This infrastructure project involved major upgrades along W 33rd Street and the 11th Avenue Viaduct, including water main installations, new retaining walls, utility upgrades, bridge reconstruction, and elevated street grading—enhancing safety, accessibility, and support for ongoing development in the Hudson Yards area.

The scope of work includes the installation of 36” and 12” combined water mains and new fire hydrants; the placement of micro piles to support new retaining walls along the north curb; and the installation of new catch basins and manholes. Additionally, the project entails new electrical service connections for office towers under development on W 33rd Street.

• Raising the existing street to a legal grade elevation, 15 feet higher than current level
• Installation of new street lighting and traffic signal infrastructure
• Demolition of a portion of the 11th Avenue Viaduct and replacement with a newly constructed bridge, including abutments, expansion bearings, and micro piles anchored 10 feet into bedrock
• Construction of a new bridge deck using HP concrete per NYSDOT specifications
• Reconstruction of a section of the MTA Hudson Yards Park retaining wall
• Installation of new concrete sidewalks and pavement markings

This project supports vital urban infrastructure upgrades in one of New York City’s most active development zones.
