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 spring 2024 to summer 2024, the tunnel will be closed periodically.
Another full closure of the tunnel will occur summer 2024. This second 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.
