The route of SC 68 travels generally in a northwest to southeast direction, beginning at a junction with U.S. Highway 278 (US 278 just south of Varnville. The highway travels in a nearly straight line for its entire length, paralleling the Port Royal and Augusta Railway (today the CSX Augusta Subdivision). The roadway passes through the small hamlet of Early Branch before widening to a four-lane configuration about one mile (1.6 km) north of the I-95 junction. Passing underneath I-95, SC 68 returns to a two-lane configuration as it enters Yemassee before terminating at an intersection with US 17 Alternate and US 21.[2]
