Travel Tips throughout the Sumner Rehabilitation project
East Boston Ferry from Lewis Wharf to Long Wharf Returns
The East Boston ferry will be in operation throughout the first full closure of the tunnel and will be fare free for all riders.
Preparing for the first full 8-week closure (7/5/23 – 8/31/23)
MassDOT encourages users of the Sumner Tunnel/Route 1A South to prepare for the first of two 8-week shutdowns of the tunnel. Expect extra travel time, adjust your commute time, work from home if you can, and/or consider alternatives to driving. These alternatives include Blue Line, Commuter Rail, Silver Line, Ferry, and Bus. Learn more about your options by visiting the MBTA trip planner.
Traveling to and From Logan Airport
Vehicles leaving Logan Airport should be aware of ongoing traffic impacts during the Sumner Tunnel closures. Periodically, Massport will close the ramp connecting the airport to Ted Williams Tunnel and direct traffic to the Sumner Tunnel to minimize the backup on the mainline of I-90. Additionally, vehicles traveling on Route 1A/I-90 westbound towards Ted Williams Tunnel should expect one less through lane on I-90 westbound. On Saturdays and Sundays between 10 a.m. and 9 p.m. one lane is converted to a merge lane to help vehicles leaving Logan Airport to freely join the I-90 mainline. While these changes do not eliminate congestion, they are implemented in an effort to balance traffic volumes during weekend closures of the Sumner Tunnel and provide safer driving conditions inside the Ted Williams Tunnel.
As part of Phase 1 of the restoration project, the Sumner Tunnel will be closed each weekend through Summer 2023. The tunnel will close on Fridays at 11:00 p.m. and reopen on Mondays at 5:00 a.m. Work will be taking place continuously throughout the weekend.
Listed below are the anticipated construction activities for the next several work weekends.
Mitigation plans for dust, noise, vibration, pest control, and traffic will be in effect during construction.
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.
