How long was the Brooklyn Bridge built to last?
The Brooklyn Bridge took 14 years to build, starting in 1869 and ending in 1883. Roebling, a German immigrant, was named Chief Architect in the initial planning. The bridge looks the way it does today because of his original designs, which took three months to put together.
How were the foundations of the Brooklyn Bridge built?
To construct foundations for the bridge towers, engineers sank a pair of watertight wood-and-steel chambers, called caissons, face down into the East River.
When did they finish building the Brooklyn Bridge?
1883
The Brooklyn Bridge, Roebling’s last and greatest achievement, spans New York’s East River to connect Manhattan with Brooklyn. When completed in 1883, the bridge, with its massive stone towers and a main span of 1,595.5 feet between them, was by far the longest suspension bridge in the world.
How did caissons work?
Workers, called sandhogs, move mud and rock debris (called muck) from the edge of the workspace to a water-filled pit, connected by a tube (called the muck tube) to the surface. When the caisson hits bedrock, the sandhogs exit through the airlock and fill the box with concrete, forming a solid foundation pier.
Who constructed the Brooklyn Bridge?

Why was the Brooklyn Bridge necessary?
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.
Why did John A Roebling build the Brooklyn Bridge?
Their ambitious project was a suspension bridge across the East River to connect Manhattan and Brooklyn. Roebling’s design had to address several challenges. The bridge had to be long enough to connect Brooklyn and Manhattan and high enough to allow tall ships to pass under it.
Did a woman design the Brooklyn Bridge?

What was the construction of the Brooklyn Bridge?
Written By: Brooklyn Bridge, suspension bridge spanning the East River from Brooklyn to Manhattan in New York City. A brilliant feat of 19th-century engineering, the Brooklyn Bridge was the first bridge to use steel for cable wire, and during its construction explosives were used inside a pneumatic caisson for the first time.
How big was the caisson used for the Brooklyn Bridge?
One of the first things Roebling did was design and have built two giant caissons, which were 17,000-square-foot airtight wooden boxes without a bottom. Caissons had been used before but never at this scale.
How did workers die on the Brooklyn Bridge?
The surgeon had him taken to the hospital.” As the caisson on the New York side descended deeper under the water, more workers became sick and three died of the bends. Roebling himself often went into the caissons to supervise the excavation. He was struck several times with decompression sickness.
