Work is scheduled to begin the week of August 26 on the Rockland trestle, which is the second temporary work platform to be constructed as part of the New NY Bridge Project.
The work will include daytime pile driving to install the temporary foundation piles needed to support the platform. Pile driving will be limited to a maximum of 7 a.m. to 7 p.m. on weekdays and, occasionally, on Saturdays from 12 noon to 7 p.m. The trestle is a work platform that will eventually support a crane for the construction of the westernmost section of the new bridge. The 1200-foot long platform helps reduce the amount of dredging required near the Rockland shoreline
Impact pile driving will continue as part of the ongoing test pile program and will continue through October at various locations for future pile foundations. This work will be performed from 7 a.m. to 7 p.m. on weekdays and, occasionally, on Saturdays from 12 noon to 7 p.m. The test pile program will verify subsurface conditions and test structural load capacities in preparation for construction of the new bridge’s permanent foundation.
Tappan Zee Constructors (TZC) will continue dredging operations in the Hudson River as part of the New NY Bridge Project. Dredging will occur through October 31 to avoid negatively impacting migration and spawning patterns of local sturgeon populations and other fish species.
Dredging crews will work 24/7 starting from the main navigation channel end of the dredging footprint towards the shoreline on both the Rockland and Westchester County sides of the bridge. The operations will deepen the river’s shallow water level in the work zone by removing sediment from the river bottom. The dredged materials are being properly disposed of at offsite locations.
The U.S. Coast Guard has issued a revised Notice to Mariners with updated safety information, including a request that boaters use the main channel, reduce wake and use extreme caution while transiting the area in the vicinity of the Tappan Zee Bridge.
