Where is the northwest passage in Grand Central Station?

Answer 1

The Northwest Passage for Grand Central North, opened on August 18, 1999, provides access to Grand Central from 47th Street and 48th Street. It is connected to the Main Concourse through two long hallways, the Northwest Passage (1,000 feet long) and Northeast Passage (1,200 feet long), which run parallel to the tracks on the upper level.

Entrances are at the northeast corner of East 47th Street and Madison Avenue (Northwest Passage), northeast corner of East 48th Street and Park Avenue (Northeast Passage) and on the east and west sides of 230 Park Avenue (Helmsley Building).

The 47th Street passage provides access to the upper level tracks and the 45th Street passage provides access to the lower level tracks. Elevator access is available to the 47th Street (upper level) passage from street level on the north side of E. 47th Street, between Madison and Vanderbilt Avenues. (Note there is NO elevator access to the actual train platforms from Grand Central North, handicapped access is provided through the main terminal).
