The Brooklyn Bridge looms majestically over New York City’s East River, linking the two boroughs of Manhattan and Brooklyn. Since 1883, its granite towers and steel cables have offered a safe and scenic passage to millions of commuters and tourists, trains and bicycles, pushcarts and cars. The bridge’s construction took 14 years, involved 600 workers and cost $15 million (more than $320 million in today’s dollars). At least two dozen people died in the process, including its original designer. Now more than 125 years old, this iconic feature of the New York City skyline still carries roughly 150,000 vehicles and pedestrians every day.

The Man with the Plan

John Augustus Roebling, the Brooklyn Bridge’s creator, was a great pioneer in the design of steel suspension bridges. Born in Germany in 1806, he studied industrial engineering in Berlin and at the age of 25 immigrated to western Pennsylvania, where he attempted, unsuccessfully, to make his living as a farmer. He later moved to the state capital in Harrisburg, where he found work as a civil engineer. He promoted the use of wire cable and established a successful wire-cable factory.

Did you know? On May 17, 1884, P. T. Barnum led 21 elephants over the Brooklyn Bridge to prove that it was stable.

Meanwhile, he earned a reputation as a designer of suspension bridges, which at the time were widely used but known to fail under strong winds or heavy loads. Roebling is credited with a major breakthrough in suspension-bridge technology: a web truss added to either side of the bridge roadway that greatly stabilized the structure. Using this model, Roebling successfully bridged the Niagara Gorge at Niagara Falls, New York, and the Ohio River in Cincinnati, Ohio
