Project Description

The Henry Hudson Bridge is a steel arch toll bridge in New York that spans 840 feet over the Spuyten Duyvil Creek. Connecting Spuyten Duyvil in the Bronx to Inwood Hill in Manhattan, New York. The Project involves the Design-Build services for the Henry Hudson Bridge.

Constructed in 1936, the concrete substructures have been exposed to harsh environmental factors for 80 years, which has led to the acceleration of concrete deterioration as a result of alkali-silica reaction (ASR). The skewbacks, viaduct bent pedestals, and Lower Level North Abutment pilasters require rehabilitation to extend the remaining service life of the substructures and the Henry Hudson Bridge. The project scope includes installation and engagement of an Alternate Load Path (ALP) System utilizing high capacity deep foundation(s) at skewbacks, encapsulation of concrete skewbacks with new concrete encasement, replacement of North and South Viaduct Piers (bent pedestals) substructures, replacement of Lower Level North Abutment pilasters, and design/install/operate/maintain a structural health monitoring system during construction operations and following Substantial Completion for a period of two years.
