THE OVERLOOKED WAYFINDING SIGNS AT GRAND CENTRAL MADISON
Can you see the teal “48” on the floor in the picture below? This subtle and often overlooked sign is part of a color-coded wayfinding system in Grand Central Madison that applies to the whole station. On our upcoming tour of the art in Grand Central Madison, you can locate these signs, uncover hidden works of art in the historic train terminal, and learn about the inspiration behind new pieces by famous artists such as Kiki Sith and Yayoi Kusama!
The concourse of Grand Central Madison, deep below the historic train terminal, stretches from 48th Street to 43rd Street. To help commuters navigate this massive space, a color-coded system was devised to mark each cross-street. Each street from 48th to 45th Street has its own artwork and a signature color. 48th Street is teal, 47th is purple, 46th is dark blue, and 45th is green.
