qz.com reports that sitting below one of the most famous parks in the world is a half-mile train tunnel built by the city of New York forty years ago that you won’t find on any subway map. Sometimes it’s there, and sometimes, it’s not. This tunnel has sat below Central Park, barely used, for decades. Thanks to the first major piece of work done to New York’s subway system since the 1980s, commuters will soon be able to ride in this previously hidden subway structure.
The tunnel, which runs between the 57th Street and 7th Avenue, and Lexington Avenue and 63rd Street in Manhattan, has never had a dedicated train line running through it. If you’re heading northbound on an N, Q, or R train from 57th Street, for a second, you’ll get a glimpse of it, but according to archivists for the Metropolitan Transportation Authority (MTA), New York’s governing body of public transit, it’s only appeared on subway maps for two brief periods in 1995 and 1998.
Assuming everything goes according to plan, commuters in New York City will soon be traveling through the piece of tunnel below Central Park. The MTA is in the process of completing the Second Avenue line, nearly a century after it was first proposed. To read the article in its entirety, along with seeing photos, click here.
