Marta

Buses

MARTA's bus system serves a wider area than the rail system, covering areas in Fulton, Clayton and DeKalb counties such as the cities of Roswell and Alpharetta in North Fulton, along with South DeKalb. On April 18, 2026, MARTA launched the NextGen Bus Network, the system's first comprehensive route redesign since the 1970s, consolidating the system from 113 routes to 81 while more than tripling the number of corridors with all-day 15-minute-or-better frequency, from five to 17. As of fiscal year 2024, MARTA operated 397 buses in maximum service, according to Federal Transit Administration data. MARTA has one bus route providing limited service into Cobb County, Route 12, which connects Midtown to the Cumberland Transfer Center. MARTA shuttle service is available to Six Flags Over Georgia during the park's summer season.
