NEW YORK – The Metropolitan Transportation Authority replaced the first section of the 130-year-old Park Avenue Viaduct in Manhattan without disrupting Metro-North service over the weekend, the transit agency said yesterday.
The Park Avenue Viaduct carries four Metro-North Railroad tracks and serves all Metro-North trains traveling into and out of Grand Central Terminal, totaling 750 trains every weekday.
This past weekend’s operation utilized two gantry systems which extend over the viaduct to remove and replace the existing concrete and steel bridge deck with new prefabricated bridge units, weighing around 190,000 pounds each.

Phase 1 of the project, extending from East 115th Street to East 123rd Street along Park Avenue, includes replacement of the existing steel structure as well as new tracks, power, communications, and signal systems. Substructure construction to replace the viaduct’s foundations and columns began in September 2023 and construction for Phase 1 will continue through 2026. . . .
