TZC is working closely with all appropriate authorities on the investigation, including the New York State Thruway Authority and the New York State Department of Environmental Conservation.

The incident began at approximately 6:45 [Tuesday, December 16] when the first silo collapsed and then at approximately 10 am the other two connected silos collapsed onto the barge deck.

No one was injured.


Tappan Zee Constructors (TZC), the group of contractors responsible for the New NY Bridge project, shut down one of its floating concrete production facilities Tuesday after a malfunction caused three of its silos to collapse.

Westchester police authorities reported that there were no consequential injuries onboard the barge, which was located off the Tarrytown shore north of the bridge.

“All workers are safe and all other construction work will continue on the project,” said TZC Spokesperson Carla Julian in an email, adding that representatives from the Department of Environmental Conservation as well as engineers from TZC and New York State Thruway Authority were on the scene assessing the situation Tuesday afternoon.

The floating concrete plant arrived at the Tappan Zee in recent months and was installed to produce over 300,000 cubic yards of concrete for the bridge’s new twin-span.

Julian also said that an investigation regarding the incident is underway, but declined to comment on the matter. In the meantime, it remains unclear if the incident will have an impact on the construction project’s schedule.

“Safety and environmental stewardship are our top priorities as we continue to investigate this incident,” Julian said.
