Corridor X-1 or the Birmingham Northern Beltline is a proposed 50.08-mile (80.60 km) northern by-pass route around Birmingham, Alabama through northern and western Jefferson County that is projected to be completed by 2025. Along with the existing I-459, the Northern Beltline would complete the bypass loop of central Birmingham for all interstate traffic.

Current plans for the route have it connecting at I-459's current southern terminus in Bessemer with I-59 at approximately mile marker 147 to the northeast of Trussville near Argo. Additional studies are underway to determine the economic feasibility to continue the route from its proposed northern terminus to I-20 in the Leeds/Moody area.

The route has been designated as the Appalachian Regional Commission, High Priority Corridor X-1, State Route 959 and Interstate 422.


As early as the 1960s, the prospect of a complete beltway encircling Birmingham was envisioned. Although the proposal was initially dropped from the original Interstate Highway System, the completion of Birmingham's outer beltway has been speculated since the completion of I-459 in 1985. By 1989, the first federal and local funds were earmarked for a project to study the feasibility of constructing the route.

In September 1993 the Birmingham Metropolitan Planning Organization made a $500,000 request from the Alabama Department of Transportation for preliminary engineering of the beltline. Through the continued efforts of representative Spencer Bachus, in June 1995, the project was designated by the Federal Highway Administration as part of the National Highway System. As a result of this designation, the beltline would be eligible for federal transportation dollars.

In 2000, the Northern Beltline was added to the area’s Transportation Plan, and in 2001, Senator Richard Shelby and Congressman Spencer Bachus secured $60 million to buy right-of-way and do preliminary engineering for the route. In 2003, Shelby secured an additional $2 million for the continued purchasing of right-of-way. Progress continues with the purchasing of additional right-of way through the county as of 2006. Right of Way for the 1.34 mile segment near Pinson between Alabama 75 (exit 26) and Alabama 79 (exit 25) has been completed and construction commenced at 7 AM central standard time on Monday February 24, 2014.[2]

In May 2009, Bachus announced in the Birmingham News that the Northern Beltline had been designated as Interstate 422.[3]

Construction started February 24, 2014 which will connect Alabama State Route 75 and Alabama State Route 79.[4]
