State Route 28 (SR 28) is the Georgia segments of a multi-state Route 28 that, in Georgia, runs from eastern Richmond County northwestward to northeastern Columbia. There is also a short segment in northeastern Rabun County. The two segments in Georgia total 25.55 miles (41.12 km).

The southern segment of the route begins at the Savannah River at the South Carolina state line in southeastern Augusta. It intersects I-520 approximately 1 mile (1.6 km) from the state line. The route, then continues northwest into downtown Augusta as Broad Street and Greene Street, reaching interchanges with US 1/US 25/US 78/US 278/SR 10/SR 121 and US 25 BUS in downtown, and I-20 and SR 104 north of downtown. Still traveling northwest, the route enters Columbia County. The route then crosses the Savannah River again, re-entering South Carolina.

The northern segment cuts across the northeast corner of Rabun County, Georgia connecting North Carolina and South Carolina. It passes through the Pine Mountain community in eastern Rabun County. The southern end of this segment, at the bridge over the Chattooga River on the South Carolina state line, is a popular put-in and take-out point for kayakers and whitewater rafters.[citation needed]
