For immediate release: January 3, 2014


Due to severe weather conditions, Tappan Zee Constructors, LLC (TZC), suspended scheduled project operations for today and tomorrow, but a small crew remains on site to continuously monitor conditions and respond immediately to any weather-related issues.

Normal operations are scheduled to resume Monday, as crews continue construction of the foundation of the New NY Bridge with the ongoing installation of permanent piles.

Subsurface utility investigations will take place in Tarrytown the week of Jan. 6. To facilitate this operation, the northbound right-hand lane of the New York State Thruway (I-87/I-287) near the approach to the Tappan Zee Bridge in Tarrytown will be closed on Monday, Jan. 6 and Tuesday, Jan. 7, from 10 a.m. to 3 p.m.

From Tuesday, Jan. 7, through Thursday, Jan. 9, the northbound right-hand lane and shoulder of the Thruway (I-87/I-287) near exit 10 in Nyack will be closed from 10 a.m. to 3 p.m. The same section of roadway will be closed on Friday, Jan. 10, from 10 a.m. to 1 p.m., to allow for work on the northbound maintenance ramp.  

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 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 at under the “Boater Safety” icon.
