Seventh Avenue originates in the West Village at Clarkson Street, where Varick Street becomes Seventh Avenue South (which becomes Seventh Avenue proper after the road crosses Greenwich Avenue and West 11th Street). A part of the avenue in the Garment District is co-named Fashion Avenue. It is interrupted by Central Park from 59th to 110th Street. Artisans' Gate is the 59th Street exit from Central Park to Seventh Avenue. North of Warriors' Gate at the north end of the Park, the avenue carries traffic in both directions through Harlem, where it is called Adam Clayton Powell Jr. Boulevard. Addresses continue as if the street was continuous through Central Park, with the first block north of the park being the 1800 block. The United States Postal Service delivers mail using either street name. As is the case with "Sixth Avenue" and "Avenue of the Americas", long-time New Yorkers continue to use the older name.
