Park Avenue is a boulevard in New York City[5] that carries north and southbound traffic in the boroughs of Manhattan and the Bronx. For most of the road's length in Manhattan, it runs parallel to Madison Avenue to the west and Lexington Avenue to the east. Park Avenue's entire length was formerly called Fourth Avenue; the title still applies to the section between Cooper Square and 14th Street.[6] The avenue is called Union Square East between 14th and 17th Streets, and Park Avenue South between 17th and 32nd Streets.
