Interstate 22 (abbreviated I-22), when completed, will follow the U.S. Highway 78 corridor along a 176 mile (283 km) route from Memphis, Tennessee to Birmingham, Alabama. The limited access freeway will connect Interstate 55 and Interstate 40 in the northwest to Interstate 65 and Interstate 20 in the southeast, passing through the cities of Tupelo, Mississippi; and Jasper, Alabama.

The part of I-22 east of Fulton, Mississippi was approved in 1978 as Corridor X, part of the Appalachian Development Highway System. Parts of the highway have been under construction ever since, with the final portions in Northwest Alabama remaining to be completed. Funding for those sections has been a priority for U.S. Sen. Richard C. Shelby (R-Ala.), who serves as Chairman of the Senate Transportation Subcommittee. In 2004 Corridor X was designated as Future Interstate 22 by Public Law No: 108-199, and the designation was made official on April 18, 2005. In Alabama, green signs reading "FUTURE/I-22/CORRIDOR" at left and an I-22 shield with "FUTURE" instead of "INTERSTATE" at right were unveiled April 18, 2005.[1] A 94 mile (151 km) stretch from Graysville, Alabama to the Mississippi state line is scheduled to open in December 2006. Current plans call for Interstate-22 to be completed in 2012.
