The Dixie Highway Association met in 1915 to plan a highway route from Chicago to Miami, later extending it to Canada. Tennessee's Dixie Highway: The Cline Postcards traces the path of the Dixie Highway along its western and eastern branches through the state, showcasing the works of photographers Walter M. Cline Sr. and Jr. The journey begins in Nashville and travels south to Chattanooga. Chattanooga served as both headquarters of the Dixie Highway Association and home to the Cline family. Moving north of the city, the eastern route arrives near the Kentucky border in Jellico. Many of the places that fascinated the Clines during the 1930s and 1940s are still popular destinations today.
