Tappan Zee Constructors LLC (TZC) will resume marine operations this week, weather permitting, with crews continuing construction activity to install the foundations for the New NY Bridge. This includes the ongoing installation of permanent piles for the main-span towers, including pile driving between 7 a.m. and 7 p.m. on weekdays, and occasionally between noon and 7 p.m. on Saturdays.


Construction also will continue on both shorelines and in the bridge assembly yard.


TZC will continue installing permanent piles in the vicinity of the side channels under the existing bridge, weather permitting. Pile driving will take place between 7 a.m. and 7 p.m. on weekdays, and occasionally between noon and 7 p.m. on Saturdays. New temporary navigational lights have been installed to further define the 600-ft navigation channel under the main span. Both temporary and permanent piles are illuminated at night.


The U.S. Coast Guard has issued a revised Notice to Mariners with updated safety information, including the establishment of a Regulated Navigation Area (RNA)—300 yd north and 200 yd south of the existing Tappan Zee Bridge. The U.S. Army Corps of Engineers has issued a modified permit for additional temporary mooring locations during construction of the new bridge. All boaters are advised to use the main channel, reduce wake and use extreme caution while transiting the area. If necessary, the Coast Guard may temporarily prohibit all vessel traffic in the RNA for safety purposes. The Coast Guard boating safety information and the modified mooring permit map can be found on the project website at under the "Boater Safety" icon.


Ongoing operations include permanent pile installation; temporary Rockland trestle construction; Rockland access ramp modifications; support for river-based work from the Rockland shoreline; reinforcement steel preassembly at bridge yard; and survey inspections on the existing bridge.
