SC 462 is a rural two-lane highway that makes a half-circle in Jasper County, broken into five named sections of road.

The first section named Gillison Branch Road begins at the intersection of U.S. Route 321 (US 321) in Robertville, goes northeast to US 601 in Pineland, then east connecting with US 278 in Gillisonville.

The fourth section named Coosaw Scenic Drive connects Coosawhatchie with SC 336 in Old House.

[6] Between 1962 and 1964, SC 462 was extended west again over existing secondary roads to its current western terminus at Robertville; this brought the highway's maximum length to 46 miles (74 km).

Between 1965 and 1967, SC 462 east was truncated to US 278 in Old House, its old alignment south to near Bluffton becoming part of US 278.
