For Immediate Release: May 31, 2013


No new pre-construction activities are slated for the week of June 3.

Environmental monitors continue to be installed in Rockland County as the New York State Thruway Authority and Tappan Zee Constructors, LLC (TZC) finalize specific installation locations.  The monitors continually record noise, vibration and air quality for the duration of the project.  All readings can be viewed at

Test boring operations in the Hudson River continue as does work on the temporary Westchester trestle. The trestle is a work platform that will support a crane for the construction of the new bridge. The 1,000-foot long platform reduces the amount of dredging required and allows crews to work from the water and not from the Westchester shoreline. Work on the Westchester trestle will include daytime pile driving to install the temporary foundation piles needed to support the platform. Pile driving will be limited to the hours between 7 a.m. and 7 p.m. Monday through Friday.


Surveying, utility exploration and test boring work continues for the New NY Bridge during the week of June 3. The work being performed in the shoulder area of northbound I-87/I-287 will require a temporary right lane closure between Exit 9 and the toll plaza on Wednesday and Thursday from 10 a.m. to 3 p.m. There will also be a temporary right lane closure on southbound I-87/I-287 between the toll plaza and Exit 9 from 10 a.m. to 3 p.m. on Friday.


Mobilization work continues at Exit 10 where TZC will store materials for construction, trailers for work operations and equipment, and use the staging area for employee parking.

Support for river-based work from the Rockland shoreline will continue the week of June 3.
