Status
General construction activities are underway at the Westford 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.
Typical work hours are weekdays from 7 AM to 3 PM and require occasional lane closures.
Weather and unexpected circumstances make all construction activities subject to change without notice, but we will do our best to keep you updated.
Gorham Street Bridge Demolition Work
Steel erection operations will continue beginning the evening of Sunday, June 21, 2026 and will require overnight lane closures on I-495 northbound and southbound below the Gorham Street Bridge. These lane closures will be in place nightly from 9 PM to 5 AM the following morning and will be completed on the morning of Friday, June 26, 2026.
Additionally, rolling roadblocks will be necessary which will briefly close an additional lane for the southbound traffic on I-495. The roadblocks will be implemented intermittently for a maximum duration of 20 minutes several times throughout each work night during the hours of 1AM to 4AM.
