Sumner Tunnel Restoration: Traffic and construction updates

Sumner Tunnel restoration work will impact commuters, travelers, and people in the surrounding communities. Learn about the current traffic impacts and construction updates here.

Vehicles traveling from the airport should check Mass511 for real time traffic updates.

Weekly Traffic Updates

Tunnel Open

The tunnel is currently open. Additional closure dates will be posted once available.

Travel Tips throughout the Sumner Rehabilitation project

During weekend closures, MassDOT anticipates an uptick in regional traffic and encourages those traveling through the area to continue to Ditch the Drive and plan ahead. Effective on September 1, 2023, normal fares will resume throughout the MBTA system. Travelers can continue to utilize MassDOT 511 to help review traffic conditions and MBTA’s Trip Planner to plan their public transit trips.

 

Traveling to and From Logan Airport

During the closure of the Sumner Tunnel, MassDOT implements a relief lane for traffic exiting Logan Airport to the Ted Williams Tunnel (I-90) during times of lower traffic volumes on I-90 Westbound, typically beginning after about 11 a.m. and continuing into the evening hours. To implement this relief lane, MassDOT converts one travel lane on I-90 Westbound into a merge lane that allows vehicles exiting Logan Airport to freely join the I-90 mainline.

Construction Updates

From Fall 2023 to Summer 2024, the tunnel will be closed periodically.

Another 2-month closure of the tunnel will occur summer 2024. This second 2-month closure will be followed by weekend closures to complete the project by end of 2024.

Mitigation plans for dust, noise, vibration, pest control, and traffic will be in effect during construction.

Adjacent projects

In addition to the Sumner Tunnel restoration project, drivers should be aware that MassDOT continues to conduct additional necessary maintenance activities in the area, including the Ted Williams (I-90) and Tip O’Neill (I-93) tunnels. In most cases, maintenance activities require a reduction in travel lanes to allow for the safe completion of work. Understanding the potential travel impacts created by any reduction in travel lanes, this work is scheduled outside of peak travel hours to minimize the impact on regional travel.
