CUOMO BRIDGE /​ TAPPAN ZEE

CUOMO BRIDGE / TAPPAN ZEE

The Governor Mario M. Cuomo Bridge, replacing the original Tappan Zee Bridge, is one of the largest infrastructure projects in New York State history. Spanning the Hudson River between Westchester and Rockland Counties, the new crossing significantly improves regional mobility and reliability for millions of commuters and commercial vehicles.

The bridge carries approximately 50 million vehicles annually and alleviates congestion at one of the most critical river crossings in the region, delivering a modern, resilient transportation link just north of New York City.

Muñoz Engineering and Land Surveying, DPC, as a subconsultant to HNTB, provided surveying, office engineering, and research services for this massive design-build effort — one of the largest design-build contracts in the United States and, at the time of construction, one of the largest bridge projects in New York’s history.

Muñoz provided topographic survey and planimetric features surveying to locate the horizontal and vertical position of the above ground topographic features, and prepared two-dimensional plans and DTM files from the features located. Additionally, Muñoz provided construction compliance oversight–field support by performing verification of total and differential settlement monitoring of pile caps in the friction piling zone and the pile caps supported on rock immediately adjacent to the friction piles.

Muñoz also provided office engineering including commercial management support, reviewing key communications between the project team, the Design-Build team, the New York State Thruway Authority. Muñoz Engineers provided utility research, and worked with local governments for site plans, surveys, subdivision plans, and any other improvement plans that fall within the project limits.
