undivided highway. Alabama Once crossing the state line, US 331 immediately enters Florala, where it starts a concurrency with Alabama State Route 54 (SR 54) on the east side of town. The highway continues into downtown Florala, where SR 55 joins the concurrency (this intersection serves as a terminus for SR 54). US 331 continues northward to Opp, where it becomes concurrent with US 84 as a bypass around the eastern side of town. A business route of US 331 continues northward through town and rejoins US 331 north of Opp, just after US 84 leaves the concurrency with US 331. The highway then continues northward and enters Crenshaw County. It keeps north and into the town of Brantley, where US 29 forms a concurrency with US 331. The highways continue north into Luverne, where US 29 turns northeast and US 331 turns northwest as they leave town. US 331 soon turns back to the north and passes through several small communities before entering Montgomery County. It passes through several more small communities before entering the southern part of the city of Montgomery. It then intersects the southern bypass of the city (US 80 and US 82). This intersection serves as the northern terminus for US 331. History The original version of US 331 traveled along what is now U.S. Route 29 south of Flomaton, Alabama between 1926 and 1936. The current version was revived in 1953. Beginning in 1956, signs for U.S. Highways in Florida had different colors for each highway. The shield for US 331 was green with white lettering and outline, until the state was forced by the federal government to conform to standards that required consistent black-and-white signs in 1993. Until 2007, US 331/SR 83 turned left at State Road 20 in Florida in a short concurrency until it reached Madison Street, then traveled north past Owl's Head Road just south of Eglin Air Force Base.
