For immediate release: September 6, 2013


Tappan Zee Constructors, LLC will begin utility work on River Road in South Nyack the week of Sept. 9. This work will continue through November and will involve reducing the roadway to one lane during daytime hours. During off hours the road will have temporary coverings in place that may create uneven driving surfaces. Motorists and bicyclists should slow down and use caution in the area.

Construction of the Rockland County trestle will continue and include daytime pile driving to install the temporary foundation piles needed to support the platform. Pile driving will be limited to a maximum of 7 a.m. to 7 p.m. on weekdays and, occasionally, from 12 noon to 7 p.m. on Saturdays. The trestle is a work platform that will support a crane for the construction of the westernmost section of the new bridge. The 1200-foot long platform helps reduce the amount of dredging required.

Impact pile driving will continue as part of the ongoing test pile program and will continue through October at various locations for future pile foundations during the same timeframe as above. The test pile program will verify subsurface conditions and test structural load capacities in preparation for construction of the new bridge's permanent foundation.

The U.S. Coast Guard has issued a revised Notice to Mariners with updated safety information, including a request that boaters use the main channel, reduce wake and use extreme caution while transiting the area in the vicinity of the Tappan Zee Bridge.

The Coast Guard boating safety information can be found on the project website,, under the boating safety icon.

On Monday, Sept. 9, and Tuesday, Sept. 10, one southbound right hand lane and shoulder on I-87/I-287 between exit 11 and the Tappan Zee Bridge will be closed from 10 a.m. to 3 p.m. for shoulder work. On Wednesday, Sept. 11, and Thursday, Sept. 12, one northbound right hand lane and shoulder on I-87/I-287 between exit 8 and exit 9 will be closed from 10 a.m. to 3p.m. for shoulder work.
