For immediate release: July 2, 2014


In observance of the Fourth of July, Tappan Zee Constructors, LLC (TZC) will not be working over the holiday weekend starting after the second shift on July 3. Work on the New NY Bridge will continue on Monday July 7.  TZC crews will continue to monitor and maintain the safety and security of the project site from Friday to Sunday.

In addition, an enhanced marine law enforcement presence on the Hudson River will enforce the rules of the Regulated Navigation Area (RNA), reminding recreational boaters to stay away from construction equipment. Marine units from Westchester County, Rockland County and the U.S. Coast Guard Auxiliary will be on patrol.  Boaters are urged to use extreme caution on the river especially during and after the Fourth of July fireworks displays and to transit the main navigation channel at all times. More New NY Bridge boater safety information, including the U.S. Coast Guard Notice to Mariners, and construction site maps, can be found here at  An interactive map showing vessel locations on the Hudson River is also available here for recreational and commercial boaters to get updated information on this very active construction zone. The GPS tracking map is for informational purposes and not intended for navigation. 

Mariners should be aware that TZC will continue installing permanent piles in the vicinity of the side channels under the existing bridge. Additional 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 as are all moorings, barges and other equipment.

On land, the New York State Thruway Authority’s Tappan Zee Bridge maintenance and operations base and New York State Police Troop T have moved from their Tarrytown offices at 333 South Broadway (Rt. 9) to a temporary facility near I-87 interchange 12 at 160 N. Route 303, West Nyack. The West Nyack building was previously vacant before being renovated by TZC. The Thruway facilities at 333 South Broadway in Tarrytown will be removed to make way for New NY Bridge project operations and eventually the new alignment for the new bridge. Once construction is complete in 2018, both Thruway Maintenance and the State Police will return to new and improved facilities in Tarrytown.

TZC will continue work on the Rockland County landing of the new bridge.  The work will last several weeks and include the installation of sheet piles, some measuring over 50 feet long.  These interlocking steel sheets will support the existing roadway during the excavation and construction process.  A large crane with a vibratory pile hammer will install the sheets, and be positioned behind a temporary concrete barrier in South Nyack.

Construction will continue in the Hudson River as crews continue the installation of the foundations for the New NY Bridge.  Work will include pile driving between 7 a.m. and 7 p.m., Monday through Friday and 12 noon to 7 p.m. on Saturday. 

A second shift of workers will also continue pile welding operations associated with permanent foundations.
Work will also continue on the Rockland temporary work trestle near the county shorelines, including pile driving to install the temporary foundations needed to support the platform. The trestles will support cranes for the construction of the western-most section of the new bridge.
