For example, south of Montgomery it is still named Mobile Highway, and northwardly it is referred to as the Birmingham Highway. Similarly, south of Birmingham it is referred to as Montgomery Highway, and northwardly it is referred to as the Decatur Highway. Throughout north Alabama plaques and signage refer to the route as the Beeline Highway. US 31 is co-routed with unsigned State Route 3 (SR 3) throughout the state until its junction with I-65 north of Athens.

Tennessee

The first mile in Tennessee, US 31 runs concurrently with I-65, somewhat parallel to which it runs until it splits in downtown Nashville, to become US 31W and US 31E, a relatively uncommon occurrence in U.S. Highways, though not unlike that which occurs to US 49 and US 45 in Mississippi, U.S. Route 19 in North Carolina and Tennessee, and US 11 in Tennessee. While upon crossing the state line from Alabama into Tennessee, US 31 (also State Route 7 R 7at this point) runs to the east of I-65, it crosses over I-65, changing names from Main Street to Elkton Pike on the overpass. According to this name change, US 31 runs through Elkton shortly after making this crossing. After passing through Elkton, US 31 wanders, away from I-65, towards the city of

. On its way to Pulaski, US 31 intersects with US 64 and does so once again in the center of the city. In Pulaski, US 31 serves as 1st Street in the downtown area. Just north of the downtown area of Pulaski, US 31 Alternate (US 31A) branches off US 31, serving first as East Grigsby Street, then as Lewisburg Highway, never to be visible from US 31 again until reaching downtown Nashville. Continuing north, US 31 meanders, following Richland Creek for a portion of the way, named Columbia Highway; naturally, as follows the typical naming trend for former connecting routes, halfway to

, the name changes to Pulaski Highway. US 31 runs by Lynnville in this process. As US 31 enters

, upon crossing James Campbell Boulevard (also SR 50), it is named Carmack Boulevard, at this point a decently wide road with two lanes on each side. While in Columbia, US 31 changes names two more times, once to South Garden Street (also temporarily sharing routes with US 412 and SR 99 in this area), and then to Nashville Highway while SR 7 departs from the street. It is a short stretch until US 31 hits an intersection with Bear Creek Pike. This is the northern terminus of US 43, and also the point at which US 412/SR 99 resumes its eastern trajectory, away from US 31. US 31 also picks up the path of SR 6 here, in addition to the historical significance of being the former warpath of the Confederate forces during 1863 and 1864, during the American Civil War. Upon leaving Columbia, US 31 develops a median and a speed limit not too dissimilar from that on I-65, which is still only a few miles to the east of the highway. On the way up to Spring Hill, US 31 passes straight through a small, corner town little-known to be called Neapolis. At this location, there is an on-ramp onto Saturn Pkwy (SR 396), named as such because it was once a highway connecting I-65 to the assembly plant belonging to Saturn Corporation, which no longer acts independently from its parent company,

. No more than two miles further up the highway, Saturn Pkwy has looped back around to begin its trajectory toward I-65, and there are more on and off ramps between SR 396 and US 31. At this point, US 31 returns to its original two-lane, narrow road format, and has entered the rapidly-growing city of Spring Hill, where it serves as Main Street, then as Columbia Pike in the adjacent Thompson's Station, a soon-to-be home of a golf course and luxury home development opened by Tiger Woods. North of Thompson's Station, US 31 intersects I-840, serving as exit 28 for the southern loop around Nashville. Further up the highway, US 31 shares an interchange with Goose Creek Pike, a direct route to I-65. US 31 continues up through historic Franklin, as Columbia Avenue. In the middle of Franklin, US 31 comes to a five-point intersection with the routes of US 431 and SR 96, and a

two blocks further north which continues the route of SR 96 to the east. US 31 then proceeds out of Franklin and to the northeast. As US 31 passes through Brentwood, the road widens, again to two lanes per side, and intersects with SR 254 at the point where it reaches less than a half of a mile from I-65 once again. At this point, US 31 remains within this distance from I-65 until reaching its split in downtown Nashville, traveling through the sites of the

now carries the route of US 31 between Holland, and St. Joseph, Michigan. All of US 31 between Indianapolis and Ludington, Michigan, is divided highway—some of it is freeway, including a bypass route of South Bend, Indiana. The segment between Indianapolis and South Bend is scheduled for upgrade or replacement with Interstate-standard freeway. Environmental impact studies have shown that the fifth phase of the then-to-be-constructed freeway segment between Napier Avenue near Benton Harbor, Michigan, and I-94 would be completed in mid-November of 2022; the segment officially opened on November 9th. The portion of I-75 north of US 31's northern terminus toward the Mackinac Bridge was designated part of US 31 prior to the 1990s and was US 31's northernmost portion to be built to freeway status. Since its truncation at the I-75 interchange, however, the northernmost segment of the US 31 freeway ends near Ludington. In Alabama, US 31 follows portions of the Pulaski Pike beginning at the Alabama–Tennessee State line at Ardmore, and was originally routed on what is now called

From Birmingham, it follows portions of the Columbiana Road and roughly parallels it in Hoover along the present widened route and intersects with the Ashville-Montevallo Road or the Cahaba Trail (SR-119) and follows it on a branch to Calera. US 31, beginning in Chilton County, follows a branch of the Talladega-Montgomery Stage Road, a road that went from Talladega and went south from Columbiana to near present-day Clanton, Verbena, and Montgomery, and was operated by Jemison, Ficklin, & Powell, who operated stagecoaches on the road. US 31 in Prattville came to the site of Reese's Ferry on the Alabama River, where it was replaced by the present bridge near Prattville. From Montgomery, US 31 follows parts of the Federal Road, and is presently routed on the Greenville Branch of the Federal Road, and follows the Montgomery-Mobile Road through Conecuh, and Escambia Counties and also intersects with the Pensacola Trading Path or the "Old Wolf Trail" from Burnt Corn.
