 The project's budget is $5.445 billion; upon completion, the Northern Beltline will be the most expensive road in Alabama's history, and among the most expensive per-mile ever built in the United States.Current plans for the route have it connecting to I-59 at I-459's current southern terminus in Bessemer, 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 northeastern terminus southward to I-20 in the Leeds/Moody area in western St. Clair county.
