During the Sumner Tunnel shutdown, alternatives include free trips on the MBTA Blue Line, free and reduced-cost ferry trips, free and reduced parking at MBTA and commuter rail lots, and discounted tolls for residents using the Tobin Bridge and Ted Williams Tunnel1. Commuters are advised to consider these options and plan for extra travel time.
The budget for the Sumner Tunnel rehabilitation project is $160 million. The project aims to restore the nearly 100-year-old tunnel, including structural repairs, replacement of the driving surface, and upgrading various systems to improve safety and climate resilience.
