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.).

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.

It is known as Crest Road, is concurrent with SC 23 Truck, and is an unsigned highway.

The connector begins at an intersection with the SC 430 mainline (also known as Crest Road).
