85 (I-85) is a major Interstate Highway in the Southeastern United States. Its current southern terminus is at an interchange with I-65 in Montgomery, Alabama; its northern terminus interchanges with I-95 in Petersburg, Virginia, near Richmond. It is nominally north–south, but physically mostly northeast–southwest. While most interstates that end in a "5" are cross-country routes, I-85 is mainly a regional route, serving five southeastern states. Major metropolitan areas served by I-85 include the Greater Richmond Region in Virginia, the Research Triangle, Piedmont Triad, and Metrolina regions of North Carolina, Upstate South Carolina, the Atlanta metropolitan area in Georgia, and the Montgomery metropolitan area in Alabama

Route description

I-85 is a route that serves several major locations in the Southeastern United States, stretching from Alabama to Virginia and major metropolitan areas such as Atlanta and Charlotte.

Alabama

I-85 begins as a fork off I-65 in Montgomery. From there, I-85 parallels U.S. Route 80 (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 will soon be rerouted southward just east of Montgomery, where it will intersect with I-65 just south of downtown Montgomery. Future I-685 will be the new designation for the route of current I-85, which leads directly to I-65 in downtown Montgomery.

Georgia

In Georgia, I-85 (unsigned State Route 403) bypasses West Point before coming into the LaGrange area. East of LaGrange, I-85 intersects I-185 which connects to Columbus and Fort Benning. In the Atlanta area, I-85 intersects I-20 and merges with I-75 through the downtown area. North of Atlanta, I-985 provides a link to Gainesville before heading through northeastern Georgia and then crossing into South Carolina. Due to a bridge collapse on March 30, 2017, parts of I-85 in Atlanta were closed.

South Carolina

I-85 provides the major transportation route for the Upstate of South Carolina, linking together the major centers of Greenville and Spartanburg with regional centers of importance. In Spartanburg, BMW has a major manufacturing plant near the highway. In South Carolina, I-85 bypasses Clemson and Anderson on the way to Greenville. Beginning at Anderson, I-85 widens from four to six lanes. Near Powdersville, US 29 joins I-85 and they run concurrently until they cross the Saluda River. I-85 bypasses just south of Greenville, but provides two links into the city via spur routes I-185 and I-385. I-85 also bypasses Greenville–Spartanburg International Airport, which serves the Greenville–Spartanburg metropolitan area. I-85 then bypasses the city of Spartanburg to the north where its original route is now signed as Business Loop 85 and was approved by AASHTO on April 22, 1995.[2] Near mile marker 70, I-85 intersects with I-26. The exits are signed as exits 70A for eastbound traffic and 70B for westbound traffic. North of Spartanburg, I-85 narrows from six lanes back to four lanes and bypasses Gaffney. Much of the terrain between Spartanburg and the North Carolina border is rural in nature.

North Carolina

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 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 Business Loop (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. From Durham, I-85 turns northeastward and heads through Oxford then Henderson toward Virginia.

Virginia

Starting from the Virginia border, drivers will pass 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 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 of Petersburg.

History

See also: Interstate 85 bridge collapse

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 the southern end of the Richmond–Petersburg Turnpike, which was completed in 1958. The tolls were removed in 1992 after I-295 was completed.[3]

Before a 2010 decision to raise the speed limit in the state to 70 miles per hour (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 miles per hour (105 km/h). It was raised from 65 to 70 mph (105 to 113 km/h) on July 1, 2006, by 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, the overall length for I-85 in North Carolina remains the same as before.

Future

An extension of I-85 has been proposed west from Montgomery to interchange with I-20/I-59 just east of the Mississippi–Alabama state line,[4] where it will connect with I-20/I-59 near Cuba, Alabama. This extension will roughly follow the route of US 80, going through or bypassing Selma and Demopolis.[5] The Federal Highway Administration (FHWA) approved the alignment on February 17, 2011, after the American Association of State Highway and Transportation Officials (AASHTO) approved at its Fall 2010 meeting in Biloxi, Mississippi. Also approved was the proposal to re-designate part of existing I-85 south and east of Montgomery to be bypassed as part of the extension of I-85 as I-685. Alabama has permission to co-sign this part of I-85 as I-685 until the new alignment is built.[6] This section is also envisioned by some as part of a proposed I-14.

If this extension were to be completed, I-85 and I-20 would meet each other twice.

I-85 is scheduled to have several new auxiliary routes in the future. I-285 is also planned to follow part of the US 52 freeway from Lexington to Winston-Salem, both in North Carolina. I-785 is currently planned by the North Carolina Department of Transportation to run from Greensboro to Danville, Virginia. The proposed route would follow the current US 29 corridor. There are plans for I-85 from Anderson County to Spartanburg County, South Carolina, to become four to five lanes in each direction including HOV lanes.
