South Carolina Highway 215

South Carolina Highway 215 (SC 215) is a 96.330 mi primary state highway in the U.S. state of South Carolina. It serves as an alternate route to Union from either Columbia or Spartanburg.

Route description
SC 215 is a two-lane rural highway that traverses for 95.7 mi from Columbia to Spartanburg; connecting Jenkinsville, Carlisle, Union, and Roebuck.

History
It was established in 1928 as a renumbering of SC 121 and SC 161. It originally traveled from U.S. Route 78 (US 78) in Aiken, northeast through Wagener, Pelion, Edmund, and West Columbia. Through Columbia, in a concurrency with US 1/US 21/SC 2, it heads northwest through Jenkinsville, Carlisle, ending at US 176/SC 92 in Union.

In 1939, the entire route was paved. In 1948, SC 215 was rerouted to approach Union from the south, its old route through Monarch Mill being replaced by SC 92 (today SC 49-SC 215 Connector). In 1949, SC 215 was extended north to SC 56, in Pauline; a year later, it was extended north again to US 221 in Roebuck.

By 1958, SC 215 was rerouted in Columbia along Assembly Street to Blossom Street before heading west across the Saluda River in concurrency with US 21/US 176/US 321. By 1964, SC 215 was extended north from Roebuck to its current northern terminus at SC 295/SC 296 in Spartanburg; it replaced SC 295, and brought SC 215 to its longest routing.

Between 1974 and 1977, SC 215 south of Eau Claire, in Columbia, was removed. The old alignment between Aiken to Cayce became SC 302, while in Columbia US 21/US 321 remained.

Union connector route
South Carolina Highway 215 Connector (SC 215 Conn.) is a brief 0.120 mi stub of Pinckney Street, between the SC 215 mainline and SC 18. It serves as a turn-off onto SC 18, from SC 215, without taking the right turn at the intersection immediately afterwards; as a hidden designation, signage only identifies it as SC 18 north (no south).
