  • Street Resurfacing 2016 (updated 11/9/16)  Crews will be painting and taking care of other punchlist items on the Minuteman Bikepath tomorrow, November 10th, from 7am-7pm.  the bikepath will be open, but there will be trucks and other equipment in the right of way so please use caution.

D&R crews are installing sidewalk on Prospect Hill.  Unfortunately, the work will require a closure from 9am-3pm Monday-Friday through to the end of the month.  See detour map

You will notice crews in various spots in town taking care of the punchlist items including driveway aprons on the roads that got paved this year. 

This year's resurfacing program utilized a few different methods to resurface.  Crews from D&R resurfaced roads in the traditional methods: milling and paving, as well as reclaiming roads to be repaved.   Sealcoating Inc had the contract for the 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 Paving Map 2016 traditional methods map for the streets to be resurfaced and Paving Map 2016 Surface Treatments map for streets that will be microsurfaced with the special techniques described above.  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. Please contact with any questions or concerns regarding the paving.
