Metropolitan Atlanta Rapid Transit Authority
The Metropolitan Atlanta Rapid Transit Authority (MARTA /ˈmɑːrtə/) is the principal public transport operator in the Atlanta metropolitan area. Formed in 1971 as strictly a bus system, MARTA operates a network of bus routes linked to a rapid transit system consisting of 48 miles (77 km) of rail track with 38 subway stations. MARTA's rapid transit system is the eighth-largest rapid transit system in the United States by ridership.
MARTA operates almost exclusively in Fulton, Clayton, and DeKalb counties, although they maintain bus service to two destinations in neighboring Cobb County (Six Flags Over Georgia and the Cumberland Transfer Center next to the Cumberland Mall which offers a connection to many CobbLinc bus services), while Doraville station serves portions of Gwinnett County via Ride Gwinnett buses. MARTA also operates MARTA Mobility, a separate paratransit service for disabled customers.
In 2024, the entire system (bus and subway lines) had 65,190,800 rides, or about 205,900 per weekday in the second quarter of 2025.
After 2000, expansion of the MARTA system stalled, after the completion of three new rail stations north of the Interstate 285. In 2016, Atlanta voters approved a historic sales tax increase to raise $2.7 billion over 40 years, in order to significantly expand the MARTA system (dubbed the More MARTA program), including 29 miles of light rail transit, 13 miles of bus rapid transit, arterial rapid transit, transit centers and multiple infill MARTA stations. Since its inception, the More MARTA program has been criticized for slow progress, delays, and reversals on executing its list of expansion projects.
MARTA was proposed as a rapid transit agency for DeKalb, Fulton, Clayton, Gwinnett, and Cobb counties. These were the five original counties in the Atlanta metropolitan area, and to this day are the five largest counties in the region and state. MARTA was formed by an act of the Georgia General Assembly in 1965. In the same year, four of the five metropolitan area counties (Clayton, DeKalb, Fulton, and Gwinnett) and the City of Atlanta passed a referendum authorizing participation in the system, but the referendum failed in Cobb.
Although a 1968 referendum to fund MARTA failed, in 1971, voters in Fulton and DeKalb counties successfully passed a 1% sales tax increase to pay for MARTA operations, while Clayton and Gwinnett counties overwhelmingly rejected the tax in the referendum. Gwinnett County remains outside of the MARTA system. In November 2014, however, Clayton County voters passed a 1% sales tax to join the MARTA system, reversing its 1971 decision.
Also in 1971, the agency agreed to purchase the existing, bus-only Atlanta Transit Company; the sale of the company closed on February 17, 1972, giving the agency control over all public transit in the immediate Atlanta area.
Construction began on MARTA's heavy rail system in 1975, with the first rail service commencing on June 30, 1979. The system has since built most of the proposed rail lines, as well as stations in Dunwoody, Sandy Springs, and North Springs, which were not included in the original plan. The missing rail segments from the original plan include a Tucker-North DeKalb line with service to Emory University and North Druid Hills, a Northwest line with service to Brookwood and Northside Drive, the extension of the West line to Brownlee-Boulder Park near Fairburn Road, the extension of the Proctor Creek line to West Highlands, and a branch off the south line to Hapeville and Clayton County.
