6. 9/11 Closure
Following the attacks on September 11th, 2001, traffic in and out of New York City was put to a stop. For the next week, the Williamsburg Bridge remained closed to all except emergency vehicles. Afterwards, new restrictions were imposed on the bridge’s HOV lane as part of a large-scale effort to reduce congestions below 63rd street. The HOV-restrictions remained in place on the Manhattan bound side until November 2003.
