Projects Under Construction


  • Concord Ave Sidewalk (posted 7/11/16) Crews have completed the paving.  Punchlist items, including driveway aprons, are still in the works.

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. Current plans are available for viewing at Samuel Hadley Public service building, 201 Bedford Street. Please contact Dave Cannon in Engineering for more information.


  • Street Resurfacing 2016 (updated 7/22/16)  Tree crews will be on Prospect Hill Rd on Thursday, July 28th working from 7am - 7pm removing trees in advance of sidewalk work.  The road will be closed. See detour map.

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.  Sealcoating Inc will also be in Town as they have the contract for the specialized resurfacing. Crews from Sealcoating have begun to put down the chip seal on Grove St.  The road will feel bumpy but please note this is only the first stage.  Other roads prepped and soon to be surfaced are: Burlington, North, Dewey, Gould, Grimes, Demar and Partridge.  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.
