Park Avenue Viaduct Reconstruction

Metropolitan Transportation Authority Construction & Development and Metro-North Railroad plan to replace major segments of the Park Avenue Viaduct between 115th Street and
132nd Street. The Park Avenue Viaduct is an elevated steel structure that was built in 1893 and carries four Metro-North Railroad tracks above Park Avenue in East Harlem. 98% of all Metro-North trains use the viaduct; 750 trains and 220,000 customers use the viaduct on a typical (Pre-Covid) weekday; the viaduct is a 1.25-mile-long steel structure (5 track
miles). The viaduct is the main artery that carries all riders to and from Grand Central Terminal and Harlem-125th Street Station.

The will be a state of good repair project which will completely replace the viaduct in two sections, 115th-123rd Streets and 128th-131st Streets.

All MNR East of Hudson trains must pass over the Viaduct to reach Harlem-125th Street Station and Grand Central Terminal – there are no alternate routes. The PAV is not in a state of good repair and current usage is well above the original design. The PAV is a single point of failure for East-of Hudson service without which the MNR cannot serve The Bronx, Manhattan, Westchester, Putnam, Dutchess, or Connecticut.

It is currently estimated that work could begin sometime in 2023 and would complete by 2025.
