For immediate release: October 18, 2013


Tappan Zee Constructors, LLC (TZC) began formal construction of the New NY Bridge on Wednesday, October 16 with installation of the first permanent piles that will comprise the bridge’s foundation. Pile driving will be limited to the hours of 7 a.m. to 7 p.m. on weekdays and, occasionally, from 12 noon to 7 p.m. on Saturdays.

The first of several highly sophisticated construction cameras has been installed and can be accessed at, under the ‘Construction Cameras’ icon. The public can stay up-to-date on the progress of the New NY Bridge with views from this construction camera and the interactive archive calendar.

On Monday, October 21, one northbound right hand lane and shoulder on I-87/I-287 near exit 9 in Tarrytown will be closed from 10 a.m. to 3 p.m. for drainage surveys. Tappan Zee Bridge toll plaza lane 12 on southbound I-87/I-287 will be closed on Tuesday, October 22 and Wednesday, October 23 from 11 a.m. to 2 p.m. for drainage surveys. On Thursday, October 24, one northbound right hand lane and shoulder on I-87/I-287 near exit 10 in South Nyack will be closed from 10 a.m. to 3 p.m. for drainage surveys. One northbound right hand lane and shoulder at the same location will be closed from 10 a.m. to 1 p.m. on Friday, October 25 for drainage surveys. TZC will also conduct maintenance ramp modifications on Monday, October 21, from 7 a.m. to 3:30 p.m. and on Thursday, October 24, from 9 a.m. to 2 p.m. near the Rockland Bulkhead.

Additionally, utility work will continue on River Road in South Nyack. This work will be performed from 6:30 a.m. to approximately 6 p.m. for the next few weeks and has been coordinated with and approved by the Village of South Nyack. The work will reduce the roadway to one lane during daytime hours and flaggers will be onsite to safely direct motorists on River Road.  During non-work hours, the road will have temporary coverings in place that may create uneven surfaces. Motorists and bicyclists should slow down and use extreme caution in the area.

Mariners should be aware that TZC will be installing piles in the vicinity of the side channels. Both temporary and permanent piles are illuminated at night. New temporary navigational lights have been installed to further define the 600’ navigation channel under the main span.

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.
