One hundred forty-four thousand vehicles cross the bridge every day. Even at five cents, they could be making some money. (http://www.pbs.org/wgbh/buildingbig/wonder/structure/brooklyn.html. October 25, 2002).
This paper will give a feel for why this bridge is such a landmark in civil engineering. Lots of questions need to be answered. When and why was this bridge built? How did they build it? Why is so much myth and fascination surrounding the Great Bridge? This paper will try to cover all these topics.
WHEN AND WHY TO BUILD .
The decision to build the bridge was made a certain point in history and with specific reasons.
When.
The thought didn't just spring out all at once. Plans for a crossing between the city of Brooklyn and lower Manhattan dated way back to the early 1800's. At the point when the East River crossing was planned, Brooklyn was just shy of half a million people. Seems fairly large, but it was still a rural location in a lot of aspects. The city of New York was only Manhattan. No other boroughs sat under its name. New York still had twice as many people as Brooklyn and the bridge was seen as a solution to overcrowding in Manhattan. It would also jump start some needed development in Brooklyn. It seemed obvious that the bridge would allow the citizens along with goods to cross the East River quickly. Weather would no longer have to be as big an issue. .
Roebling.
So what next? In 1855, John Roebling proposed a suspension bridge over the East River. Roebling was the owner of a wire-rope company and known for his bridge designs. He had become impatient with the Atlantic Avenue-Fulton Street Ferry. That was the only way across at the time, and it had many hassles. John Roebling worked out every detail of the bridge personally. The massive towers and the four steel cables that would be used came from his brain. The elder Roebling had a lot of experience with suspension bridges on rivers in the region between 1848 and 1867.

He did the Niagra River Bridge in 1855, the Cincinnati bridge in 1866, and his last project was the Brooklyn Bridge in New York City. ... He did die before the bridge was finished, but his son finished the bridge before Eiffel finished...
Expansion The replacement bridge was expanded from the original bridge according to the "South Dakota Bridge System Code Manual - 1998 Edition- obtained from the SDDOT. The replacement bridge was then extended to span 120 ft. as compared to the original length of 90 ft. All design of the bridge girders and deck is based on the 120 ft expansion. ... Bridge Type The design of this structure is for a continuous span, prestressed concrete I-Beam girder bridge with a continuous reinforced concrete deck and a New Jersey barrier. ... The width of the bridge is 38 ft from outside edge to o...
The place I chose to go was to the Natural Bridges State Beach in Santa Cruz. ... The bridge connected by three arches that were carved out of sandstone cliff is what inspired the naming of the Natural Bridges. Waves" crashing into the walls of the cliffs is what created the bridge as well as other natural bridges. As time goes on, the bridges are slowly starting to erode and fade away. ... The Ohlone Indians were the first people to inhabit the Natural Bridges area. ...
History of Bridges History of Bridges Although bridges often go unnoticed, their function is essential to modern America. ... These rope bridges were the fore- runners of modern suspension bridges. ... This bridge is a combination of the arch, truss, and suspension bridges. ... Cantilever bridges are a type of truss bridge. ... This type of bridge is used extensively for railroad bridges. ...
These new rail bridges had to low, flat and strong. ... Anthony Bonzano of the bridge company told General Kane that they would "build you a bridge a thousand feet high if you'll provide the money."" ... The second bridge I will talk about is the Forth Railway Bridge, across Scotland's Firth of Forth. ... In 1806 the idea of building a bridge was put forward. ... The problem here was that most bridges that spanned this distance were suspension bridges, but it was obvious that in this case a suspension bridge would not be adequate. ...

Bridges have come a long way since their early history. ... As a result, protection was added to the bridges.
