Testing and inspection was recently completed on the Henry Hudson Bridge, a fixed steel-arch bridge in New York City with a double deck of two roadway levels, viaduct, and approach structures on both sides of the arch span, and spanning over 840 ft.
Originally built in 1935, Henry Hudson Bridge connects the northernmost tip of Manhattan and the Bronx, serving over 62,000 cars per day.
“Ensuring quality and public safety, and providing special inspection on the design, fabrication, and installation of the Henry Hudson Bridge’s new structural system, was our top priority,” Nagesh Goel, President and Co-Founder of AEIS, said in a statement. “Ensuring quality and integrity maximizes public safety for all."
AEIS was selected to provide special inspections on the design, fabrication, and installation of a structural system. This included providing an alternate load path to support the existing steel arch superstructure directly to the rock stratum below, bypassing the existing concrete substructures.
According to the Triborough Bridge and Tunnel Authority, various substructures of the bridge showed an Alkali-Silica Reaction (ASR) that caused cracking at the bridge’s four skewbacks, as well as 16 concrete bent pedestals and a lower-level north abutment. Unresolved, these issues could lead to long-term greater damage and safety concerns. Tutor Perini Corp. was hired as the general contractor in 2017.
The Henry Hudson Bridge connects Spuyten Duyvil in the Bronx with Inwood in northern Manhattan via NY 9A, or Henry Hudson Parkway. The bridge was named to memorialize the voyage of Henry Hudson, who anchored near the site in 1609. The Henry Hudson Bridge project is expected to be competed in late 2020.
