The Bayonne Bridge connects the City of Bayonne, NJ with Staten Island, NY. After its completion in 1931, the Bayonne Bridge was the longest steel arch bridge in the world, but today it sits in fifth place.
In 2013, prompted by the expansion of the Panama Canal, a $743.3 million project was awarded to raise the bridge deck within the original steel arch in order to accommodate larger post-Panamax class ships. The significance of this project cannot be overvalued as fully 12 % of all US-bound international container ships currently pass under the Bayonne Bridge.
To support the newly raised deck, mageba is supplying 158 RESTON-DISC bearings. All of the approach span bearings are being specially fabricated with the capability to be temporally locked against longitudinal movements during the construction phase, but allowing free movement after construction is completed.
The new bridge deck will also be equipped with 18 TENSA-MODULAR expansion joints, designed with up to 6 gaps to accommodate 17.7 in (450 mm) of movement, and 4 TENSA-FINGER sliding finger joints to accommodate 31.5 in (800 mm) of movement. Additionally, mageba is supplying sliding plate expansion joints for the shared use pedestrian and cycle paths.
