U.S. Route 231 - Route Description - Alabama

Alabama

In Alabama, US 231 is paired with unsigned State Route 53 from Huntsville to Dothan. From the Tennessee state line to Huntsville, and from Dothan to the Florida state line, this route is paired with unsigned State Route 1. From the Tennessee line to Huntsville, US 231 pairs with US 431. In Harpersville US 231 follows US 280 east. Just south of Sylacauga US 231 branches off southward again as its own route to Montgomery. US 231 is referred to as Memorial Parkway throughout Huntsville and Madison County.

In Dothan, there is a spur of US 231, Business US 231, which runs north–south directly through downtown Dothan from US 231 at the Ross Clark Circle. Until the 1980s, there were several other Business US 231 designations near and through the towns of Brundidge, Troy, and Montgomery.

Also, until the 1980s, there was an Alternate US-231 which ran north from the intersection/interchange with US-280 just south of Sylacauga, Alabama, northeastward through Sylacauga, Winterboro, and onto Talladega, Alabama. This routing was co-signed with Alabama State Route 21. From Talladega, Alternate US-231 ran northward co-signed with Alabama State Route 77 to just south of Lincoln, Alabama. There for a one-mile segment, Alternate US 231 ran along its own route just west of and parallel to Alabama State Route 77 until it reached an intersection with US-78 in the center of the small town of Lincoln, Alabama. There Alternate US-231 turned westward for nine miles co-signed with US-78 into Pell City, Alabama. There Alternate US-231 rejoined US-231. Alternate US-231 was decommissioned in the early 1980s.

Much of US 231 throughout north and central Alabama is a two-lane route. However, from just north of Wetumpka, Alabama, southward to the Florida state line the route is four lanes. Also, the section from the Tennessee-Alabama state line southward to Arab, AL, is also four lanes. In north and central Alabama, US 231 traverses the SW to NE ridgelines of the Appalachian Mountains as well as crossing several river valleys which provide some excellent natural scenery. Most of the four-lane segment south of Wetumpka, Alabama, to the Florida state line is along gently rolling countryside from several river and stream valleys onto the Gulf Coastal Plain.
