Traveling to and from Logan Airport

Typical driving routes to the airport will remain available for use including the Ted Williams (I-90), for travel in both directions, and the Callahan Tunnel (Rt 1A North), which carries traffic to Logan Airport/East Boston from downtown Boston.

If you’re driving from Logan Airport and headed to I-93 North or the North End neighborhood of Boston, a number of signed detours will be in effect during the closure of Sumner Tunnel (Rt 1A South). Follow the links below to view the detour routes and plan your trip.

Travel tips to the North End and Downtown Boston

Signed detour maps for travel to the North End and Downtown Boston can be found here:

East Boston to Downtown Boston

Revere to Downtown Boston

In certain situations, the buildup of traffic exiting Logan Airport can extend out into East Boston. In an effort to minimize traffic backups throughout Logan Airport and on neighborhood streets, MassDOT can make real-time changes to travel lanes in the Ted Williams Tunnel.  While these changes do not entirely eliminate congestion, they are implemented in an effort to balance traffic volumes during weekend closures of the Sumner and provide safer driving conditions inside the Ted Williams Tunnel.

Anticipated Activities

July 5 – August 31

During this 8-week closure, MassDOT will be removing the existing suspended tunnel ceiling, installing precast ceiling panels, updating light fixtures, installing new camera systems, and repairing roadway slabs. Work will be taking place continuously, 24/7, throughout the 8-week closure.

Local and Regional Impacts

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