Tappan Zee Constructors, LLC (TZC) crews helped rescue two boats that became unmoored near the Tappan Zee Bridge this past week.

On September 25, crews spotted a sail boat approaching the dredging area surrounding the Tappan Zee Bridge. After attempting communications and determining that no one was onboard, TZC’s safety team secured the boat and towed it to a tugboat. TZC then contacted the Rockland County Sheriff’s Office and the Coast Guard to track down the owner of the vessel. Later in the week, another unmoored vessel was secured by TZC and safely returned to its owners.

TZC crews will begin second shift operations on the river from 3:30 p.m. to 12 midnight on weekdays in preparation for permanent construction activities. This work is primarily support activities for the daytime pile driving operations and is limited by the project’s noise level restrictions. Pile driving will be limited to the hours of 7 a.m. to 7 p.m. on weekdays and, occasionally, from 12 noon to 7 p.m. on Saturdays. 

Construction of the Rockland County trestle will continue. This work will include daytime pile driving to install the temporary foundation piles needed to support the platform. 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.
From Monday, October 7 to Wednesday, October 9, one southbound right hand lane and shoulder on I-87/I-287 between exit 12 and the Tappan Zee Bridge will be closed from 10 a.m. to 3 p.m. for shoulder work.

Additionally, utility work will continue on River Road in South Nyack. This work will continue through November and will involve reducing the roadway to one lane during daytime hours. During non-work hours, the road will have temporary coverings in place that may create uneven driving surfaces. Motorists and bicyclists should slow down and use extreme caution in the area.

Mariners should be aware that TZC will be installing piles in the vicinity of the side channels. Both temporary and permanent pile are illuminated at night. Boaters should use extreme caution and only use the main channel for transiting the area. 

The U.S. Coast Guard has issued a revised Notice to Mariners with updated safety information, including the establishment of a Regulated Navigation Area (RNA) 300 yards north and 200 yards south of the existing Tappan Zee Bridge. All boaters are required to use the main channel, reduce wake and use extreme caution while transiting the area.

If necessary, the Coast Guard in the future may temporarily prohibit all vessel traffic in the RNA for safety purposes.

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