Construction of the Governor Mario M. Cuomo Bridge began in 2013 and the bridge fully opened to traffic in 2018. At the time of its construction, it was the single largest bridge project in New York’s history.

Innovative Construction Efforts
Design-builder Tappan Zee Constructors (TZC) utilized modular construction to create large sections of the bridge’s foundations, roadway and superstructure on land. This allowed TZC to safely prepare massive segments of the bridge off-site ahead of time, with some steel sections measuring up to 410 feet in length.
I Lift NY Super Crane
TZC was able to install these bridge elements thanks to its largest crane, dubbed I Lift NY. The enormous crane used a 328-foot lift arm, which is capable of raising up to 1,900 tons of material — the equivalent of 12 Statues of Liberty at once. The extraordinary lifting power of I Lift NY helped shorten construction time by months from original estimates and reduced project costs by millions of dollars. The crane also helped dismantle and recycle the old Tappan Zee Bridge.
