New York City’s first official subway system opened in Manhattan on October 27, 1904. The Interborough Rapid Transit Company (IRT) operated the 9.1-mile long subway line that consisted of 28 stations from City Hall to 145th Street and Broadway.

How long did it take to build the NYC subway system?

Iconic bridges, opulent railway terminals, and much of what was then the world’s largest underground and rapid transit network were constructed in just 20 years. Indeed, that subway system grew from a single line in 1904 to a network hundreds of miles long by the 1920s.

How did they build the subway underwater?

Does NYC subway flood?

A $40 million system can keep the subways from flooding—but in only one type of flood. After Hurricane Sandy devastated New York and flooded its subway system in 2012, the Metropolitan Transportation Authority (MTA) knew it needed to act.
