About the project
The Park Avenue Viaduct replacement project focuses on the elevated steel structure that carries four Metro-North Railroad tracks along Park Avenue between East 110th Street and the Harlem River Lift Bridge.
The Metropolitan Transportation Authority will replace or repair major segments of the Viaduct. Phase 1 entails the complete replacement of the Viaduct from East 115th Street to 123rd Street. Phase 1 construction is scheduled to begin in mid-2023 and continue through 2026.
All Metro-North trains along the Hudson, Harlem, and New Haven lines must travel on the Park Avenue Viaduct to get in and out of Grand Central Terminal. On a typical weekday, approximately 750 trains and hundreds of thousands of customers travel across the viaduct. Nearly half of the viaduct was constructed in the 1890’s.
We will replace major segments of the structure as quickly and safely as possible, while minimizing impacts to the surrounding neighborhood.
- Maintains public safety
- Makes the viaduct more resilient
- Reduce noise and vibration levels by using stronger materials
