Total Design & Construction Support Services for Replacement of Bruckner Expressway over Westchester Creek, Unionport Bridge

The Unionport Bridge is a moveable bridge with a double-leaf trunnion bascule supporting Bruckner Boulevard over Westchester Creek in the Bronx, New York. The average daily traffic on the bridge is approximately 50,000 vehicles per day. The main structural members of the bascule span framing were found to be severely deteriorated in a NYCDOT Biennial Inspection, resulting in the decision to perform a total replacement of the bridge. The general scope of work includes construction of a new bascule structure, realignment of the approaches with new overhead connector ramps, mechanical and electrical systems, operator house, and fender system.
