'''U.S. Route 331''' is a spur of [[U.S. Route 31]].  It currently runs for 151 miles (243&nbsp;km) from [[Montgomery, Alabama]] at [[U.S. Route 80]] and [[U.S. Route 82]] to [[Santa Rosa Beach, Florida]] east of [[Fort Walton Beach, Florida|Fort Walton Beach]] at [[U.S. Route 98 in Florida|U.S. Route 98]]. Unlike [[U.S. Route 131]], [[U.S. Route 231]], and [[U.S. Route 431]], U.S. 331 never intersects with its "parent" route, [[U.S. Route 31]]; the two routes come within {{convert|4|mi}} of each other in [[Montgomery, Alabama|Montgomery]].

==Route description==

===Florida===
{{main|U.S. Route 331 in Florida}}
[[File:Clyde B. Wells Bridge, U.S. Route 331.JPG|thumb|290px|The Clyde B. Wells Bridge of U.S. Route 331 spans the eastern section of the [[Choctawhatchee Bay]] in Florida near its intersection with [[U.S. Route 98 in Florida|U.S. Route 98]].]]
U.S. 331 begins at an intersection with [[U.S. Route 98 in Florida|U.S. Route 98]] in [[Santa Rosa Beach, Florida|Santa Rosa Beach]] in [[Walton County, Florida|Walton County]]. It then crosses the [[Choctawhatchee Bay]] on the [[Clyde B. Wells Bridge]], a {{convert|2.27|mi}} long span, and enters the eastern side of [[Freeport, Florida|Freeport]]. As it continues north, a [[spur route]] of U.S. 331 branches off and goes southwest back into town. The main route continues north for several miles before intersecting [[Interstate 10 in Florida|Interstate 10]] and forming a concurrency with [[U.S. Route 90 in Florida|US 90]] in [[DeFuniak Springs, Florida|DeFuniak Springs]]. The concurrency runs westward briefly until U.S. 331 branches off and continues to the northwest. It moves through a few small communities before passing through the town of [[Paxton, Florida|Paxton]] and crossing into [[Covington County, Alabama]].

===Alabama===
Once crossing the state line, U.S. 331 immediately enters [[Florala, Alabama|Florala]], where it starts a concurrency with [[Alabama State Route 54]] on the east side of town. The highway continues into downtown Florala, where [[Alabama State Route 55]] joins the concurrency (this intersection serves as a terminus for AL-54).

U.S. 331 continues northward to [[Opp, Alabama|Opp]], where it becomes concurrent with [[U.S. Route 84 in Alabama|U.S. 84]] as a bypass around the eastern side of town. A business route of U.S. 331 continues northward through town and rejoins U.S. 331 north of Opp, just after U.S. 84 leaves the concurrency with U.S. 331. The highway then continues northward and enters [[Crenshaw County, Alabama|Crenshaw County]]. It keeps north and into the town of [[Brantley, Alabama|Brantley]], where [[U.S. Route 29 in Alabama|U.S. 29]] forms a concurrency with U.S. 331.

The highways continue north into [[Luverne, Alabama|Luverne]], where U.S. 29 turns northeast and U.S. 331 turns northwest as they leave town. U.S. 331 soon turns back to the north and passes through several small communities before entering [[Montgomery County, Alabama|Montgomery County]]. It passes through several more small communities before entering the southern part of the city of [[Montgomery, Alabama|Montgomery]]. It then intersects the southern bypass of the city ([[U.S. Route 80 in Alabama|U.S. 80]] and [[U.S. Route 82 in Alabama|U.S. 82]]). This intersection serves as the northern terminus for U.S. 331.
