South Carolina Highway 19 (SC 19) is a primary state highway in the U.S. state of South Carolina. It connects Aiken directly with the Savannah River Site and Edgefield (via US 25).
SC 19 operates as arterial four-lane highway from Aiken to the Savannah River Site; to its north, it is a two-lane rural highway to Trenton, where it connects with US 25 and SC 121. In Aiken's downtown area, SC 19 is signed, northbound along Chesterfield Street and Richland Avenue (on state maps, it is officially SC 19 Conn); while SC 19 southbound travels along Laurens Street/Park Avenue onto Chesterfield Street.
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 (again) to SC 28, north of Ellenton.
