Future Interstate 22 & U.S. 78 - Corridor X

U.S. 78 between Memphis, Tennessee and Birmingham, Alabama represents Appalachian Regional Development Corridor X. The route comprises a full freeway from the Tennessee state line at Memphis to Coalburg Avenue in north Birmingham. The corridor doubles as Future Interstate 22, with full Interstate status expected when the interchange with Interstate 65 near Fultondale opens to traffic by October 15, 2014. Signs proclaiming the route a Future Interstate highway were approved for Corridor X in April 2005.4

Construction at the future interchange between Interstates 22 and 65

A tri-level stack interchange will facilitate the movements between Interstates 22 and 65 upon completion. A fourth level will see the I-22 mainline continue to U.S. 31 below I-65 and its c/d roadways. This view looks south at the future I-22 east to I-65 north flyover from the 47th Avenue overpass. Photo taken 10/21/12.

Planning for Corridor X started in 1978, with the first funding in place by 1983.3 26 miles of Future Interstate 22 opened to traffic on November 14, 2007. Included is the stretch between Industrial Parkway (Exit 65) in Jasper to U.S. 78 at Graysville (Exit 85) and the completion of Exit 85 to Cherry Avenue (Exit 91)1, which previously opened to local traffic in early June 2007.2 Another 20 miles of freeway, between SR 129 (Exit 30) and SR 118 west of Jasper, opened November 22, 2005.3 See Interstate 22 @ Interstate-Guide for construction information and a more detailed history.

The easternmost 2.5 miles of Future Interstate 22, between Cherry Avenue and Coalburg Road, opened to traffic on December 9, 2009. This leaves the 2.5-mile approach to Interstate 65, currently under construction as part of a $168.6-million contract to built a four-level stack interchange. Work began in August 2010 on the four year project.5

Scenes pertaining to Future Interstate 22 & U.S. 78
These special blue & white Appalachian Regional Corridor X shields are in use all along the 30-mile Mississippi to Winfield segment of Future Interstate 22. Alabama 4 is the unsigned state route counterpart for U.S. 78 across the state, but is signed well along this segment of freeway. Photo taken 09/25/03.

Whitehouse Road travels east from Industrial Parkway parallel to Future Interstate 22. This view looks from just north of the adjacent road at Corridor X during its construction.

A generous rock cut, alluding to the rocky nature of the Appalachian Piedmont, is evident along Future Interstate 22 between Whitehouse and Walker County Lake Roads, east of Exit 65. Photo taken 09/25/03.
