History
SC 18 was established in 1938 as a renumbering of SC 111, from U.S. Route 29 (US 29) in Gaffney, to the North Carolina state line. In 1940, SC 18 was extended south along new primary routing to SC 9 in Pacolet.[2] In 1942, it was extended again along new primary routing to SC 56 south of Glenn Springs.[3] In 1960-1961, SC 18 was rerouted at Gaffney to US 176/SC 9 in Jonesville, replacing part of SC 11; its old alignment became part of SC 150.[4][5] In 1989, SC 18 was extended to its current western terminus at US 176/SC 215, replacing part of US 176 and all of US 176 Bus.[6]
The first SC 18 was an original state route, established in 1922 between SC 17 in Westminster and SC 20 in Abbeville. In 1938, most of SC 18 was renumbered as part of SC 24.
