DREDGING OPERATIONS AND TEST PILE PROGRAM IMPACT PILE DRIVING CONTINUE
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 the project website, www.NewNYBridge.com under the boating safety icon.
Dredging will occur over a three-month period from August 1 through October 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 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.
Impact pile driving will continue this week as part of the ongoing test pile program and will continue through October 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.
Ongoing geotechnical boring activities will continue to support the developing design for the New NY Bridge Project.
TZC will continue fencing and sidewalk work along River Road in South Nyack north of the existing bridge. This work is part of the bulkhead construction area and will be performed between 7 a.m. and 3 p.m. Monday through Friday. River Road will be limited at times to one lane with flag persons in place to control traffic safely.
