HUDSON RIVER TEST BORINGS FOR THE NEW NY BRIDGE COMPLETED

The New York State Thruway Authority and Tappan Zee Constructors, LLC (TZC) have announced that test boring operations in the Hudson River have been completed. The borings in the river are part of the pre-construction geotechnical work that began in late March. Crews will, however, continue test borings on land in both Rockland and Westchester and continue installing bridge monitoring devices in the Hudson River as part of the pre-construction engineering.

Work continues 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.

Environmental monitors continue to be installed in Rockland County as the 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 www.NewNYbridge.com.
