Interstate 85 (I-85) is a major Interstate Highway that travels northeast–southwest in the US 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 North 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 US 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 (The Perimeter). Route description Alabama state line to I-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 metropolitan area. This is the only connection between Columbus and the Interstate Highway System. An stretch between the Alabama line and exit 18 in LaGrange is serving as an environmental and technological testbed for a project called The Ray, a partnership involving federal and state officials, the private sector, academia and philanthropic organizations. Among the projects are a solar-paved roadway, enhanced road striping for autonomous vehicles, and plantings along the right-of-way to improve runoff and possibly serve as a harvestable crop. From I-185 through Atlanta From LaGrange, I-85 heads northeastward toward Atlanta. Before reaching Atlanta, the highway crosses the CSX Transportation A&WP Subdivision twice (in the Grantville area) and passes through the suburbs of Moreland, Newnan, Fairburn, and Union City. The highway then intersects I-285 at its southwest end in College Park. This interchange is one of the most complex interchanges in the country, as I-285 and I-85 stay side
