BOSTON — The Sumner Tunnel reopened to traffic today at 5 a.m. before the morning commute. The tunnel had been completely shut down since July 5 as part of a multi-year restoration project. The closure was the next phase of a project that began in April of 2022 and included work on the tunnel roadway, walls, drainage and additional improvements which will increase safety and climate resiliency. The project is a $160 million investment in the Commonwealth’s infrastructure.
During the 31-day shutdown, the existing asphalt was removed from the length of the roadway and the concrete below was rehabilitated. Granite curbing and drain inlet were replaced and the installation of new fireboard was completed. The entire length of the roadway was repaved. The new pavement will be lined, and the tunnel cleaned prior to reopening.
The Sumner Tunnel Restoration Project offered a variety of mitigation options for individuals coming from all travel points. Mitigation options included free trips on the MBTA Blue Line; free and reduced cost water ferry options; reduced Commuter Rail fares for riders; reduced parking costs at MBTA and Commuter Rail parking lots and garages; discounted tolls for residents; and additional options for travelers to and from Logan Airport.
A limited number of weekend closures are planned for the fall. At their conclusion, no later than the end of November, the project will be complete.
