H&H is provided resident engineering and construction inspection services to rehabilitate the Henry Hudson Parkway Viaduct for New York City DOT. One section of the rehabilitation project consisted of repairs to the deck and steel elements of the viaduct superstructure in spans from West 72nd Street to West 82nd Street. The other section included the spans between 94th Street and 98th Street. Both sections involved extensive painting and were performed in coordination with the Amtrak force account. Work in this area also required coordination with NYCDPR, as Riverside Park surrounds the area.
The scope of work included abrasive blasting (lead abatement) and painting of approximately 1,400,000 sf of steel, rehabilitation, and replacement of structural steel, asbestos removal, rehabilitation of concrete deck and barrier, expansion joint replacement, and rehabilitation of the abutments, retaining walls, and column crash walls. Extensive agency coordination was required due to its proximity to Riverside Park, the Hudson River Greenway, and active Amtrak railroad tracks.
The Henry Hudson Parkway Viaduct is traversed by 129,000 motorists every day, so well-planned and efficient operations were critical to minimizing traffic disruptions. The work was highly visible to the residents and the thousands of people who utilize Riverside Park and the Hudson River Greenway. The resulting completed construction project provides state-of-the-art upgrades and an aesthetically pleasing new roadway that is visible from the Hudson River Greenway. It also lengthens the life of the structure and enhances safety.
