Georgia State Routes Former

State Route 520 (SR 520), also known as the South Georgia Parkway, is a state route in the southern part of the state of Georgia.

Its western terminus occurs at the Alabama state line on a bridge over the Chattahoochee River that also carries U.S. Route 280. SR 520 becomes unsigned SR 38 upon crossing the state line. The route follows US 280 southeast to Richland, then runs independently to Dawson. The route joins US 82 there and overlaps it throughout much of southern Georgia all the way to I-95. SR 520 then runs concurrently with US 17/SR 25 for a few miles before departing and proceeding to Jekyll Island, where it ends at Beach View Drive.

While not part of the Appalachian Development Highway System, SR 520 is nevertheless designated as Corridor Z. To emphasize the special designation, SR 520 route markers have a green background and numbers as opposed to black, which is normally used on state Route markers. Some markers also feature the small abbreviation "CORR Z" near the top of the state outline, though this practice is being phased out.[citation needed]
