SC 284 begins at an
intersection with
SC 81 southeast of
Lowndesville, within
Abbeville County, where the roadway continues as Tom Young Bridge Road. It travels to the east and immediately crosses Gill Creek. It curves to the northeast and intersects
SC 71. Then, it travels along the southeastern edge of
Antreville. Just after it leaves the
city limits, it intersects
SC 28/
SC 184. The three highways travel
concurrently to the northwest. Almost immediately, they enter Antreville, where SC 184 departs to the northwest. SC 28/SC 284 leaves the city limits and split. SC 28 enters
Anderson County and has intersections with the western terminus of
SC 201 (Level Land Road) and then
SC 185 (Due West Highway). Farther to the northeast, it meets its eastern terminus, an intersection with
SC 20 in
Craytonville.[3]
