New York’s Metropolitan Transportation Authority (MTA) is celebrating a crucial railway bridge replacement project that it says is $93m under budget and a whopping 51 months ahead of schedule.
The $590m first phase of the Park Avenue Viaduct Replacement Project used 128 bridge installations, replacing 8,240ft of track on the 132-year-old structure.
Halmar International installed a gantry system above the viaduct crossing Park Avenue, which let the team replace whole sections of the concrete and steel deck with prefabricated units.
Work took place over 19 weekends without disrupting the Metro-North train service.

Phase one of the project is 21 months ahead of its schedule, while work has begun simultaneously on the project’s second phase, making the entire development 51 months ahead.
The Metro-North railroad runs from New Jersey, through Manhattan, the Bronx and up to Connecticut.
Janno Lieber, MTA chief executive, said: “The Park Avenue Viaduct is a prime example of critical MTA infrastructure that had been left to rot for decades — but not anymore.
“Our 2025-2029 Capital Plan is all about bringing infrastructure into the 21st century, and we look forward to bringing the same innovative and cost-saving approach that has succeeded here to projects all over the system.”
