Route description

History

Established in 1922 as an original state highway, it traversed from the Georgia state line to SC 8 in Greenville; connecting McCormick, Abbeville, Due West, Honea Path, Belton, and Williamston. Between 1924-1925, SC 20 was extended north, along Green Avenue, to SC 2/SC 8, replacing a section of SC 8; this would be the longest distance SC 20 ever traveled, reaching over in length.
In 1935, SC 20 was truncated at U.S. Route 29 in Williamston; its old alignment becoming US 29. In 1936, all of SC 20 was fully paved. Around 1937, SC 20 was truncated to its current western terminus in Abbeville, its alignment to the state line replaced by SC 28. In 1956, SC 20 was rerouted between Due West and Belton, replacing SC 257 and some of SC 284; its old alignment, through Honea Path, was replaced by SC 184 and US 178. Also same year, SC 20 was extended back along its old alignment north to a rerouted US 29, just south of Greenville. In 1962, SC 20 was extended into downtown Greenville, along Grove Avenue, ending at US 25, replacing US 29 Business. In 2000, SC 20 was extended to its current northern terminus at Falls Park Drive just shy of US 123, replacing part of US 25 Bus.
