TARRYTOWN - A viewer tells News 12 Westchester that some of the lights on the Tappan Zee Bridge went out Wednesday night.

The viewer says the lights from the center of the span leading to Westchester went out at around 11 p.m.

Elmsford resident John Morandi drove over the bridge Wednesday night and says he did not see anything wrong, but the Thruway Authority tells News 12 Westchester that there was a problem.

A spokesperson for the Thruway Authority says they will monitor the lights throughout the evening and electricians will be on call in case something happens again.
