The highway connects North Hartsville and Chesterfield, via Patrick.

Then, it crosses over Cedar Creek, where it enters Chesterfield County.

SC 102 curves to the north-northwest for a short while before traveling in a fairly northerly direction.

Just before entering Patrick, the highway goes through Sand Hills State Forest.

It winds its way through rural areas of the county until it meets its northern terminus, an intersection with SC 9 (East Boulevard) in Chesterfield, where the roadway continues as South Craig Street.
