The current routing of SC 702 was created by 1952 and has remained unchanged since. It was originally established in 1940 as a loop off SC 7west of Greenwood. By 1942, SC 702 was extendedeast through Greenwood to SC 246, then southeast along the route it shares today to SC 39 north of Saluda. In 1948, SC 702 was reduced back to its original routing as a loop highway. In 1950, what remained of SC 702 became part of SC 72. The roads between the loop and its current alignment: Cambridge Avenue, SiloamChurch Road and Vines Road, has remained as secondary roads.
