Today many are surprised to learn that cars and buses used to run through Washington Square for much of the mid-20th century. In fact, the large flat area of the park around the fountain and the arch is a vestige of the time when motor vehicles used the park as a turnaround.

Jane Jacobs was not a fan of the automobile and its impact upon cities and neighborhoods. Along with her friends and neighbors, she waged the fight to get cars and buses out of the square, staging protests, gathering petitions, and lobbying city officials. Not only did the City not want to ban cars, they wanted to build an extension of Fifth Avenue through the park which would serve as an access route to the Lower Manhattan Expressway planned at the time, thus making Washington Square little more than the greenery surrounding a highway on-ramp.

Jacobs and fellow activist Shirley Hayes would have none of it. The City tried to entice them with “alternative” plans for allowing cars to remain in the park, including building a pedestrian passageway over the cars. But Jacobs, Hayes, and company persevered, and in the late 1950s, cars were banned from the park on a trial basis, and in the 1960s the ban was made permanent.
