History

SC 19 is an original state highway, established in 1922. Its original routing was from SC 2 in Newberry, north through Whitmire, Union, Spartanburg, Inman and Landrum, to the North Carolina state line continuing as NC 19. In 1923, it was extended south on new primary routing, through Saluda, to SC 21/SC 27 in Trenton. In 1927, US 176 was assigned to SC 19 from Newberry to the North Carolina state line; the following year it was removed from the overlap. Also in 1928, SC 19 was extended south, replacing part of SC 27 to US 1/US 78 in Aiken. In 1929 or 1930, SC 19 was extended south to SC 28 north of Ellenton.
Around 1952, the Savannah River Site was established; which removed of highway in what is now a restricted area. By 1955, SC 19 was widened to four-lanes between the Savannah River Site and Aiken. In 1964, SC 19 was truncated to its current northern terminus at Trenton; its routing north to Saluda was replaced by SC 121.
