Navigating the Sumner Tunnel Closure: Traffic Impacts and Travel Alternatives

The Sumner Tunnel in Boston will be fully closed from July 5 to August 31, 2023, with additional closures planned in the future. The closure will heavily impact East Boston, South Boston, and waterfront neighborhoods, causing congestion in the Ted Williams Tunnel and on the Tobin Bridge. Travelers are advised to avoid driving to Logan Airport and instead utilize alternative transportation options such as the Blue Line, discounted tolls, and the East Boston ferry, which will be free during the closure. Detours will be in place, and taxi and rideshare availability may be limited.
