TZC: Dredging Activities Move Forward (USA)

Dredging Activities Move Forward

Tappan Zee Constructors, LLC will continue utility work on River Road in South Nyack.

This work will continue through November and will involve reducing the roadway to one lane during daytime hours.

During non-work hours, the road will have temporary coverings in place that may create uneven driving surfaces.

Construction of the Rockland County trestle will continue and 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, from 12 noon to 7 p.m. on Saturdays. The trestle is a work platform that will 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.

Impact pile driving will continue as part of the ongoing test pile program through October at various future pile foundation locations, during the same timeframe as above.

The test pile program will verify subsurface conditions and test structural load capacities in preparation for construction of the new bridge’s permanent foundation.

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.
