Route description

From its origin south of Scottsboro, State Route 40 travels across the base of Lookout Mountain. The narrow, twisty roadway continues until the route reaches Dutton in western DeKalb County. East of Dutton, the roadway has fewer curves as it continues across the county. While State Route 40 does not directly intersect Interstate 59, there is direct access to I-59 via State Route 117 approximately one mile southeast of the eastern terminus of the route.
