State Route 79 (SR 79) is a 117-mile-long (188 km) state highway that extends northeastward from Birmingham to the Tennessee state line. Prior to the completion of Interstate 65 (I-65), SR 79 was the southern part of the route that connected Birmingham and Huntsville.
The southern terminus of SR 79 is at an interchange of Tallapoosa Street with I-20/I-59 (exit 128) near Birmingham–Shuttlesworth International Airport. Prior to the completion of I-20/I-59, the terminus of SR 79 was at an intersection with US 31, US 78, and US 280 at the intersection of 8th Avenue North and 24th Street in downtown Birmingham.
Alabama State Route 79 begins at a modified-diamond-interchange in east Birmingham, near Birmingham Int'l Airport. The route turns northeast on a four-lane divided highway and continues in this direction until it reaches Pinson. It junctions with AL-151, which leads to AL-75. The route loses its four-lane divided highway status and becomes a two-lane road, crossing into Blount County.
In southern Blount County, there are no major junctions until it reaches Cleveland. It junctions with AL-160 and continues north for just about a mile, reaching U.S. 231. It continues on its right-of-way until it crosses the Locust Fork and leaves U.S. 231 in Blountsville. It junctions with U.S. 278 a few miles later. It eventually enters Marshall County.
It eventually reaches Guntersville. It junctions with U.S. 431. It maintains a concurrency with it, junctioning with AL-69 and AL-227 before splitting off from U.S. 431 and heading north to the Jackson County line.
In Jackson County, there are no major junctions until it turns off of its right-of-way—its right-of-way becoming AL-279—in Scottsboro. It junctions with U.S. 72 and AL-35 before leaving the city. In Skyline, the route junctions with AL-146. It continues north until it crosses the Tennessee state line.
