RE: MWRA Water Main Project – Lexington Street Detour
Dear Resident and Business Owner,
The MWRA and its contractor are expected to move the work site to north of Trapelo Road to continue efforts to construct the new water main pipelines and connections along Lexington Street. This will require traffic changes along the roadway to ensure an efficient and safe work zone for crews to advance the project, and to enable a consistent flow of traffic through and/or around the work site.
Please be advised Lexington Street southbound between Concord Avenue and the Waltham municipal line will only be open for local travel. There will be no southbound access past the Watertown Savings Bank Monday, March 10, 2025. Lexington Street will remain open to northbound traffic at all times. This work is expected to take approximately 8-10 weeks to complete.
A detour will be in place to direct southbound private vehicles west along Concord Avenue to Spring Street / Smith Street, then south along Smith Street to Trapelo Road, and then east onto Trapelo Road, where motorists will be able to turn south onto Lexington Street to continue their route (a second detour that traverses east of Concord Avenue will also be provided). However, commercial trucks, which are not allowed along Concord Avenue, will be detoured to Hayden Avenue then onto Spring Street, and then will follow along the detour route coordinated for all vehicles.
While work hours are expected to be Monday – Friday: 7:00AM to 3:00PM, the detour will be in place 24 hours per day due to the size and location of the trench needed to install the new pipeline.
· Please note that there may be days where the work will extend beyond 3:00PM due to unforeseen schedule shifts.
For any questions, please contact the following MWRA Representatives:
- Matt Messier – (617) 733-2961 or Matthewm@engineeredconceptsinc.com
