New York completes Park Avenue viaduct 5 years early, $200M under budget and with no delayed trains

New York City's Metropolitan Transportation Authority completed construction work on the Park Avenue Viaduct five years ahead of schedule and $195 million under budget, all while managing to avoid delaying any trains during construction. 

As Noah Kolenda explains in an article in Mass Transit, "Since October 2023, the MTA reports that crews have replaced 196 bridge structures and more than 12,600 feet of railroad over 28 weekends without delaying a single train." The viaduct, built 133 years ago, carries roughly 750 trains and 260,000 passengers every day. 

The MTA says it is making major investments to infrastructure along the Grand Central Artery, much of which is over a century old. "Between updates along Park Avenue and the replacement of the Grand Central Terminal train shed, the MTA notes it is making $2.9 billion in capital investments to improve Metro-North service for generations to come."
