Mariners should be aware that Tappan Zee Constructors, LLC (TZC) will be installing permanent piles in the vicinity of the side channels under the existing bridge. 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. All boaters are advised to use the main channel, reduce wake and use extreme caution while transiting the area. If necessary, the Coast Guard in the future may temporarily prohibit all vessel traffic in the RNA for safety purposes. The Coast Guard boating safety information can be found on the project website under the “Boating Safety” icon.
