How the Men Who Built the New York City Subway Drilled Through Manhattan Bedrock Without Maps

12,000 men drilled through Manhattan bedrock without maps, without machines, and without anyone writing their names down. This is the story they left out of the history books. In 1900, New York City was seizing up. Two million people packed onto a 13-mile island with no way through it. The elevated railways were full. The streets were gridlocked. The only solution was to go underground — through solid granite and schist, past gas mains nobody had mapped, under the foundations of a thousand buildings that could not be allowed to move. What followed was four years and seven months of drilling, blasting, and dying in the dark for a dollar seventy-five a day. The men who did it were Irish, Italian, Sicilian, and Polish. They came through Ellis Island and went straight underground. The subway they built still runs today. Their names did not make it onto a single tile.
