Transportation
Perimeter Center is located at the interchange of two major freeways: the north/south Georgia 400, and the "top end" of the Interstate 285 beltway, "the Perimeter" for which the Mall and the area around it were named.
Perimeter Center is connected to Buckhead, Midtown and downtown Atlanta via heavy-rail rapid transit. There are three MARTA train stations in the area. Opened in June 1996, Dunwoody station swings out east of the county line to serve the mall at the southwest corner of its parking lot. Going back west of the line is Sandy Springs station, located under one of the busiest intersections in the area. North of there is the North Springs station next to Georgia 400, currently the end of the north line. A further extension that has been studied but not planned is up the 400 corridor to Alpharetta, the location of another edge city about 10 miles (16 km) or 16 kilometers to the north-northeast. The Atlanta Regional Commission has this in long-term plans, along with an east/west light rail route along the Perimeter, going west to Cumberland (about 9 miles (14 km) or 15 kilometers west-southwest), and east to Doraville to meet the existing northeast MARTA line.
