Dyer Avenue Bridge Deck Replacement – New York, NY

Project Name: Dyer Avenue Bridge Deck Replacement (Dyer Avenue & 31st Street)

Date of Project:  May 2016 Completion

Project Description: This project involved the full concrete deck replacement, steel repairs, abatement and painting of the Dyer Avenue Bridge over the western approach to Penn Station in New York City. The project also included shielding over sixteen active Amtrak and LIRR main line tracks and overhead catenary lines. Built in 1955, the three-span Dyer Avenue Bridge spans over Amtrak and the LIRR tracks. It consists of steel girders and transverse floor beams that support a deck of prestressed panels. In order to satisfy the project’s requirements of not altering the final grade and not increasing the weight of the deck but also upgrading to an LRFD design, Stantec designed precast concrete-filled steel grating panels as the deck replacement system. 

Additionally, as a major entrance/exit from the Lincoln Tunnel, it was required that the roadway should be opened for traffic every morning. As a result, rapid-setting concrete was employed for all of the cast-in-place concrete pours. The construction procedure included removing two deck bays, placing the replacement sections and locking them into place via studs/rapid-setting concrete, allowing traffic on the bridge as soon as one hour after the concrete placement.
