Project Overview 

MARTA Rapid B-Line (Southlake) will bring faster, more reliable bus service to Clayton County. The 13.6-mile bus rapid transit (BRT) route will connect Hartsfield-Jackson Atlanta International Airport to the Southlake area, making it easier to reach jobs, services, shopping, and other destinations along the corridor. The project will support better travel options, improve access to key places, and help strengthen economic growth in the area.
