Project Update – Week of 9/8/25
Sewer extension work on Powder Mill Road has progressed from the Powder Mills Apartment Project Site to the intersection of Powder Mill Road and Sudbury Road.
The Work Zone has shifted to complete work on High Street and into the intersection with Powder Mill Road over the next few weeks. Access to the Powder Mill Plaza may be temporarily restricted to the Knox Trail side entrance during the latter portion of this week and into early next week during Construction Hours. In this event, directional signage will be in place informing motorists of this condition, directing them to Knox Trail from Powder Mill Road and High Street. Within High Street, vehicular traffic will be restricted to the southbound travel lane as necessary and directed using a combination of cones, flaggers, and Acton Police Officer details.
The expected duration of the project is from early June 2025 to late November 2025. Please refer to the phased work plan below for the project schedule details.
As construction progresses, we will provide an updated plan.
For the purposes of worker safety and project efficiency during Construction Hours, we intend to use one-lane closures on the affected roadways, leaving the westbound lane on Powder Mill Road and the southbound lane on High Street open during these hours, when work occurs in these areas. The closed lanes will be reopened after work is complete for the day, and on days when work will not occur (i.e., weekends and certain holidays).
There may be an occasional need to temporarily close both travel lanes. In this event, a detour route will be set up during these temporary closures, with traffic detail police officers assisting motorists and directing the flow of traffic. The route will also be posted to this page.
Thank you for your patience and cooperation!
