Tappan Zee Constructors, LLC (TZC) will continue work on the New NY Bridge from Monday, June 30 through Thursday, July 3.
In addition, an enhanced marine law enforcement presence on the Hudson River will enforce the rules of the Regulated Navigational Area (RNA), reminding recreational boaters to stay away from construction equipment.
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.
On land, the installation of sheet piles, some measuring over 50 feet long, for the Rockland County landing will continue for several weeks. 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.
In Westchester County, crews will conduct utility relocations in the right lane of I-87/I-287 northbound between Interchange 9 and the existing Tappan Zee Bridge from 8 p.m. to 5 a.m. the week of June 30. The overnight operation requires the closing of the right-hand lane. The Thruway will remain open at all times.
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 Thursday.
Work will also continue on the Rockland temporary work trestle near the county shoreline, 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.
