U.S. Route 321
U.S. Route 321 is a spur of U.S. Route 21. It runs for 516.9 miles (831.9 km) from South Carolina to Tennessee. With its northern terminus located in Elizabethton, Tennessee, it has two southern terminus at Hardeeville, South Carolina and Lenoir City, Tennessee. The highway serves different roles in each state: An alternate route to interstates in South Carolina, a major highway in North Carolina, and a scenic route in Tennessee. Because of its unusual "north–south–north" routing, U.S. Route 321 intersects both Interstate 40 and U.S. Route 70 three separate times.
