Grand Central Terminal Station 100th Anniversary, New York City, United States

Near the north end of the passages, there is an Arts for Transit mosaic installation by Ellen Driscoll, an artist from Brooklyn.
The entrances to Grand Central North were originally open from 6:30 AM to 9:30 PM Monday through Friday and 9 AM to 9:30 PM on Saturday and Sunday. As of summer 2006, Grand Central North was closed on weekends, with the MTA citing low usage and the need to save money by the shutdown. Prior to the closing, about 6,000 people used Grand Central North on a typical weekend, and about 30,000 on weekdays.
Ideas for a northern entrance to Grand Central were discussed since at least the 1970s. Construction on Grand Central North lasted from 1994 to 1999 and cost $75 million. Delays were attributed to the incomplete nature of the original blueprints of Grand Central and previously undiscovered groundwater beneath East 45th Street. As of 2007, the passages are not air-conditioned.
