Surveying work for the New NY Bridge Project will continue during the week of April 22 as engineering crews conduct more design surveys at various locations in Rockland and Westchester in the vicinity of the project, including the Westchester Haul Road location on New York State Thruway property in Tarrytown.

Installation of construction monitoring devices is planned at several locations this week. These devices, which monitor vibration, noise, and air quality, will be in place for the duration of the project to record construction activity impacts.  

Preconstruction surveys of properties located near the construction will begin next week. These operations will be conducted by engineering teams and will involve photographing the exterior and interior of structures. Tappan Zee Constructors is coordinating with the property owners for access.  

Preconstruction geotechnical investigations will continue as small barge-based drilling equipment will work at various locations throughout the project footprint in the Hudson River. The crews are conducting preconstruction geotechnical surveys to determine soil conditions where future piles will be installed for the new span. Noise levels from the equipment will be at a minimum. The river-based operations will run continuously 24 hours a day Monday through Friday and possibly Saturday.

Limited test-boring operations will continue on land under the existing bridge and just to the north at the proposed bridge locations. These operations are being conducted on Thruway property and will not affect traffic in any way. The work is scheduled to be conducted between the hours of 7 am and 5 pm Monday through Friday.

There are no land-based boring operations scheduled for the Rockland area for the week of April 22.
