New York – a metropolis of challenging bridge expansion joint applications

The New York metropolitan area is a treasure trove of spectacular bridges – structures of great cultural significance and remarkable engineering value. Many of these bridges are very long, with long main spans, and thus require expansion joints that can accommodate correspondingly large movements at each end. The challenges associated with meeting the expansion joint needs of such structures are illustrated with reference to iconic bridges including the Verrazano Narrows Bridge, the Bayonne Bridge and the new Tappan Zee Bridge. The paper thus illustrates the importance of suitably engineered solutions for key component requirements in creating and maintaining the extraordinary structural heritage of a city like New York.
