Wikipedia: Fulton Street/Broadway–Nassau Street is a rapid transit station on the New York City Subway in Lower Manhattan, New York City, United States. It consists of four linked stations: Fulton Street on the IRT Lexington Avenue Line, the BMT Nassau Street Line, and the IRT Broadway–Seventh Avenue Line and Broadway–Nassau Street on the IND Eighth Avenue Line. The first three cross Fulton Street at Broadway, Nassau Street, and William Street respectively; the Eighth Avenue Line station is underneath Fulton Street, between Broadway and Nassau Streets. The station is the tenth busiest in the system as of 2008 with 19,813,040 passengers. The Fulton Street Transit Center is a project, currently in progress, that will improve access throughout the transfer station, introduce a new station building, and provide easier access to the World Trade Center site.
