Interstate 85 (I-85) is a major Interstate Highway that travels northeast-to-southwest in the U.S. state of Georgia. It enters the state at the Alabama state line near West Point, and Lanett, Alabama, traveling through the Atlanta metropolitan area and to the South Carolina state line, where it crosses the Savannah River near Lake Hartwell. I-85 connects northern Georgia with Montgomery, Alabama, to the southwest, and with South Carolina, North Carolina, and Virginia to the northeast. Within Georgia, I-85 is also designated as the unsigned State Route 403 (SR 403).
I-85 in Georgia usually travels roughly parallel with the route of U.S. Route 29 (US 29). However, from Atlanta northeast to South Carolina, I-85 ventures away from that route, traveling about halfway between US 29 and the combination of US 23 and US 123.
Within the City of Atlanta, I-85 has a concurrency with I-75 known as the "Downtown Connector". After splitting from Downtown Connector, it is known as Northeast Expressway until its junction with I-285 (Atlanta's perimeter).

Route description
Alabama state line to Interstate 185
I-85 enters the state of Georgia from Alabama via twin bridges over the Chattahoochee River, and then it immediately skirts the town of West Point, with Kia's multibillion-dollar plant located adjacent to the freeway just east of West Point. After leaving West Point, I-85 enters the LaGrange area, the first large town in Georgia on its route to the northeast. Northeast of LaGrange, I-85 has an interchange with the long spur freeway, I-185, to the Columbus, Georgia Metropolitan Area. This is the only connection between Columbus and the Interstate Highway System.
From Interstate 185 through Atlanta
From LaGrange, I-85 heads northeastward towards Atlanta. Before reaching Atlanta, the highway runs through a recently widened stretch that includes six to eight lanes between exits 35 and 77, passing near the suburbs of Moreland, Newnan, Fairburn, Union City, College Park and East Point as well as intersecting I-285 at its southwest end and providing access to Hartsfield-Jackson Atlanta International Airport. I-85 then runs along the northwestern boundary of the airport, providing access to the domestic terminal. (This airport is bounded on all sides by I-85, I-75, and I-285, all of which provide highway access to the airport.)
At the southwestern edge of Atlanta's city limits, I-85 merges with I-75 to form the Downtown Connector, which is 12 to 14 lanes wide. At the southern edge of downtown Atlanta, this freeway has an interchange with the major east-west Interstate Highway, I-20. The two freeways then skirt the eastern edge of downtown, running due north, passing through the Georgia Tech campus and the Atlantic Station section of Atlanta before the two highways split, with I-75 exits via the right three lanes and then heads northwest while I-85 uses the left three lanes and then heads northeast.
Atlanta to South Carolina state line
Heading northbound after the Brookwood Interchange with I-75, I-85 is routed along a ten lane wide viaduct from the Buford Highway Connector (exit 86) to State Route 400 (SR 400, exit 87). Continuing northeast of Atlanta, I-85 continues through the northeastern suburbs, bypassing Chamblee and Doraville, where there is another intersection with I-285 (nicknamed Spaghetti Junction). The Interstate then travels through the northeastern suburbs of Atlanta, including Lilburn, Duluth, Lawrenceville. The Interstate has freeway interchanges with SR 316 in Duluth and I-985 in Suwanee, which provides a link to Gainesville. I-85 then leaves the Atlanta area, continuing to travel through rural northeast Georgia. At Lake Hartwell--which was formed by the damming of the Savannah River--I-85 crosses into South Carolina.
Express lanes
I-85 has the first express lanes in Georgia, located in Gwinnett and DeKalb counties; they were originally HOV lanes. From Chamblee-Tucker Road (exit 94) to Old Peachtree Road (exit 109), travelers that utilize the converted 15.5-mile (24.9 km) lanes will be charged a toll varying from 10 to 90 cents per mile (6.2-55.9 ¢/km), depending on traffic conditions and usage. Though not signed on the freeway, they are HOT lanes, which means registered transport vehicles, carpools with three or more occupants, motorcycles, and buses are exempt from toll charges as long as they are registered as such. Tolls are collected using an electronic toll collection system. All travelers that use the lane must have a Peach Pass sticker to avoid fines. Starting in November 2014, SunPass (Florida) and NC Quick Pass (North Carolina) are interoperable with Peach Pass, allowing motorists with those transponders to use the express lanes.
