Corridor X-1 or the Birmingham Northern Beltline is the proposed 50.8-mile (81.8 km) by-pass route around Birmingham, Alabama through northern and western Jefferson County 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.
