Union Square to Portland Street Distribution Project

Why Are We Doing This Project?

At Eversource, we're always working to serve you better. This work supports a proposed electrical distribution upgrade, connecting the Prospect Street Substation in Somerville to the existing distribution network in Cambridge. The Project is one of several designed to improve the reliability of the electric system serving Somerville, Cambridge, and the surrounding area.  This work will not disrupt your electrical service.

Where Is This Work Being Done?

This project includes the installation of 20 new underground vaults (manholes), and new in-street duct banks (a group of tubes to house electric lines) spanning an approximately one-mile route along Prospect Street in Somerville and Cambridge, MA and Harvard and Portland Streets in Cambridge.

Traffic Management

Eversource coordinates closely with municipal officials on effective traffic management throughout the project. At times, parking restrictions may be necessary and will be clearly posted in advance.  Construction crews will occupy a portion of the roadway, typically leaving the remainder of the road passable to motorists, cyclists, and pedestrians. When detours are necessary signage will be clearly posted for motorists. Please monitor this web page for updates on traffic management.

Eversource is committed to keeping neighbors, businesses and community members informed on project activities during construction.
