Mystic to Woburn Transmission Line Project
Important Construction Update Regarding Construction Activity at Wedgemere Station


February 7, 2022


Eversource construction crews will return to your neighborhood to resume construction activity for the Mystic to Woburn Line Project. This notice serves as a follow-up to our update construction notice delivered early-September. Please know that Eversource remains committed to prioritizing public health as well as the health of employees and contractors.

We’re Always Working to Serve You Better

Starting Tuesday, February 8th, crews from Middlesex Construction excavate through the Wedgemere parking lot. On Monday, February 14th, crews from Middlesex Construction and Angelica Boring will utilizing a horizontal boring method called “jack and bore” to install the underground transmission line beneath the Wedgemere Station railroad tracks.

When working under or near railroad tracks, the Massachusetts Bay Transportation Authority (MBTA) requires work to be performed non-stop until completion. As a result, the jack and bore process underneath the tracks, requires a continuous operation (24-hours a day). This will be performed by Angelica Boring and we estimate this to last up to seven days. Our continuous dewatering system will remain in place as the electrical conduit is installed under the tracks and while transitioning out of the excavated pits on each side of the Wedgemere Station.

While Angelica Boring begins the continuous, operation beneath the railroad tracks, crews from Middlesex Construction will excavate trench across the Wedgemere Station parking lot during regular work hours (Monday through Friday between 7 a.m. and 5 p.m.).

What You Can Expect

  • Reliable Service: Be assured that this work will not interrupt electric service to your property.
  • Proper Identification: All people working on this project carry identification.
  • Project Website: We also maintain a project website at https://www.eversource.com/content/Mystic-Woburn-Project.
  • Where We Will Be Working: Construction activity will take place on the south side of Bacon Street in the Wedgemere parking lot and within a parcel of land between the railroad tracks and the Aberjona River.
  • Traffic Management: We coordinate closely with the Winchester Police Department and town officials to maintain a safe and effective flow of traffic around project work areas. Parking will be restricted within some areas of the Wedgemere parking lot. Signage will be clearly posted in advance.

Starting Tuesday, February 8th, crews will excavate through the Wedgemere parking lot in two sections (map below for reference). While excavating section 1, vehicles will access Wedgemere Station through the northern entrance. While excavating section 2, across the northern entrance, vehicles will access Wedgemere Station through the southern entrance.

Construction Hours:

− General Work Hours: Work will occur in this area Monday through Friday between 7 a.m. and 5 p.m.

− Extended Work Hours: As noted above, the jack and bore work near and under the railroad will be conducted 24-hours-per day until completion and is expected to last seven days.

Construction Activities Project construction will include the following activities:

  • Mobilizing boring equipment.
  • Drilling approaching and under the railroad tracks. (7 days)
  • Installing underground pipe.
  • Removing soil and material disturbed during operations.
  • Areas will be temporarily restored once the jack and bore work is complete.

Project Completion: All remaining pipe installation will occur between Mystic Valley Parkway and Winslow Road. We expect to complete the underground vault and pipe installations in your area in 2022. Cable (underground transmission line) installation and final restoration will be completed in 2022.
