The newly constructed Governor Mario M. Cuomo Bridge is a twin-span, cable-stayed bridge crossing the Hudson River connecting Nyack, Rockland County and Tarrytown, Westchester County. The new three-mile long bridge was built to replace the original Tappan Zee Bridge. The new bridge is the first cable-stayed bridge to cross the Hudson River and is the longest in New York State. The bridge carries I-87/I-287 and the New York State Thruway across the Hudson River. It has eight automobile lanes, two dedicated bus lanes and a 3.6 mile 12-foot wide bicycle/pedestrian shared use path. The bridge fully opened to traffic in 2018.

CVA provided construction inspection support for this high‑profiled $3.9 billion bridge replacement project. Services included performing a detailed inspection including asphalt inspection; cast-in-place barrier inspection and sign-offs for concrete placement acceptance; installation of concrete maturity and temperature measurement sensors; fresh concrete sampling; slump tests, spread tests and unit weight tests. Air content tests were performed using pressure, gravimetric and volumetric methods. Test specimens were prepared in the field. Inspectors took field measurements, data collection for final estimates and progress reports, and performed other construction activities. Our services included verifying that the contractor’s work conformed to contract documents. Record plans were prepared showing all changes from contract plans. All records were kept in accordance with the Manual of Uniform Record Keeping (MURK).
