Route descriptionEdit

SC 3 begins at an intersection with U.S. Route 278 (US 278) in rural Jasper County. The route heads northwest, and crosses into Hampton County. Continuing northwest, it intersects US 601 before a brief concurrency with US 321 in Estill. The highway continues northwest into Allendale County. After crossing into the county, SC 3 turns north and intersects US 301 approximately seven miles (11 km) southwest of Allendale. The route continues north until it enters Barnwell County.[1]

Just after the county line, SC 3 turns northeast and intersects US 278 just before the Salkehatchie River, approximately two miles (3.2 km) south of Barnwell. US 278/SC 3 form a concurrency into Barnwell. In town, SC 3 splits off to the northeast, intersecting SC 64 and SC 70. The highway heads northeast to Blackville, where it crosses US 78. It then heads northward, crossing the South Fork of the Edisto River, where it enters Orangeburg County. Just before the river, the route begins its last northeastern orientation, passing just east of Springfield, intersecting SC 3 Business and SC 4. SC 3 heads northeast, skirting the Aiken County line, before entering Lexington County. Approximately seven miles (11 km) northeast of the county line, SC 3 meets its northern terminus, at its second intersection with US 321 in the southern part of Swansea.[1]


A previous version of SC 3 existed as an original state route, running from Columbia to Sumter, Florence, and Mullins before crossing the North Carolina state line where US 76 does today. In 1927, the route was renumbered as various US highways.

The current version of SC 3 was established in 1928 as a renumbering of the closing SC 1. It originally ran from Allendale to Dixiana.

In 1938, the northern terminus was extended about 3 miles north to West Columbia. In 1939, however, it was pushed back south to Dixiana. In that same year, the southern terminus was extended southward a short distance to Barton. In 1948, the northern terminus was again pushed back, this time to Swansea. The southern terminus was also pushed north back to Allendale. Five years later, in 1953, the southern terminus was moved up north to Barnwell.

In the early 1960s, the northern terminus was extended up to Dixiana once again. In 1962, the highway was extended southward to US 321 in southwest Allendale County. In 1971, the northern terminus was once again moved back south to Swansea. In 1972, the southern terminus was moved southeast to Grays, giving us the current SC 3 routing.[2]
