A structure that symbolizes US bridge engineering of the 1930s, the Pulaski Skyway, which links Newark to Jersey City has been partially closed as it undergoes a considerable rehabilitation - the largest in its history. The project was a perfect opportunity for the Federal Highway Administration (FHWA) and the New Jersey Department of Transportation (NJDOT) to take full advantage of the technical benefits offered by Ductal® Infrastructure joint fill over the 5.5km long bridge from Newark Airport to the Holland Tunnel.

The rehabilitation of Mauves-sur-Loire bridge consists in substituting the existing deck (3,500 m²) made of brick vaults with a thin deck made of thin precast UHPFRC slabs.
