SC 430 begins at an
intersection with
SC 23 just northeast of Edgefield. This is also the northern terminus of
SC 23 Truck, which begins
concurrent with SC 430. The two highways head northwest, cutting across the northeast part of the city. They then intersect Meeting Street, which leads to the northbound lanes of
U.S. Route 25 Business (US 25 Bus.). At this intersection, SC 23 Truck continues to the northwest, concurrent with the
unsigned designation of
SC 430 Conn. (which take on the Crest Road name). SC 430 turns right and heads to the north-northeast until it meets its northern terminus, at an intersection with
US 378 on the southeastern edge of Sumter National Forest, in a rural part of the county. SC 430 is not part of the
National Highway System, a system of roadways important to the nation's economy, defense, and mobility. ==History==
