This Spring, Eversource construction crews will return to your neighborhood to continue construction activity for the Woburn to Wakefield Line Project. This project is designed to increase reliability of the electric grid in the area to meet growing demands for electricity. As we perform this necessary work, we are continuing to follow COVID-19 health and safety guidelines. Crews from McCourt Construction will be installing duct bank on Washington Street and Cross Street along with several manholes (vaults) on Cross Street. To prepare for this work, some work activities will be completed beforehand. Property owners will be notified in advance of work occurring in your area.

Traffic Management

We coordinate closely with the Winchester Police Department and town officials to maintain a safe and effective flow of traffic. We will maintain two lanes of traffic near the “jack and bore”. Lane closures and detours may be necessary during duct bank installation. Local access to property owners and businesses will be maintained along with large vehicle traffic.

Vehicle detours for Washington Street currently utilize the Sunset Road neighborhood. Vehicle detours on Cross Street currently utilize Forest Street. Local access to property owners and businesses will be maintained along with large vehicle traffic.
