Tappan Zee Constructors, LLC (TZC) will resume marine operations the week of Feb. 17, 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 will also continue on both shore lines and in the bridge assembly yard.
Mariners should be aware that 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-foot 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 yards north and 200 yards 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 NewNYBridge.com under the “Boater Safety” icon.
