Significance: The Niantic Bridge is a through girder bridge and consists of a movable span and four approach spans on stone masonry piers. The movable span is a chain-driven Scherzer rolling lift bascule span with overhead counterweight. It is significant as part of the transportation link in the shoreline route of the New York, New Haven and Hartford Railroad, and as an individual engineering solution to the need to provide dependable rail service while accommodating river navigation.
