The 3.1-mile twin span cable-stayed bridge with angled main span towers is the single largest bridge construction project in New York’s history. The bridge will revitalize the existing Governor Malcolm Wilson Tappan Zee Toll Bridge that connects Rockland County to Westchester County over the Hudson River.

TZC received an executed contract and a notice to proceed (NTP) in January 2013. The project is currently underway, and the team has established offices in Tarrytown, New York.
