U.S. Route 78 (US 78) is a major east–west U.S. Highway across the central part of Alabama. It is internally designated State Route 4 (SR 4) by the Alabama Department of Transportation (ALDOT), though the only section of SR 4 that is signed is along portions mainly west of Jasper. The section from the Mississippi state line to near Graysville is concurrent with Interstate 22 (I-22); from Graysville south to Birmingham, US 78 takes its original routing. East of Birmingham to the Georgia state line, US 78 has been replaced as a major through-route by I-20. The two routes roughly parallel each other, with junctions at Leeds and Pell City.^[1]

West of Jasper, old US 78 is signed as SR 118 to Guin, and the segment from Guin northward to I-22 at Hamilton is signed as US 43/US 278.

History

The routing of US 78 in the Birmingham area has changed several times over the years. Before the construction of a 4 lane routing in the 1950s, U.S. 78 east followed a two lane route through the heart of Graysville (Main Street) and then shared the current 4 lane until Adamsville when it became Main Street once again and then became Forestdale Boulevard near the present interchange of U.S. 78 and Minor Parkway. The original route crossed U.S. 78 and became Pratt Highway, which goes into the old steel mill community of Pratt City and then into Birmingham. In Birmingham, the routing passed near Birmingham-Southern College, turning east along 8th Avenue West, passing on the north side of historic Legion Field. The routing through downtown has moved slightly.
