Commonwealth Avenue Improvements (Church St. to Laws Brook Rd.)

Town Contact:

Justin Richardson, Assistant Town Engineer, 978-318-3213,

CPW'S General Contractor:

  1. Newport Construction Corporation
    Contact:  TBD

Other Contractors for Utility Projects:

  1. Concord Municipal Light Plant (CMLP)
    Contact:  CMLP Engineering
  2. National Grid
    Contact:  TBD

Construction Schedule:

  1. CMLP has replaced 4 light poles bases and light poles (7/1/2022).  It is anticipated that CMLP’s construction will be completed around the end of July 2022.
  2. National Grid has not provided the Town with a construction schedule, but CPW is aware that National Grid is experiencing delays. The construction schedule will be provided here as soon as it becomes available. 
  3. CPW’s portion of the project road and sidewalk reconstruction can only commence after CMLP and National Grid have completed their construction.  Currently, it is anticipated that CPW’s General Contractor will commence work at the end of July.  This schedule will be further updated when CPW has a more realistic understanding of the timing of CMLP’s and National Grid’s completion. The road and sidewalk reconstruction is expected to run through the end of October 2022.
  4. National Grid’s work will occur Monday thru Friday except for holidays, 9:00 AM to 3:00 PM. CMLP and Newport Constructions work schedule may be slightly different, but it will be provided here when it becomes available. Notice will be given for any exceptions for work outside of these days and hours to address critical construction needs. 

Pedestrian, Traffic and Access Management:

CPW Engineering continues to work with CMLP and National Grid to minimize disturbance to the traffic during their utility project construction.  However, this construction is anticipated to impact some parking spaces and at least one lane of the roadway during certain portions of the construction. CMLP's impact to the area will be less and they will have CPD present to mitigate pedestrian and vehicular traffic. The Town is expecting a final traffic management plan from National Grid prior to their start of construction. The Traffic Management Plan for this portion of the project will be added here when it becomes available.

During CPW’s Complete Streets Project and road reconstruction, the roadway and street parking will be impacted by the repaving of the roadway and the curbing installation.   Additionally, portions of sidewalk will be temporarily closed because a large portion of the project is the re-construction of the sidewalks. Pedestrian access to all businesses and residences will be maintained throughout construction. The Traffic Management Plan for this portion of the project will be added here when it becomes available.

Project Overview:

1.  Complete Streets Project:

Background information for the Town of Concord Complete Streets Program can be found on the Town’s Website in the link below. 

MassDOT’s Complete Streets Tier 3 Construction Award Contract was executed with the Town in 2020. Commonwealth Avenue was one of three projects that the Town received funding for through this program. Below is an existing conditions image of the project area:

Project Description:

The major items on the Commonwealth Avenue Complete Streets Project includes rebuilding the existing non ADA (Americans with Disabilities Act) compliant sidewalks and curbs on both sides of the street from the Railroad crossing to Beharrell Street and Bradford Street, construct two curb bump outs at each crosswalk to improve pedestrian safety and calm traffic, construct a new crosswalk at the intersection of Church Street and Commonwealth Avenue for additional pedestrian access, and implement new pavement markings to provide traffic calming, pedestrian and bicycle safety. This design was performed by The Engineering Corp. (TEC, Inc). See design plan below.

Engineering staff presented the preliminary design to the West Concord Advisory Committee and the Commission on Disability and incorporated their feedback into the final design. The construction of the project was put out for bids in the spring of 2022. Engineering staff also presented the project to the Concord Business Partnership so make them aware of the proposed construction. 




B. Road Reconstruction Project:

This project includes full depth reconstruction of the Commonwealth Ave roadway from the railway tracks to the intersection with Laws Brook Rd to address the poor condition of the pavement surface. The pavement will be reclaimed and regraded to improve surface drainage and rideability. A layer of binder pavement will be installed prior to the start of curb work.  The top layer of pavement will be added towards the end of the overall project and this will be followed by pavement markings.  When CPW is programing road and sidewalk projects, Engineering staff reaches out to utility providers and any known proposed abutting private development to notify them of the future construction and that the roadway would go into CPW’s 5-year Moratorium Street list. Projects listed below resulted from this coordination.  This road project along with other roads in the 2022 Roads Program have been presented to the Public Works Commission and the public via public meetings held during FY2022. 

 The paving limits are shown below:

C. Street Light Replacement Project:

CMLP will be replacing the existing light pole bases and poles along Commonwealth Avenue. The locations of the light poles will be in the same locations as the currently exist.  The design of the proposed light poles is shown below:  

D. National Grid’s Gas Upgrades:

National Grid through a Grant of Location Request to the Select Board will transfer all services mains from their existing 4 inch main to the existing 8 inch main and abandon the 850 feet of the existing 4 inch main in place. The transfer of services main include the following:

  • tie in 4 inch Coated Steel gas main to 8 inch Coated Steel in the intersection of Laws Brook Rd and Commonwealth Ave with approximately 20 feet' of 4-inch Plastic, 
  • tie in 4 inch Coated Steel gas main to 8-inch Coated Steel at 74 Commonwealth Ave with approximately 5 feet of 4- inch Plastic.
  • tie in 2 inch Coated Steel gas main to 8 inch Coated Steel in the intersection of Commonwealth Av and Bradford St with approximately 30 feet of 2- inch.
  • tie in 2 inch Coated Steel gas main to 8 inch Coated Steel in the intersection of Commonwealth Ave and Beharrell St with approximately 60 feet of 2- inch. 

See National Grid’s Plan below:

Private development work will be provided here when it becomes available.
