History edit
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.[4] In 1942, it was extended again along new primary routing to SC 56 south of Glenn Springs.[5] 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.[6][7] 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.[8]

The first SC 18 was an original state highway, established in 1922 between SC 20 in Abbeville northwest to Anderson and then northwest to SC 17 in Westminster. The next year, it was extended north-northeast to SC 2 in Walhalla. Two or three years later, its Westminster–Walhalla segment was eliminated, and it was routed from Westminster to the Georgia state line northwest of Long Creek. Its former path was redesignated as SC 183. In 1933, its western terminus was truncated to Westminster, to an intersection with US 76 and SC 13. Its former path was redesignated as part of US 76. In 1938, SC 18 was redesignated as part of SC 28 from Abbeville to Anderson and SC 24 from Anderson to Westminster.
