Transcript of The Brooklyn Bridge

The Brooklyn Bridge
Why was the Brooklyn Bridge so important?
The only method of transportation from Brooklyn to New York was the ferry.
The Ferry system wasn't the best method of transportation because they were always filled with workers.
Did the Brooklyn Bridge bring a positive or negetive impact?
The construction of the Brooklyn Bridge had a positive impact on the economics of New York City
The construction of the bridge also enabled easier transportation from Brooklyn to New York

Opening Day
On May 24th, 1883 the Brooklyn Bridge opened. Emily Roebling was given the first ride across the bridge and in 24-hours there were an estimated 250,000 people walked across the bridge.
How exactly was the bridge built?
Who designed this beautiful bridge?
John Roebling
John Augustus Roebling was a german immigrant who moved to the United States in 1831. Prior to the designing of the Brooklyn Bridge he invented the steel cable and he soon realized how practical they were. After designing and helping build Allegheny Suspension Bridge, and the Niagara Falls Suspension Bridge he designed the Brooklyn Bridge.
Washington Roebling
After the death of his father, Washington became the man in charge of the bridge construction. He was moving the project along at a good pace until he fell ill with "the bends," this left him incredibly ill and never fully being able to recover.
Sadly, while surveying the east river John's foot got crushed between the ferry and the dock. And after two weeks John A. Roebling died of Tetanus, leaving his son Washington Roebling in charge of the building of the bridge.
Emily Roebling
Emily Roebling was the wife of Washington Roebling. They met due to the fact that Emily's brother was the general of Washington during the Civil War. After Washington got "the bends" Emily became an errand girl and brought info to and from Trenton (where Washington was now residing).

It also enabled workers from Brooklyn to access the factories in New York City quicker and in a greater volume
Also when the weather was bad the ferry times toke longer and on snowy days the times stopped altogether.
When John A. Roebling designed the bridge he split the building into three parts.
Step 1: Caissons
The first part of the building was to sink large wooden crates called caissons. The purpose of the caissons was to create a stable base for the two stone towers that would suspend the bridge. First, they built the caissons on land. Then they would boat the caissons to their set locations. Finally, workers would mine until the caisson reached the bedrock on the East River.
Within the caissons a lot of problems occurred. The Brooklyn Caisson experienced rock slides and fires. As for the New York Caisson experienced never ending sand.
Also, with the workers going from compressed air to uncompressed air quickly and many times during the day medical emergency arouse.
The Bends
The Bends was a medical condition that usually affects Deep-Sea Divers. The Bends is caused by an imbalance of Nitrogen in the blood by the rapid changing of compressed air to uncompressed air.
Step 2: The Towers
Step two was to create the two 276 foot granite towers. John A. Roebling designed the towers with pointed arches to giving the bridge a Neo-Gothic theme.
Step 3: Cabling
Thanks to John A. Roebling's invention of the steels cables the final part of the bridge could be completed. Coiling the wires together, the workers made the cables that would support the road/walkway of the bridge
The whole building of the Brooklyn Bridge toke 14 years to complete and toke the lives of 12 workers including the original designer. There were many points that finishing the bridge seemed impossible, but someone the Roeblings got through it.

Problems (2)
The article linked is a newspaper article on a fire that occurred in chamber 2 of the Brooklyn Caisson. The article continues to say how the fire started and what the workers had to do to put the fire out.
The Workers
The workers in the caissons were usually European Immigrants. These immigrants made around $2 a day.
Not only that, but Emily also toke the role of Washington and made her own decisions in building the bridge.
