State route 280 (SR 280) is a generally south-to-north state highway located in the Atlanta metropolitan area in the west-central part of the U.S. state of Georgia. It runs from Georgia 139 in western Atlanta to Interstate 75 (I-75) in Marietta. The road has the odd shape of a shepherd's hook.

Route description[edit]

Georgia 280 begins in western Atlanta at an intersection with Georgia 139 (Martin Luther King Jr. Drive), where the roadway continues as Hamilton E. Holmes Drive. The route travels north along Hamilton E. Holmes Drive and James Jackson Parkway, meeting I-20 at an interchange, then continues north to an intersection with U.S. 78/U.S. 278/Georgia 8 (Donald Lee Hollowell Parkway). The route then continues on to the Atlanta neighborhood of Riverside, where the route curves to the northwest. It then crosses the Chattahoochee River into Cobb County, where it is known as South Cobb Drive, and continues northwest until its an interchange with I-285 in Smyrna, continuing through western portions of Smyrna.

In Fair Oaks, the route has a short concurrency with Georgia 5 at Austell Road. After arcing to the northeast past Chattahoochee Technical College's main campus, Georgia 5 departs the concurrency at Pearl Street, a minor side street, instead of going directly onto Atlanta Road. (It is unclear why this arbitrary routing was chosen, since it could simply skip 280 and go directly from Austell Road to Atlanta Road – itself an arbitrary rerouting from the original route through Powder Springs to an equally congested route through Austell.) Georgia 280 then curves to the southeast, passing through Dobbins Air Reserve Base, and then to the east to an intersection with U.S. 41/Georgia 3. There, it becomes known as Delk Road. The route heads nearly due east until it meets its northern terminus at I-75, mile 261 (former exit 111) in Marietta, though the roadway continues east as Delk Road. The road originally ended at Powers Ferry Road, but was extended a block eastward around 1989 to Terrell Mill Road, after a county sales tax was passed to fund it and other projects.

The route has at least four lanes for its entire length, and has six lanes in Marietta and between U.S. 41 and I-75.[citation needed]

Georgia 280 is a major urban arterial, with portions of the route seeing an average annual daily traffic (AADT) of over 30,000 vehicles, especially around Dobbins Air Reserve Base. It serves as a major commuter route in southern Cobb County and for those traveling to Dobbins Air Reserve Base and the adjacent Lockheed Martin plant in Marietta.

In 2006, the Chattahoochee River bridge was rated one of the worst in the state, according to the Federal Highway Administration (FHWA). The bridge was rebuilt in 2008 by Georgia DOT.


In northwest Atlanta, Georgia 280 was known as Hightower Road, but was renamed to honor Hamilton E. Holmes.[citation needed] The Hightower MARTA station was likewise renamed as Hamilton E. Holmes station.
