State Route 520 (SR 520), also known as the South Georgia Parkway, is a 260.1-mile-long (418.6 km) state highway in the southern part of the U.S. state of Georgia. It travels from the Alabama state line at the Chattahoochee River, along the Phenix City, Alabama–Columbus, Georgia line, to Jekyll Island. It has many concurrencies along its path, including U.S. Route 280 (US 280) from the Alabama state line to Richland; US 27 from Columbus to Cusseta; and especially US 82 from Dawson to a point southwest of Brunswick. SR 520 serves as Corridor Z, a high-priority corridor to the Coastal Georgia Regional Development Center and a GRIP (Governor's Road Improvement Program) corridor, but not an Appalachian Regional Development highway, despite its green shield.
