The western terminus of the route is near Red Bay at the Mississippi state line, where it continues as Mississippi Highway 76 (MS 76). The eastern terminus of the route is near the junction with SR 67 at Decatur, where it continues for 2 miles as Moulton Street. Moulton Street (without SR 24) ends east of US 31. The route is one of several segments that comprises Corridor V of the Appalachian Development Highway System. Once completed, Corridor V will provide a continuous route between Batesville, Mississippi and Chattanooga, Tennessee.
