WESTCHESTER COUNTY, N.Y. -- The second stage of dredging on the Hudson River shoreline in preparation to remove the existing Tappan Zee Bridge will being on Saturday.
The upcoming dredging operation, much smaller than the first stage, is designed to create an access area for the I Lift NY super crane to remove sections of the existing bridge and build the southbound landing of the new bridge.
The process will deepen the water level in the work zone by removing an estimated 187,960 cubic yards of sediment from the river bottom.
Dredging is allowed during a three-month period from August 1 to October 31 in specified locations and will be conducted around the clock.
Once the second stage of dredging is complete, approximately two feet of gravel will be placed in the dredged channel to limit the stirring up of river sediment when working vessels traverse the area.
