WEST ROXBURY TO NEEDHAM RELIABILITY PROJECT

This construction project will improve the transmission system in the Boston area so customers will have reliable power to meet their growing energy needs.

At Eversource, we're always working to serve you better. For the West Roxbury to Needham Reliability Project, Eversource proposes to separate the overhead transmission lines on existing double-circuit towers on the right of way (power line corridor) between substations in the Boston neighborhood of West Roxbury and Needham, Mass.

The project route will cross about 4.5 miles between the Baker Street Substation in West Roxbury and the Needham Substation in Needham. The separation work will involve relocating 1.6 miles of the line onto new sets of structures on the rights of way in Boston, Dedham and Needham.

In Needham, the newly separated line will exit the overhead right of way on Valley Road and transition to underground. The underground line will then extend about 3 miles on the preferred route from Valley Road to Needham Substation.

ENERGY FACILITIES SITING BOARD (EFSB)

For an electric transmission line project, such as the West Roxbury to Needham Reliability Project, the Massachusetts Energy Facilities Siting Board (EFSB) Petition filing is part of the siting regulatory review process, as defined by Massachusetts state statutes.

On May 17, 2018, Eversource received approval from the EFSB to construct the West Roxbury to Needham Reliability Project. See the EFSB 16-02 Final Decision 5-17-18

Construction Updates

First, please know that Eversource takes every safety precaution while working in local communities, and that all people working on the construction project carry identification.

Eversource is committed to updating neighbors, businesses and the community about project activities, especially during construction. Please note that the project work will not interrupt electric service to homes or businesses.

Project construction began in June 2018 and is expected to be complete in mid-2019.

Work hours during construction will typically be 7 a.m. to 6 p.m., Monday through Friday, and 9 a.m. to 5 p.m. on Saturdays in non-residential areas. During the school year, work requiring detours along a school bus route will not start until 9 a.m. Due to unexpected weather or other circumstances, the work hours may be extended or performed on a Sunday.

Police officers will be stationed at every major intersection where construction is taking place. 

Week of September 10, 2018:

  • Crews continued placing temporary construction matting -- a flat surface to protect an area from construction activities and equipment -- between Gardner Street and Baker Street.
  • Crews continued removing vegetation and installing foundations between Gardner Street and Cutler Park.

Week of September 17, 2018:

  • Crews will continue placing temporary construction matting -- a flat surface to protect an area from construction activities and equipment -- between Gardner Street and Baker Street.
  • Crews will continue installing foundations between Gardner Street and Cutler Park.

Week of September 10, 2018:

  • Crews began installing foundations in Cutler Park.

Week of September 17, 2018:

  • Crews will continue installing foundations in Cutler Park.

Week of September 10, 2018:

  • On the MBTA right of way (line corridor) off High Rock Street, crews continued to excavate for the duct bank, which houses electric cables; and installed a manhole (a pre-cast iron vault).  
  • On South Street, crews continued to excavate to determine the presence of underground utilities.
  • On the right of way (power line corridor) off Valley Road, crews continued with removing vegetation, placing temporary construction matting -- a flat surface to protect an area from construction activities and equipment -- and began installing foundations.
  • In Cutler Park, crews began installing foundations. The portion of Blue Heron Trail that crosses the MBTA right of way will be closed through early December, due to construction.

Week of September 17, 2018:

  • On the MBTA right of way (line corridor) off High Rock Street, crews will continue to excavate for the duct bank, which houses electric cables.
  • On High Rock Street, crews will begin excavation for the duct bank. There will be a single lane closure, resulting in alternating traffic patterns.
  • On Valley Road, crews will begin excavation for the duct bank. The road will be closed except for local traffic.
  • On the right of way off Valley Road, crews will continue removing vegetation, placing temporary construction matting -- a flat surface to protect an area from construction activities and equipment -- and installing foundations.
  • In Cutler Park, crews will continue installing foundations. The portion of the Blue Heron Trail that crosses the MBTA right of way will be closed through early December, due to construction.

TRAFFIC MANAGEMENT PLANS

Working in consultation with town and state officials, including the Mass. Department of Transportation (MassDOT), Eversource has developed a set of Traffic Management Plans (TMPs) for each section of the West Roxbury to Needham Reliability Project.

The TMPs include conditions specific to routing as made by the EFSB in its final decision. The TMPs illustrate detailed site plans, showing underground line locations, hours of construction, area-specific traffic controls, and more.

Please note, TMPs are subject to change and may be updated.
