text: In 2004, the police forces of both the PANYNJ and the NYPD announced concerns that the proposed One World Trade Center would be too close to the West Side Highway and thus vulnerable to car bombs. This prompted a total redesign of the tower and the relocation of its site away from the highway.
  There used to be four West Street pedestrian bridges, two of them erected after the September 11 attacks. A below-grade crossing of the West Side Highway connecting the Brookfield Place (formerly the World Financial Center) complex and the Concourse level of the World Trade Center opened in October 2013, allowing the pedestrian bridge adjacent to Vesey Street to be removed.
  On October 31, 2017, a man intentionally drove a pickup truck for a mile through the Hudson River Park's bike path, parallel to the West Side Highway, between Houston Street and Chambers Street, killing eight people and injuring at least 11. In 2022, Manhattan borough president Mark Levine proposed converting one lane of the West Side Highway into a bike path due to heavy traffic on Hudson River Park's bike lane.
  Major intersections
  Despite mostly being a boulevard, with many at-grade intersections and traffic lights, some of the intersections are given exit numbers.
