U.S. Route 331 (US 331) is a spur of U.S. Route 31. It currently runs for from Santa Rosa Beach, Florida east of Fort Walton Beach at US 98 to Montgomery, Alabama at US 80 and US 82. Unlike US 131, US 231, and US 431, US 331 never intersects with its "parent" route, US 31; the two routes come within of each other in Montgomery. Route description Florida U.S. Route 331 begins at U.S. Route 98 in Santa Rosa Beach. From there it runs north towards a long concrete slab bridge over Choctawhatchee Bay. The bridge ends at Wheeler Point, and the road makes a sharp curve to the northeast where it encounters an intersection with County Road 3280 (CR 3280), and then turns straight north again. Running along the eastern edge of Mallet Bayou, and LaGrange Bayou, the road makes a less drastic northeastern curve at the bridge over Ramsey Branch, and it eventually intersects State Road 20 (SR 20) on the eastern edge of Freeport. From that point it runs along the eastern edge of Eglin Air Force Base, which includes the Eglin Wildlife Management Area. This territory ends across the street from the intersection of Edgewood Circle. After the intersection with Indian Creek Ranch Road, US 331/SR 83 makes a slight northwest curve to meet the southern end of County Road 278 (Coy Burgess Loop). The road runs straight north from there and becomes a divided highway as it approaches the north end of CR 278 just south of Interstate 10 (I-10) at exit 85 in DeFuniak Springs. Within the city, US 331/SR 83 remains a divided highway running in the same trajectory, where the only intersection of any level of importance is CR 280(Bob Sikes Road). After the intersection with Myrtle Avenue, it takes another slight curve to the northeast. Two more local intersections will be encountered before the road runs beneath a bridge for the CSX P&A Subdivision, and a parallel bridge with Baldwin Avenue just before the intersection with U.S. Route 90, where both U.S. Route 331 and SR 83 split into two separate concurrencies; US 331 turns left while SR 83 turns right. US 90/331 curves northwest where it encounters the western terminus of Baldwin Avenue, the very city street it crosses under on the north side of the P&A Subdivision. After this it runs along the same railroad line where it
