Picture of the Day: Dredging at New NY Bridge

As part of the preparation for removing the existing bridge and completing the New NY Bridge project’s eastern landing of the southbound span, Tappan Zee Constructors (TZC) started the second stage of dredging operations this week.

Dredging is allowed during a three-month period from August 1 to October 31 in specified locations and will be conducted 24/7 to complete the required dredging during the short window.

The window was established to avoid impacting migration and spawning patterns of local sturgeon and other fish species.

These dredging operations, much smaller than the first stage, are 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 dredging will deepen the water level in the work zone by removing an estimated 187,960 cubic yards of sediment from the river bottom.
