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 8/24/16)  

Surfacing crews will be on Lincoln Street from Marrett Road to the Town line on Friday, 8/26.  The road will be partially closed with alternating one way traffic being directed by detail officers. See map.  The surface does cure pretty quickly, and crews will try to get abutters in and out, but if you have a need to get out during the day, please talk to the inspector ahead of time if possible, to coordinate your access.  Work hours are from 7am to 7pm.  Paving crews from D&R will be paving Follen Road on Wednesday, August 24th and Thursday, August 25th from 7am-7pm.  The road will be partially closed with through traffic from Pleasant St heading towards Marrett having access.  Traffic coming from Marrett will be directed to Mass Ave as a detour. (see map) Crews will move onto Coolidge Ave for Friday and that road will be completely closed during paving operations which is expected to be from 7am-5pm.(see map) Cars must be parked off the street during paving/surfacing work. Weather and other factors can impact this schedule.  Please seek alternate routes if possible and plan accordingly.  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. 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. 


  • Water Distribution Improvements Contract 16-52 (updated 8/8/16)  Water main work on Mass Ave from Winthrop Rd to Hunt Rd will begin on August 18th.  Work hours are 7:30 am-4pm and this is anticipated to take about 5 work days. (no weekends) No Road closure is anticipated, but as this is a busy intersection, traffic will be impacted on Woburn St, Winthrop Rd, and Mass Ave.  Please seek alternate routes and plan accordingly. See map.

All the new water main between Marrett Road and Pleasant Street is complete. Crews are now working on the connection of services for homes to the new main. This entails digging a trench across the complete width of the street at every building between Marrett Road and Pleasant Street. To complete this work, the road will have to be narrowed to one lane with traffic alternating in each direction. (Complete closure will not be necessary.) The work will be done at night, from 8 pm to 5 am. This restriction will begin Monday, June 13th and continue for approximately 6-8 weeks.  If you are interested in being on an email distribution list set up for this project, please email the request to Please be aware while anyone may request updates, they are geared towards direct abutters.

Water crews will be working on a water main on Eldred St the first week of August.  No road closure is anticipated.
