Location: Birmingham, AL
Client: Alabama Department of Transportation (ALDOT)

The Alabama Department of Transportation (ALDOT) selected Volkert to design the development of the Future I-22, known as “Corridor X.”

The Birmingham-area segments of Future I-22 will bring the interstate corridor between Memphis and Birmingham closer to fruition. Once Corridor X is tied into I-65, the roadway will be known as Interstate 22 and facilitate freeway passage from Atlanta to Oklahoma City. Together, the Corridor X projects represent one the largest roadway construction projects undertaken by ALDOT.

The project presented challenges of geometric complexity, environmental sensitivity, maintenance of traffic, and utility relocation. Services included roadway and bridge improvements, diamond and cloverleaf interchanges, and ties to existing side roads. Volkert performed the preliminary and final design plans.

The final design included a new, four-level tie-in interchange at I-65 and a new, at-grade intersection where Corridor X meets U.S. 31. The work for the 5.5-mile section along I-65 from 16th Street north to Five Mile Creek consisted of 3 miles of widening to the outside (from two lanes to six lanes), modifying four interchanges, and relocating 2.5 miles of I-65. Volkert also performed the right-of-way mapping for the entire project, including 260 tract maps and legal descriptions.
