U.S. Route 43
U.S. Route 43 is a 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.
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 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 along its entire length in the state. It also has an unsigned concurrency with SR 227 between Saint Joseph and Loretto.