Funds generated from the express lanes will be used to defray the costs of construction, operations and maintenance of the lanes. Long term revenue allocation is being studied and a decision about future excess revenues will be made later in the project process.
Proponents for the express lanes say it is to provide commuters with a more reliable, free-flow commute option; complement the state's multi-modal approach to managing traffic demand; and establish the vision for a future system of HOT lanes in the region. Detractors point out that existing infrastructure was reused for the express lanes and that commute times on the non-paying travel lanes have doubled since implementation.
History
Originally constructed as a four- to six-lane expressway in the 1950s, the stretch of I-85 between the southern merge with I-75 and North Druid Hills Road was reconstructed as part of the Georgia Department of Transportation's Freeing the Freeways program. This project included rebuilding all overpasses, new HOV-ready ramps (with the system implemented in 1996), and a widening of freeway capacity. Concurrent with this project was the construction of the Civic Center MARTA Station as part of the West Peachtree Street overpass, which opened in December 1981.
The 30-mile (48 km) section between LaGrange and Newnan was incomplete for a much-longer time that the rest of I-85 in Georgia and required a two-lane detour on Hwy 27 & Hwy 29 between those cities. The northern section between Newnan and Grantville was completed first, then the stretch further south to LaGrange was completed in 1977.
The portion of the highway from the Buford Highway Connector to SR 400 was constructed during the early 1980s, and was designed as a replacement for the original four-lane routing of I-85 (now SR 13). In addition, the new viaduct was designed to accommodate connections to the SR 400 tollway (then in planning), HOV lanes, and a bridge carrying the MARTA North Line (then under construction).
Until 2000, the state of Georgia used the sequential interchange numbering system on all of its Interstate Highways. The first exit on each highway would begin with the number 1 and increase numerically with each exit. In 2000, the Georgia Department of Transportation switched to a mileage-based exit system, in which the exit number corresponded to the nearest milepost.
On October 1, 2011, GDOT converted the 16.0-mile (25.7 km) HOV lanes in Northern Atlanta into express/HOT lanes.
From Atlanta, I-85 north was originally slated to be built through the city of Athens to provide an easy link between the capital city and the University of Georgia. However, then-Gov. Ernest Vandiver worked to make sure the highway traversed his home county of Franklin, a stretch that now bears his name. At the time, he promised equivalent access for Athens and Gainesville. It was not until the completion of SR 316 in the 1990s that there was finally a relatively quick, multi-lane expressway connecting Athens and Atlanta, (US 78 is also multi-lane between Athens and Atlanta but it is not expressway-grade) although SR 316 still is largely at-grade.
On March 30, 2017, a fire started at approximately 6:15 p.m. in a storage area under the highway along Piedmont Road in the Piedmont Heights area of Midtown Atlanta. This caused the collapse of a 100-foot (30 m) section of I-85 northbound. The highway in both directions needed to be demolished and replaced. According to the Georgia Department of Transportation, the work was completed ahead of schedule. Both the north and south bound portions of the interstate were open by May 15, 2017, a month ahead of expectations.
Exit list
Auxiliary routes
There are three auxiliary Interstate Highways of I-85 within Georgia and a fourth that was proposed, and then cancelled. I-185 is a spur from Lagrange to Columbus. It mainly provides a freeway between the Columbus and Atlanta metropolitan areas. I-285 is a heavily traveled beltway around Atlanta, which helps I-75 and I-85 drivers to bypass the city. I-485 was a short freeway in Atlanta (now Freedom Parkway) that was incomplete for many years and then decommissioned due to local opposition. Also, I-985 is a spur from I-85 to Gainesville.
