Norwalk Bridge Transmission Relocation Project
Why Did We Do This Project?
Connecticut Department of Transportation (CTDOT) is rebuilding the WALK Bridge (railroad bridge) that crosses the Norwalk River to ensure continued railroad operation along the vital Northeast rail corridor.
As part of this work, we relocated and energized the two electric transmission lines that span the top of the bridge. This work was necessary to help keep the power flowing in Norwalk.
On July 31, we held an event at the city’s Veterans Memorial Park, overlooking the Norwalk River, to mark the completion of our portion of the work. Approximately 60 guests attended, including community project partners, representatives from CTDOT and the City of Norwalk, and State Senator Bob Duff.
Where Was The Work Done?
We worked closely with Norwalk officials, CTDOT and other stakeholders since 2016 to develop a route that meets all required electrical reliability standards, limits environmental and community impacts, and could be built at a reasonable cost. Several potential routes for the relocation of the lines were reviewed.
Project construction was completed and placed in-service in May 2025 and included transitioning the two existing overhead transmission lines to underground near the Norwalk Police Department. The lines continue beneath the police station parking lot and down Elizabeth Street, to an area off Water Street.
From Water Street, the lines continue beneath the Norwalk River via horizontal directional drilling (HDD) to an area on Fort Point Street near the entrance of Veteran’s Memorial Park.
The lines continue beneath Fort Point Street and reconnect to the overhead lines along the railroad corridor in the vicinity of the Fort Point Street bridge.
To facilitate transitioning the overhead lines to underground, new steel monopole structures were installed near the railroad corridor in the vicinity of the Norwalk Police Station and the Fort Point Street bridge.

Community Outreach
We have made a concerted effort to engage town officials, residents, businesses and other stakeholders to inform, answer questions and listen to concerns about the project, beginning with municipal briefings and community outreach efforts.
A public open house was held on November 13, 2018, at the Norwalk City Hall Community Room to share information about the project. Residents and businesses had an opportunity to ask questions and provide feedback.
