American Auto Trail-Dixie Highway (Pittsburg to Mount Vernon KY)
This travel route follows a very historical path thorough a portion of southeastern Kentucky. One of the key routes of the pioneers moving west through the Appalachians, it followed even earlier paths of the buffalo and Native Americans.
As time passed, the route was followed by the Louisville & Nashville Railroad in the late 1800s, the Dixie Highway auto trail in the early 1920s, the Federal Highway System in the late 1920s, and the Interstate Highway System in the 1960s.
