Here’s what to expect from upcoming Woburn to Wakefield Line Project construction.

This week excavation and duct bank installation will start on Salem Street at two locations. The first crew will work from Nablus Road towards Tobey Lane. The second crew will work near Patriot Circle, progressing towards Houston Street. While this work is ongoing, Salem Street (between Vernon Street and New Salem Street) will remain closed to through-traffic during work hours. As always, residential and emergency vehicle traffic will have access to the street with the help of police details on site.

At our work site on Main Street, we’re nearing completion of duct bank installation. Notwithstanding any unforeseen delays, we anticipate completing the majority of our work at this work site by the end of this week. Please note that until work is complete the traffic management plan at this work site will remain the limited two-way traffic facilitated by police details during work hours. 

As an additional reminder, excavation and duct bank installation on Montrose Avenue is ongoing. While work is ongoing on Montrose Avenue the street will remain closed to through-traffic during work hours. As always, residential and emergency vehicle traffic will have access to the street with the help of police details on site.

As part of our ongoing effort to complete our work as safely and as efficiently as possible, construction crews may extend their work at certain work sites through close of business on Saturdays. Moving forward, as information about Saturday work schedules becomes available, we will send follow-up updates. 

Lastly, please note that there will be no Woburn to Wakefield Line Project construction in Wakefield this Friday, July 3 or Saturday, July 4.

*Over the next week neighbors can expect to see:

  • Salem Street: excavation and duct bank installation.
  • Main Street: excavation and duct bank installation.
  • Montrose Avenue: excavation and duct bank installation.

Traffic Management Updates:

  • Salem Street: no through traffic, emergency, and residential vehicle access only.
  • Main Street: limited two-way traffic facilitated by police detail.
  • Montrose Avenue: no through-traffic, emergency, and residential vehicles access only.

As duct bank construction continues, please note that the Wakefield Police Department has the option to modify the traffic management plans based on their judgement and expertise, including street closures and traffic detours to ensure the safety of the general public. As always, police details will be present at our work sites to facilitate vehicle and pedestrian traffic management. Please continue to exercise caution when approaching these active work areas to minimize risks to personal safety, and to avoid any interference with construction.

Please know that we remain committed to prioritizing public health as well as the health of employees and contractors. National Grid has taken a number of steps to modify our business practices and daily operations to protect the communities in which we work. We have enacted additional policies and guidelines for our field and office personnel that are in line with the Commonwealth’s Guidelines and Procedures for construction as well as the Centers for Disease Control and Prevention’s guidelines.

As always, if you have questions about any of our current or upcoming work, please feel free to contact a member of our project outreach team by emailing us at, or by calling our project hotline 1-844-646-8427.

*Please note, due to the complexities of outdoor construction, schedule is subject to change.


Project Overview

WCAT, National Grid Cable Project in Wakefield - Construction in September 2019

Project Need, Benefits, and Route Information

Construction Process Information

Wakefield Project Fact Sheet.

Typical construction equipment involved in underground construction of this nature include, but are not limited to: excavators, dump trucks; crew cab pick up trucks; vacuum trucks; and portable generators

A strong electrical transmission system is vital to our region’s safety and economic prosperity. To improve reliability and address growing electricity demands identified by ISO-NE, National Grid and Eversource have teamed up to implement the Greater Boston and New Hampshire Solution, comprised of various projects in Massachusetts and New Hampshire.

One of the proposed projects is the Woburn to Wakefield Line, a new 345-kilovolt (kV) underground transmission line that will connect Eversource’s Woburn Substation in Woburn and National Grid’s Wakefield Junction Substation in Wakefield. The proposed line will extend approximately 8.5 miles between two existing substations, passing through Woburn, Winchester, Stoneham, and Wakefield, MA. The project also includes improvements within the existing fence lines of the Woburn and Wakefield Substations.

Eversource will be constructing the new line from the Woburn substation through Woburn, Winchester and Stoneham. National Grid will complete construction from the Stoneham/Wakefield border to the Wakefield Junction Substation.
