Bayonne Bridge: Raising the Roadway

Abstract

The Port Authority of New York & New Jersey's Bayonne Bridge crosses the entrance to the Ports of Newark and Elizabeth, New Jersey. The longest steel truss arch span in the world when it opened in 1931, the bridge was designed by Othmar Ammann. To maintain the economic vitality of the ports, the original 46 m navigational clearance needed to be raised to 65.5 m to accommodate mega container ships passing through the newly widened Panama Canal. Precast concrete segmental construction was used along with an innovative staged construction approach to avoid long term bridge closures and to expedite the construction schedule. The new navigational clearance was attained in 2017 and project completion occurred in mid-2019.
