U.S. 421 begins in Michigan City, Ind., and ends at Fort Fisher, south of Kure Beach.

Along the way, the highway passes through Kentucky, Tennessee, Virginia and western North Carolina.

When first built in the early 1930s, U.S. 421 began in Boone and terminated in Greensboro, according to information on the website USends.com.

By the mid-1930s, the highway had been extended to Cumberland Gap, Va. After construction of the Cumberland Gap Tunnel was completed, the terminus of U.S. 421 was relocated in 1950 about 40 miles east to Bristol, Tenn.

Bedford, Ky., was the northern terminus by the early 1950s, quickly followed by Michigan City, where it remains today.
