Tappan Zee Constructors, LLC (TZC) is one step closer to completing the twin-span crossing as the new bridge’s westbound towers reach their ultimate height, 419 feet above the Hudson River. Crews are putting the finishing touches on the upper sections of the towers and removing the blue jump forms when the operations are complete. TZC is scheduled to complete all four westbound towers within the coming weeks.
While the large and powerful I Lift NY super crane continues to raise enormous, 410-foot sections of steel above the Hudson River, a far smaller and swifter machine, called a derrick crane, is hard at work on an equally important task – installing hundreds of road deck panels to form the base driving surface of the bridge.
As the New NY Bridge project continues to makeremarkable progress above the Hudson River, crews are installing several safety features on the crossing.
These features are the result of the project’s close collaboration with local and regional first responders during the bridge’s design development phase.
Prior to the start of New NY Bridge construction in 2013, Rockland and Westchester residents living near the project site voted overwhelmingly in favor of new permanent barriers to reduce highway traffic noise. Today, progress on the barriers is readily apparent in South Nyack.
The first full closure of the main navigational channel occurred this September. Approximately 70 closures are anticipated through the end of 2017 as project crews install new sections of structural steel and road deck panels between the towers of the new crossing.
The new twin-span bridge will have eight general traffic lanes – four in each direction. Space will also be provided for disabled vehicles, emergency responders and express buses and/or bus rapid transit. There will also be a shared-use path for bicycles and pedestrians.
