U.S. Route 21 or U.S. Highway 21 (US 21) is a north–south United States Numbered Highway in the Southeastern United States, spanning 394 miles (634 km) from Hunting Island State Park, South Carolina, to Wytheville, Virginia. Despite the "1" indicating that it is a major north–south highway, US 21 only travels through three states and is no longer a cross-country route as it has been replaced with I-77 in both Ohio and West Virginia. It also has the second-shortest length of all of the major north–south routes, just behind US 91. The route travels through the states of South Carolina, North Carolina, and Virginia. It also connects through major Southeastern cities such as Columbia, South Carolina, and Charlotte, North Carolina. The northern portion of the road travels parallel to I-77 in northern South Carolina and North Carolina. The road also has three interchanges with I-26 in Lexington and Calhoun counties in South Carolina.
