West Roxbury to Needham Reliability Project

Why Are We Doing This Project?

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

Where Is The Work Being Done?

Our crews are working 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.

The project route crosses about 4.5 miles between the Baker Street Substation in West Roxbury and the Needham Substation in Needham. The separation work involves 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 exits the overhead right of way on Valley Road and transitions to underground. The underground line will then extend about 3 miles from Valley Road to Needham Substation.

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.

Construction Updates

We take every safety precaution while working in local communities, and all people working on the construction project carry identification.

Project work will not interrupt electric service to homes or businesses.

Work hours during construction will typically be 7 a.m. to 5 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., unless authorized by the municipality. 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.
