It took over a week for the Queens-Midtown tunnel to open to traffic after it flooded during Sandy.
On Tuesday, the MTA released a video from October 31 showing how much water flowed into it because of the superstorm. The transit agency also released photos of the flooding.
It was the first time the tunnel, which carries an average of 78,000 vehicles daily, flooded since it opened in 1940.
After dewatering its 1.6 mile tubes and making electrical repairs, it opened to bus traffic on November 6, cars on November 9 and trucks last Friday.
