Goethals Replacement Bridge
(Twin Bridges)

The new twin 900-ft main span cable-stayed bridges between Staten Island, NY, and Elizabeth, NJ, replace the 85-year-old cantilever truss Goethals Bridge, which was functionally obsolete. Carrying three lanes plus inner and outer shoulders of Interstate 278 over the Arthur Kill strait in each direction, a walkway for pedestrians and cyclists is also included on the westbound span.

The bridge provides critical access for commuters and freight traffic. The project included design and construction of over 200 large-diameter rock-socketed drilled shafts to not only support the massive structures, but also resist the consequences of liquefaction and associated lateral spreading kinematic forces. To help inform the design and enhance optimization and economy, multiple static axial load tests were performed using the bi-directional embedded jack method. Multiple lateral load tests were also performed and included both static and lateral Statnamic test methods.
