    The plans include installation of a sidewalk along Concord Avenue from Waltham Street to Spring Street. This project involves construction of a 5 foot wide sidewalk, granite curb, field stone retaining walls and drainage improvements. The culvert carrying Hardy’s Pond Brook will be replaced and the traffic signal at Waltham Street and Concord ave will be upgraded.

  • Street Resurfacing 2016 (updated 5/18/16)  Crews from D&R are still working on Solomon Pierce as well as Turning Mill and Reed Street. Solomon Pierce will be closed to through traffic through to Friday, May 20th. Hours of closure are approximately 7 AM to 7 PM.  See map. Abutters will have access.  Please speak with the detail officer at the point of closure.  Turning Mill and Reed St is open but traffic will be impacted due to reclaiming operations.  

This year's resurfacing program utilizes a few different methods to resurface.  Crews from D&R will be milling and paving, as well as reclaiming roads to be repaved.  The town also has a contract out to bid for specialized resurfacing. These surface techniques will prolong the life of the current pavement. Follow this link to learn about the different surfacing techniques!

Please see map for the streets to be resurfaced this year.  Please note the legend which indicates the treatment pertaining to each road in this year's program.  On-street parking will be prohibited during construction.  You will be given as much access as the work allows and the DPW will do their best to minimize any inconvenience. Please note that work schedules are often altered by unforeseen events such as scheduling conflicts with other utility work which may result in delaying the microsurfacing to a subsequent year.  We will do our best to keep you informed. Our current schedule is here.
