Interstate 20 (I-20) is the main east–west Interstate Highway in the state of South Carolina, linking the state with important transportation and business hubs to the north, west, and south, including Atlanta, Georgia; Charlotte, North Carolina (via I-77); Savannah, Georgia (via I-95); and Washington, D.C. (via I-95). I-20 travels 141.51 miles (227.74 km) west to east, from the Georgia state line at North Augusta, through Columbia, to end at I-95 in Florence. Past I-95, the roadway continues as Interstate 20 Business (I-20 Bus.) for about two miles (3.2 km) to U.S. Route 76 (US 76), which goes to downtown Florence.

The Interstate parallels US 1 closely from the state line to Camden where US 1 diverts away from the route and head northeast towards North Carolina while I-20 turns and heads eastward towards Florence.
