Work on the Park Avenue Viaduct, a critical Metro-North corridor in Upper Manhattan, has been completed 60 months ahead of schedule and $195 million under budget. The 133-year-old viaduct carries four Metro-North tracks above Park Avenue, from the Park Avenue Tunnel at East 97th Street to the Harlem River, supporting roughly 750 trains and 260,000 passengers daily. “The Park Avenue Viaduct replacement is proof that modernization doesn’t have to come at the expense of great service,” Jamie Torres-Springer, president of MTA Construction and Development, said. The project is a central component of the MTA’s broader efforts to modernize the Grand Central Artery, which includes the Grand Central Terminal train shed, Park Avenue Tunnel and Park Avenue Viaduct. Work on the viaduct also builds upon the ongoing redesign of Park Avenue led by the city’s Department of Transportation.
