U.S. Route 43 (US 43) is a 410-mile-long (660 km) north–south United States Highway in the East South Central States of Alabama and Tennessee. It travels from Prichard, Alabama to Columbia, Tennessee. The highway's southern terminus is in Prichard, at an intersection with US 90. Its northern terminus is in Columbia, Tennessee, at an intersection with US 31/US 412/US 412 Bus.

Map of US-43, United States

In Alabama and Tennessee, all of the U.S. Highways in each state have one or more unsigned state highways designated along its length. US 43 travels concurrently with Alabama State Route 13 (SR 13) from its southern terminus to an intersection in southeastern Fayette County. For the rest of its length in the state, US 43 is concurrent with signed state highways. In Tennessee, US 43 travels concurrently with Tennessee State Route 6 (SR 6) along its entire length in the state. It also has an unsigned concurrency with SR 227 between Saint Joseph and Loretto.

Mobile County

US 43, along with unsigned SR 13 which is concurrent with it, begins at an interchange with US 90 (New Bay Bridge Road; unsigned SR 16) in the extreme southeastern corner of Prichard, in Mobile County.

US 43 enters Lawrence County and the city limits of Saint Joseph. The unsigned State Route 6 (SR 6) begins at the state line. In the main part of the city, US 43 begins an unsigned concurrency with SR 227 (Iron City Road). They curve to the northeast, leave Saint Joseph, and enter Loretto. There, SR 227 splits off to the southeast onto East Main Street. Then, US 43 intersects SR 98 (Rabbit Trail Road) in Leoma. It has an interchange with US 64 (unsigned SR 15; Lawrenceburg Highway) in Lawrenceburg. In downtown Lawrenceburg, US 43 intersects US 64 Bus. (Gaines Street). The highway briefly parallels the North Fork Buffalo River before beginning a curve to the north and crossing that river twice. Then, US 43 intersects SR 240 (Monument Road) and Spring Water Drive.

In Maury County, US 43 intersects SR 20. It intersects the southern terminus of SR 243 (South Main Street) in Mount Pleasant. It travels on an overpass over Mt. Joy Road and some railroad tracks. US 43 bypasses downtown by traveling through the western part of the city. It intersects SR 166 (1st Avenue). Then, it has an interchange with SR 243, which also leads to the Maury County Airport. It has an interchange with US 412 (unsigned SR 99) and the western terminus of US 412 Bus. (Hampshire Pike) in Columbia. At this interchange, US 43 and US 412 travel concurrently to the north-northeast. At an interchange with SR 50 (Williamsport Pike), the concurrency briefly re-enters the city before leaving again. The concurrency curves to the east-southeast and has an interchange with SR 7 (Santa Fe Pike). Then, they intersect US 31 and US 412 Bus (Nashville Highway). Here, US 43 ends, US 412 continues to the east-southeast on Bear Creek Pike, and SR 6 turns left onto US 31 north.

National Highway System

All of US 43, except for the approximately 18-mile-long (29 km) segment from the interchange with I-20/I-59 south of Knoxville to just northeast of its entering Tuscaloosa, is part of the National Highway System (NHS), a system of highways determined to be the most important for the nation's economy, mobility, and defense.

History

Prior to the completion of Corridor X in western Alabama, US 43 and US 278 shared a concurrency with US 78 between Guin and Hamilton. The highway used to extend up to Henderson, Kentucky. It was concurrent with I-24, I-65, the Pennyrile Parkway, and what is now present-day I-69. This part of US 43 was decommissioned when US 41 Alt. came into existence.

Future

Preliminary talks have indicated that Alabama state officials support a plan to upgrade US 43 to Interstate Highway standards from the Mobile metropolitan area to the I-20/I-59 interchange in Knoxville. However, no number has been specified. The plan is estimated to cost roughly $1.6 billion. The project is expected to help the economies of cities in the Black Belt by connecting communities in western Alabama, the Port of Mobile, I-65, and I-20/I-59.
