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 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.

Detour options

Beginning the weekend of June 10, 2022, the Sumner Tunnel will close every weekend, from 11 P.M. on Friday to 5 A.M. on Monday.

In coordination with local agencies and emergency services, the following detours were determined as the most efficient options to divert traffic away from the Sumner Tunnel while it is closed. When possible, it is highly encouraged to utilize public transit options.

Drivers from East Boston seeking to reach the Downtown Boston area will be rerouted to I-90/Ted Williams Tunnel via Bennington Street and onto I-93.
