Congress Street Substation

Construction Process

This unique location on the bank of the Pequonnock River in Bridgeport, bordered by the CT Detention Center and the Metro North Railroad, as well as the busy downtown of Bridgeport, presents several unique construction challenges.

These include water-front construction, which required the installation of a cofferdam and a trestle platform to facilitate access for the heavy machinery and equipment; work within the energized substation and under live transmission lines, as the Congress Street Substation continues feeding customers during construction; environmental restrictions that necessitated the operation of on-site water treatment facilities; and rigorous noise and vibration monitoring program.
