GA 400 Corridor Details 

The GA 400 Corridor Transit Initiative: Alternatives Analysis involves investigating the need for high-capacity transit connections between the Perimeter Center area near the interchange of I-285 and GA 400 in the City of Sandy Springs and McGinnis Ferry Road in northern Fulton County.  The corridor draws commuters from throughout the region and is the origin point for many commuter trips bound for central Atlanta, Gwinnett, and  Cobb Counties.  These conditions have created high levels of traffic congestion on GA 400 and the few east-west arterials which cross the expressway.

The study will result in the identification of a specific alignment and technology or locally preferred alternative (LPA) that best meets the transit needs for the corridor.  Once this selection has been made an environmental impact statement (EIS) will be developed followed by engineering and design activities.
