, the route functions as Memorial Parkway - the main north-to-south freeway through downtown. The road is a freeway with frontage roads and Texas U-Turns, with some stretches with six lanes plus a frontage road exit lane in each direction. In the medical district of Huntsville, the freeway gains US 431 and loses the SR 53 designation. The road widens to ten lanes on the south side of Interstate 565, with the gained lanes used as access lanes for US 72 or I-565. On the north side of I-565, the road once again goes to six lanes and an exit lane, which is carried along its concurrency with US 72. About a mile north of the second junction with US 72, the route loses its frontage roads and reverts to a four-lane divided highway. In general, the route is an important connector between Dothan, Montgomery, and Huntsville, three of the most populous cities in the state.

Kentucky Route 71

In Kentucky, US 231 was originally signed as Kentucky Route 71. KY 71 originally ran from Scottsville to Owensboro. Portions of the original KY 71 in Butler County was rerouted to a bridge over the Green River in the early 1950s, replacing the Morgantown Ferry. In 1952, US 231 replaced the entire alignment of KY 71 in its entirety.Kentucky Transportation Cabinet (1957).
