Tappan Zee Constructors, LLC (TZC) is scheduled to begin impact pile driving as part of the ongoing test pile operation this week. The test pile installation will continue over the next two to three months at the proposed locations of the foundations for the New NY Bridge. The test pile program will verify subsurface conditions in the river and the structural capacity of the pilings.
Under the Final Environmental Impact Statement, the hours of impact pile driving are restricted to 7 a.m. to 7 p.m., Monday through Friday and 12:00 noon to 7 p.m. on Saturday. There is no impact pile driving allowed at night or on Sundays. Noise monitors are in place along the Rockland and Westchester shorelines and the data is available at www.NewNYBridge.com.
Construction of the New York State Thruway’s temporary dock at the Rockland Maintenance facility on River Road in South Nyack will begin the week of July 29. TZC will reconstruct a maintenance dock that was damaged during Superstorm Sandy. This new dock will allow the Thruway to continue its normal maintenance work on the existing Tappan Zee as the construction activities for the New NY Bridge get underway.
Orange and Rockland Utilities will install new utility poles near River Road in South Nyack to support utility relocations which are needed for the New NY Bridge project. These operations may require temporary lane closures and will be performed by the utility.
