Bankhead Highway Visitor Center – The Bankhead Highway, which opened in 1919 and ran from Washington D.C. to San Diego, was the nation's first all-weather transcontinental highway. It passes through Franklin County and serves as Mount Vernon's Main Street and follows an early Indian trading route known as the Choctaw Trail. By 1930 it was renumbered as U. S. No. 1 and was called "The Broadway of America." The Bankhead Highway Route was changed in 1937 and follows present U. S. Hwy 67.
