BRIDGE CONSTRUCTION: Dredging proceeds 24/7 at Tappan Zee Bridge site
Impact pile driving will continue through Oct. 31 for future foundations
Tappan Zee Constructors LLC (TZC) will continue 24-hour-a-day dredging operations in the Hudson River as part of the New NY Bridge Project.
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.
The Coast Guard boating safety information can be found on the project website (http://www.newnybridge.com) under the boating safety icon.
Dredging will occur over a three-month period from Aug. 1 through Oct. 31 to avoid negatively impacting migration and spawning patterns of local sturgeon populations and other fish species.
Dredging crews will work 24 hours a day, seven days a week starting from the main navigation channel end of the dredging footprint toward 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.
Impact pile driving will continue this week as part of the ongoing test pile program and will continue through Oct. 31 at various locations for future pile foundations. This work will be performed from 7 a.m. to 7 p.m. on weekdays and, at times, 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.
