Huntsville Northern Bypass Phases II & III
Published on
SUMMARY
This project extends the Northern bypass from U.S. 231 (North Memorial Parkway) to U.S. 72 East. It is scheduled to be completed in two phases: from U.S. 231 to Winchester Road, and from Winchester Road to U.S. 72.
The Northern Bypass is designed to be part of the City’s future “loop” road, improving and connecting roadways from Research Park Boulevard to Martin Luther King Boulevard, Bob Wade Lane, North Memorial Parkway, Winchester Road, 72 East, 431 South, Cecil Ashburn Drive, and South Memorial Parkway.
STATUS
The City of Huntsville is currently working on this project to extend the Northern Bypass east of Memorial Parkway to U.S. 72, consisting of approximately 12 miles of new 4-lane divided, limited access highway as part of State Route 255 extension between U.S. 72 East to Memorial Parkway, Interstate 565 and directly to Redstone Arsenal Gate 9. This project is multijurisdictional and is funded through the Huntsville Area Metropolitan Planning Organization (MPO) in partnership with Madison County and Alabama Department of Transportation using federal, state and local funds.
The project is anticipated to take many years; it is currently in the corridor study phase to determine a feasible alignment with minimal conflicts. An environmental document is being updated in accordance with Federal Highway Administration (FHWA) regulations while identifying a new corridor resulting in multiple conflicts with existing developments from a previous corridor study. Design is anticipated to start in 2027 or upon approval from FHWA. Acquisition is anticipated to begin near 2029. The project may be constructed in phases with the first phase tying to Winchester Road initially depending on the scope, timeframe, and funding as the design progresses.
