Following the successful completion of its phase one girder operations, the project’s largest crane has returned to familiar territory to help crews with road deck installation.
Tappan Zee Constructors recently completed the first two 419-foot towers of the iconic main span. Our new time-lapse video captures the evolution of the westbound (Rockland-bound) towers aided by the project’s blue self-climbing jump forms.
The New NY Bridge project has become a symbol for what the state can accomplish. Watch the new twin-span crossing take shape during the past three years in this new time-lapse video. From steel girders to concrete towers, from piles to road deck, from shoreline to shoreline, the transformation has been amazing.
The existing bridge has only seven lanes, some of which are narrower than the current standard width of 12 feet. The new bridge will have eight 12-foot-wide lanes. The wide shoulders of the new crossing will greatly reduce the traffic impact of disabled vehicles and accidents, which can cause massive tie-ups on the existing bridge. The incline over the main span will not be as steep, allowing large trucks to maintain consistent speed and reduce engine and braking noise. There will also be gently banked curves to help smooth traffic flow and reduce accidents as well as a cashless tolling system to eliminate the need for drivers to slow down or stop at a toll plaza. In addition, the new bridge is being built with the structural capacity to handle commuter rail, light rail, or bus rapid transit.
