The Empire State Building: How New York Defied Gravity in 410 Days
In 1930, New York raced to build the world's tallest skyscraper during the Great Depression — 57,000 tons of steel, 3.4 million rivets, and 3,400 fearless workers assembled it all in just 410 days.
In 1930, at the height of the Great Depression, New York City built the world's tallest skyscraper in just 410 days — faster than most cities approve a permit today.
The Race to the Sky
Three towers competed for the title of world's tallest. The Empire State Building would crush them all. The old Waldorf-Astoria hotel was demolished in weeks to clear the site, and on March 17, 1930, steel columns began rising at an astonishing pace: four and a half floors per week.
Engineering at Speed
A steel beam left Pittsburgh and was riveted into place eighty floors up — all within 80 hours. Eleven custom derrick cranes leapfrogged upward as the tower grew, keeping pace with the relentless schedule.
The Workers
Every morning, 3,400 workers climbed the naked steel frame — no harnesses, no safety nets. Among them: Mohawk ironworkers from Kahnawake, Quebec, who balanced barefoot on beams high above the Manhattan clouds.
The Numbers
- 57,000 tons of steel
- 3.4 million rivets
- 700 million pounds of material
- Assembled in just 14 months
The Finish Line
On May 1, 1931, President Hoover pressed a button in Washington, D.C. — and the Empire State Building's lights blazed over Manhattan. It stood as king of the skyline for 40 years.
