This segment in the American Auto Trails series travels the breadth of Alabama, from the Georgia State Line and the Talladega National Forest, to the beginnings of the lowlands of Mississippi. U.S. Highway 78 was originally designated as the Bankhead Highway. As progress in transport continues, the old highway will soon be replaced by the new Interstate 22 from Birmingham to Memphis. This guide maintains some of the history of the original road for the future.
