 The Dixie Highway, conceived in 1915, was a north-south route that connected cities in the Midwestern United States with beaches in the South.The Lee Highway was primarily an east-west route that connected Arlington, Virginia, with California.The two routes joined in downtown Knoxville and diverged at the US 70/US 11 split at the Knox-Loudon line, which thus became known as the Dixie-Lee Junction.
