U.S. Highway 431 (US-431), internally designated by the Alabama Department of Transportation as State Route 1 (SR-1), is a major north-south state highway across the eastern part of the U.S. state of Alabama. Although US-431's south end is in Dothan, SR-1 continues south for about 13 miles (21 km) along US-231 to the Florida state line.

Route description

State Route 1 is primarily the unsigned partner route assigned to U.S. Highway 431. The two routes are co-aligned from the southern terminus of US-431 at Dothan to the Tennessee state line. South of Dothan, State Route 1 is assigned to U.S. Highway 231. At Huntsville, US-231 and US-431 junction again, and State Route 1 is partnered with both U.S. Highways until they cross into Tennessee.

From its point of origin in Houston County, State Route 1 is aligned very close to the Alabama-Georgia border, coming within less than one mile of the border at both Eufaula and Phenix City. At Phenix City, US-431 and unsigned State Route 1 begin a concurrency with U.S. Highway 280 and unsigned State Route 38 and turn to the northwest. At Opelika, US-431 and State Route 1 divert from US-280 and resume their northward orientation.

East of Oxford, State Route 1 and US-431 merge with westbound U.S. Highway 78 and unsigned State Route 4. At Oxford, State Route 1 and US-431 begin a gradual northwestward trajectory, passing through Anniston, Gadsden and Guntersville. The two routes resume their northward orientation upon merging with U.S. Highway 231 at Huntsville.
