Project Update
For immediate release: November 15, 2013
Residents and motorists now have a Rockland County-view of work at the site of the New NY Bridge with the addition of a third construction camera. The construction camera went live this afternoon at NewNYBridge.com, and joins two others that provide views from Tarrytown and the Tappan Zee Bridge, respectively.
Located on a hill overlooking the Hudson River in Upper Grandview, the newest construction camera offers a view of the existing span, as well as barges, equipment and the permanent piles that are currently being constructed.
The installation of permanent piles will continue at the site next week, as will “armoring” of the dredge channel. Armoring is a process that helps protect the water quality for marine life. Currently, TZC crews are layering sand and stone within the dredge channel to armor the river bottom in an effort to ensure sediment is not kicked up by construction vessels.
The creation of the first of four new permanent noise barriers is also underway in Rockland County and sections of the existing noise wall along northbound I-87/I-287 in the area south of exit 10 will continue to be removed next week. From Monday, Nov. 18 to Wednesday, Nov. 20, one northbound right-hand lane and shoulder on I-87/I-287 in the area south of exit 10 in Nyack will be closed from 10 a.m. to 3 p.m. for sound wall removal. A temporary noise barrier and noise monitors have been installed nearby and additional temporary noise barriers will be installed along a local access ramp and the New York State Thruway, after improvements are made to the ramp.
Mariners should be aware that 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’ 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.
