Status
Early action activities are underway near and on the Westford and Gorham Street bridges. This work includes utility relocation work at both the Westford Street and Gorham Street Bridges. A temporary traffic signal has been installed at the intersection of Carlisle Street, Boston Road and Manning Road to facilitate the Gorham Street detour.
Work hours for these activities is weekdays from 7 AM to 3 PM, and requires occasional lane closures. There will also be overnight work on I-495, which will require lane closures at each bridge location. Police details will be present to facilitate this work.
Weather and unexpected circumstances make all construction activities subject to change without notice, but we will do our best to keep you updated.
I-495 intermittent lane closures near Gorham Street continue August 26, 2025
MassDOT will be completing overnight substructure demolition work at the Gorham Street Bridge area requiring intermittent rolling roadblocks on I-495 northbound and southbound, beginning Monday, August 26.
This work is scheduled to take place during overnight hours, from 11 PM each night through 3AM the following morning, and will be in effect for approximately two weeks. These lane closures will be implemented intermittently for 10–15 minute periods several times throughout each work night. Demolition work may have intermittent noise impacts for nearby residents.
Gorham Street Bridge Phase I demolition work began July 2025
Phase 1 demolition work of the Gorham Street Bridge began on or about Monday, July 28 and is scheduled to last through mid-September. Typical work hours will be from 7PM nightly through 5AM the following morning. Lane closures underneath the Gorham Street Bridge on I-495 North and South will be in effect.
This demolition work will have noise impacts and may be disruptive. Noise monitoring stations have been installed and will be monitoring noise levels throughout this work. The project team will follow the approved noise and dust control plans to minimize impacts to neighbors.
Phase I construction began June 2025
Phase I bridge detours on the Gorham and Westford Street Bridges began following the conclusion of the 2024-2025 school year in late June 2025.
During Phase I, each bridge is closed to vehicular traffic for 12 – 18 months. Pedestrian access will be maintained across each bridge during these closures. During the Phase I closures, bicycle access will be maintained on the Westford Street Bridge and detoured on the Gorham Street Bridge. A local detour route is implemented at each bridge (see maps of detour routes). When Phase I is completed, the bridges will reopen to all traffic.
