South Carolina Highway 12 (SC 12) is a state highway in the U.S. state of South Carolina. It serves Columbia and areas to its east. It serves as a parallel route to Interstate 20 (I-20) for much of its length.

Route description[edit]

The route begins as a four-lane highway, splitting from U.S. Highway 1 (US 1) where it is known as Jarvis Klapman Boulevard. It crosses the Congaree River on the Jefferson Davis McMahan Bridge headed into downtown Columbia. For a 0.6-mile (0.97 km) stretch in Columbia, the highway splits into two parallel one-way streets separated by a city block, Taylor Street and Hampton Street (the route keeps the name Taylor Street as it continues east). After its intersection with US 1, the road changes its name to Forest Drive. After a sharp turn, the road is known as Percival Road, then Fort Jackson Road. North and east of Columbia, the route runs next to Fort Jackson and parallel to both I-77 and I-20. The route traverses through rural land before reaching its terminus at US 601 near the I-20 interchange.[2]


Previous designations[edit]

There have been two previous versions of SC 12. The first version ran from the 5th Street Bridge at the Georgia-South Carolina state line near Augusta, Georgia, to Aiken, Leesville, and Lexington, South Carolina before ending in West Columbia. Today, this route is marked as US 1 from the state line to West Columbia, which was assigned the route in 1927. SC 12 was dropped from the route in 1928, the year afterwards.

The second former route of SC 12 was established between 1928 and 1931. The route ran from what is now US 521 between Lancaster and Fort Mill for two miles (3.2 km) to the North Carolina state line near Waxhaw, North Carolina, at what was then NC 25. In 1934, North Carolina changed NC 25 to NC 75, and South Carolina renumbered SC 12 to SC 75 four years later, in 1938.[1]
