WPCNR TAPPAN ZEE BRIDGE NEWS . From the New York State Thruway Authority. July 15, 2013:

Beginning today, Tappan Zee Constructors, LLC will install the first test piles for the New NY Bridge.

The test pile operations will be conducted over the next three months at proposed locations for pile foundations. Work will start at the main span footings.  Piles will be placed by utilizing both vibratory and impact installation techniques.  The test pile program will verify subsurface conditions in preparation for the construction of the bridge’s permanent foundation. 

Multiple crews will conduct night time boring operations along I-87/I-287 in both Westchester and Rockland Counties.  The night time operations are necessary due to lane closure restrictions during day time hours that are in place to keep traffic flowing over the current bridge. Boring operations will begin at exit 10 in Rockland County and move west into Westchester County.

Ongoing operations

–          Temporary Westchester trestle construction including pile driving on weekdays from 7 a.m. to 7 p.m.

–          Survey inspections on existing bridge

–          Rockland environmental monitor installations continue

–          Geotechnical land borings

–          Mobilization at the exit 10 staging area

–          Support for river-based work from the Rockland shoreline

Rockland:

Night time boring operations to investigate subsurface soil conditions will be conducted in the southbound shoulder of I-87/I-287 and will require a temporary right lane closure between exit 10 and the existing bridge from 9 p.m. to 6 a.m. beginning Monday, July 15 through Thursday, July 18.
