U.S. Route 31
U.S. Route 31 or U.S. Highway 31 (US 31) is a major north–south U.S. highway connecting southern Alabama to northern Michigan. Its southern terminus is at an intersection with US 90/US 98 in Spanish Fort, Alabama. Its northern terminus is at an interchange with Interstate 75 (I-75) south of Mackinaw City, Michigan.
US 31 once crossed the Straits of Mackinac by car ferry to intersect US 2 north of St. Ignace, Michigan, in the Upper Peninsula and then formerly reached Mackinaw City along the southern approaches of the Mackinac Bridge (which has been taken over by I-75). It also formerly entered downtown Mobile, Alabama, via a long bridge over Mobile Bay.
The southern segment of US 31 connects the cities of Mobile, Montgomery, Birmingham, and Decatur in Alabama, and Nashville in Tennessee. The northern segment of US 31 connects Louisville in Kentucky, and Indianapolis in Indiana. From Nashville to Louisville, US 31 is signed U.S. Route 31W and U.S. Route 31E. From the Mobile Bay area in Alabama to Indianapolis, US 31 travels parallel to Interstate 65 (I-65).
US 31 begins in Spanish Fort, Alabama at a junction with US 90 and 98. Formerly, the route originated in Mobile, co-routed with US 90 and 98. Whereas Interstate 65 leaves the Mobile Metropolitan Area via a route on the west side of the city, US 31 leaves the Mobile area via a route on the eastern side of the metro area, passing through Bay Minette. I-65 has effectively replaced US 31 as the preferred route for through traffic, making US 31 a local connecting route.
Near Atmore, the route passes extremely close to the Florida Panhandle's extreme northwestern corner, missing by approximately 1000 feet.
At Flomaton, US 31 begins a 15-mile virtual east–west concurrency with US 29 that continues to Brewton. North of Brewton, US 31 assumes a northeast–southwest trajectory, passing through rural areas and small towns in Escambia and Conecuh Counties. In Evergreen, US 31 north and US 84 share a brief concurrency heading north and east out of town.
Although US 31 parallels Interstate 65 throughout Alabama, the two routes do not directly junction each other until they reach Pintlala in southern Montgomery County, which is 164 miles north of Mobile. The two routes do not junction each other again for another 22 miles. US 31 is routed along a bypass of Montgomery, the state capital. At Prattville, this route intersects U.S. Route 82.
North of Prattville, US 31 passes through rural areas of Autauga and Chilton Counties, primarily along two-lane roadways. Between Prattville and Alabaster, US 31 has three interchanges with I-65.
