Watch How Tappan Zee Bridge’s Main Span Towers Will be Constructed
Construction of the new Tappan Zee Bridge is halfway done.
Work on the massive $4-billion project has reached the 50 percent mark two years after it started, Tom McGuinness, construction compliance engineer for the New York State Thruway Authority, said Wednesday during a media boat tour of the 3-mile site.
The New NY Bridge’s iconic 419-foot main span towers will be constructed utilizing a unique type of self-climbing concrete “jump forms.”
