Chelmsford – The Massachusetts Department of Transportation (MassDOT) will be hosting a public meeting on Wednesday, March 26, 2025, at 6:00 PM in the Chelmsford Police Station Training Room, 2 Olde North Road Chelmsford, MA 01824, to discuss the Chelmsford-Lowell Bridge Bundle Project and solicit questions. You can read more about this public meeting on the event page and download a meeting flyer in multiple languages.

MassDOT will fully replace two bridges in the Town of Chelmsford. These include Westford Street over I-495 in Chelmsford and Route 3A (Gorham Street) over I-495 on the Chelmsford/Lowell line.

The new bridges will improve the overall clearance and geometry of the bridge crossings. Roadway reconstruction work will improve vehicle safety and provide improvements for pedestrian and bicycle travel.

Each bridge will be replaced in two phases. Phase I is anticipated to begin in late June 2025. During Phase I, each bridge will be closed to vehicular traffic for 12 – 18 months. Pedestrian access will be maintained across each bridge during these closures, and bicyclist access will be maintained for Westford Street during the closure. A local detour route will be implemented at each bridge for all vehicles. When Phase I is completed, the bridges will reopen to all traffic.

Early action work is anticipated to begin in April 2025, with Phase I construction to commence on both bridges simultaneously beginning in June 2025.
