4th Street is a street in Lower Manhattan, New York City. It starts at Avenue D as East 4th Street and continues to Broadway, where it becomes West 4th Street. It continues west until the Avenue of the Americas, where West 4th Street turns north and confusingly intersects with West 10th, 11th, 12th, and 13th Streets in Greenwich Village. Most of the street has the same 40-foot (12 m) width between curbstones as others in the prevailing street grid, striped as two curbside lanes and one traffic lane, with one-way traffic eastbound. The portion from Seventh to Eighth Avenues is westbound and is approximately 35 feet (11 m) wide, a legacy of the original Greenwich Village street grid. The section of four short blocks from MacDougal Street to University Place which forms the southern border of Washington Square Park is called Washington Square South.
