SC 283 begins at an
intersection with
U.S. Route 221 (US 221)/
SC 28 (Main Street) in
Plum Branch, within McCormick County, where the roadway continues as Collier Street. It travels to the east and nearly immediately curves to the east-northeast before leaving the
city limits. The highway curves back to the east and crosses over Stevens Creek. SC 283 goes back to the northeast and enters
Whitetown. Just past the intersection with Upper Mill Road the highway enters
Sumter National Forest. After it starts heading to the east-southeast, it crosses over Byrd Creek. After a crossing of Wine Creek, it crosses over Turkey Creek and enters
Edgefield County. Just to the east of an intersection with North Martintown Road, which is south-southwest of
Cleora, the highway leaves the national forest. Farther to the east, it meets its eastern terminus, an intersection with
US 25, at a point northwest of
Edgefield.[3]
