UPDATE 9/8/18: Authorities have delayed the opening of the second span of the Mario Cuomo Bridge, reportedly prompted by fears that the old Tappan Zee Bridge was in danger of collapse. Boat traffic was halted beneath the span.
New York State Thruway Authority Executive Director Matthew Driscoll issued a statement Saturday morning:
"In continued disassembly of the old Tappan Zee Bridge last night, a potentially dangerous situation developed where a piece of the old bridge has become destabilized and could fall. Given its proximity to the new completed span, out of an abundance of caution, motorists will remain in the current traffic configuration until a thorough evaluation by Tappan Zee Constructors is complete."
