South Carolina Highway 315 (SC 315) is a 6.1-mile (9.8 km) state highway, serving as a more direct route between Savannah, Georgia and several Lowcountry communities in South Carolina through southern Jasper County. Once the original alignment of S.C. Highway 170 (until 1994) and S.C. Highway 170 Alternate, this route was renumbered in 2010 to clarify conflicting and confusing route alignments. The route, known for the entire length as South Okatie Highway, also serves the unincorporated community of Levy.

The route travels generally in a south to north direction and is a 2-lane road for the entire length. SC 315 begins about five miles north of the Georgia state line at a flashing light intersection with U.S. Highway 17. SC 315 travels in a northeastern direction for two miles before veering toward a more northerly path. The route crosses through the commercial area of Levy before entering additional rural areas. The route terminates upon reaching an intersection with SC 170 west (Freedom Parkway), in which the South Okatie Highway continues straight as SC 170 eastbound, shortly before another similar intersection with S.C. Highway 46.
The entire route is in Levy, Jasper County.
