Crane topples across all lanes of travel on Tappan Zee Bridge; operator lands in river 

As traffic continues to ease up on the Tappan Zee Bridge following Tuesday’s crane collapse, investigators are still looking into what caused the 300-ton piece of machinery to topple over and block all lanes of traffic.

The crane had been supporting a vibrating hammer that was pile-driving when the giant boom collapsed, causing chaos and trapping motorists on the bridge for hours.

Gov. Andrew Cuomo says a full investigation is underway to find out what happened. President of Tappan Zee Constructors Terry Towle says the crane that failed was a new piece of equipment that was performing a routine task.

Accident investigators say the crane's maintenance records are key to the investigation, as is the experience of the crane operator.

Cuomo adds that he does not believe the crane collapse will affect the timing or construction on the opening of the New Tappan Zee Bridge.
