The Massachusetts Department of Transportation (MassDOT) has a comprehensive mitigation plan to address travel impacts and provide cost effective alternative transportation options for residents and visitors during of the scheduled closure of the Sumner Tunnel. The tunnel will be fully closed for one month between July 5 an August 5, 2024, to facilitate work on the Sumner Tunnel Restoration Project. The tunnel will be closed on select weekends between May and June of 2024, and between August and November of 2024. View the full schedule here.

Travelers are encouraged to Ditch the Drive and use alternative means of travel. MassDOT has created a menu of safe, efficient commute options while the tunnel is closed for repairs. Travelers can utilize MassDOT 511 to help review traffic conditions and MBTA’s Trip Planner to plan their public transit trips. Additional details on travel options are below.

Logan Airport travel tips

To reduce traffic congestion during tunnel closures, MassDOT encourages those traveling to or from Logan Airport to leave their cars at home and explore Massport’s list of transportation options to and from Logan, which include: the Blue Line or Silver Line, the Logan Express, the Logan Water Taxi, or the Hingham/Hull Ferry.

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 the Ted Williams Tunnel and re-direct traffic to minimize the backup on the mainline of I-90. Additionally, vehicles traveling on Route 1A/I-90 westbound towards Ted Williams Tunnel may see one less through lane on I-90 westbound. During some peak traffic periods, 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 closures of the Sumner Tunnel and provide safer driving conditions inside the Ted Williams Tunnel.
