Brooklyn Bridge

It is 1933. Construction begins. 1937, this landmark is completed and opened to pedestrians and vehicles. It is built at a cost of approximately $35.5 million and comes in under budget and ahead of schedule. World War I veteran Harold Wobber, this landmarks first suicide, claimed, "This is where I get off,” and then jumps to his death. Now jump to 2013. Nearly 1,600 people have committed suicide by jumping off. The average number of suicides from this landmark is three per month. The Golden Gate Bridge was an example of a feat of engineering.

were very poor, but somehow, many architectural feats were being made. The U.S. Government was still building the greatest dam in the world before the Depression, the Hoover Dam, which lasted five years to build. It takes a lot of manpower and materials for the Government to build this great dam, so they hired contractors to build it and the The U.S. provides the materials. Men of six companies were hired to build the dam in 7 years or penalties will ensue; the men were called, Six Companies, Inc. Remarkably, the contractors banded together to build the dam because of the immense size of the structure, one contractor cannot do the task alone (America's Experiences). The Dams magnificent feat in becoming USA’s greatest dam inspired the same contracting firm to work on a certain bridge in the west (Hiktzik). During the time Hoover Dam was being constructed, out in the west, another architectural feat was occurring. In 1933 San Francisco, California, construction starts on what will soon to be one of America’s greatest landmarks, The Golden Gate Bridge. One of the bridges architects, Joseph B. Strauss, a man who built many bridges across the U.S., was involved in the bridge project. Strauss and his colleagues had to deal with many problems about the bridge such as people saying it had to be impossible or it was expensive and a hazard to the environment (History.com). Once the bridge was funded with thirty-five million dollars,

When bridges are poorly constructed, they may fail due to load they carry, collision by derailed trains or even by vehicles that lose control leading to catastrophic incidences. However, if bridges are well-constructed, the chances or injury are greatly minimized in the event of an accident. Discussed in the subsections are the requirements of AS 5100 standards in relation to cable-stayed bridges and include design requirements for bridges, bridge aesthetics, bridge functional requirements, bridge component design requirements and bridge construction

The first completed steel bridge was the Eads Bridge, in St. Louis Missouri. Steel was a very new material and was just starting to become commercially available. Steel was a smart choice to use because it is extremely hard and resists rusting. The Eads Bridge was the longest arch bridge in the world, of 510 feet long. St. Louis became a very important city in the midwest and had to really compete with Chicago during the Civil War. After the Civil War, St. Louis started growing in all directions. “.... the city of St. Louis wanted to reestablish its prewar dominance as the economic powerhouse of the midwest” (Ostrow 75). The main reason to build the Eads Bridge was to connect settlers from the East to the lands of the West. At the time there

Albany's welcome center began its life as a bridge house. Nelson Tift, the founder of Albany, commissioned construction of the house along with a new bridge. The new bridge, built in 1858, was to serve as a gateway to the city along with providing extra revenue from tolls collected at the house. At Tift's request, an African-American slave and architect oversaw completion of the project. His name was Horace King.

Thomas Paine helped build the Sunderland bridge in England. He was a director of one part of the bridge. He managed some of the building materials. The bridge was built over the River Wear. Some of the arches were rebuilt in 1770.

In the small town of Waco, Texas who would have thought it was once well known for the structure of a bridge, the Waco Suspension Bridge to be exact. Up until 1870, the Brazos River was just a simple river that had no special meaning to it. The land around it was empty, occasionally you would find cattlemen pushing their cattle across stream, but that was only because you could not find one bridge that spanned the eight hundred miles of river flowing through Central Texas. This caused a serious transportation issue for merchants and travelers. It became clear that a better means of crossing the river was necessary.

In the middle of nowhere, in that vast expanse of trees, lies The Bridge. Nobody knows it as any other name. It stretches across the Dead River, just sitting there waiting for someone new to find it. At one time it was driven over constantly, a way of travel for the inhabitants who are crazy enough to live out there. But now it is just there, a giant chunk of metal, rusting away into nothing. Occasionally it is used for things like fishing, or as a

Number Seven: Brooklyn Bridge.The Brooklyn Bridge is a suspension bridge spanning the East River from Brooklyn to Manhattan Island. It has become an icon of New York City and a National Historic Landmark.

In the late 19th century, the transportation demands of Quebec and other provinces success in transportation like Montreal’s success in railways led to proposals for bridging the St. Lawrence River. Quebec Bridge has a long story behind it, a bridge that was proposed first back in 1852 but it was not complete until 1919. It collapsed two times in this duration once in 1907 killing 75 workers and second time in 1916 killing 13 workers. In this report I will emphasize on the first collapse.

Suspension bridges were important before 1940 and are still important today. Major cities such as San Francisco, and Manhattan both have a suspension bridge. Suspension bridges are,” a bridge having a deck suspended from cables anchored at their extremities and usually raised on towers” (dictionary.com). Due to the fact that suspension bridges are not completely supported throughout the length of the bridge, past bridges were unsafe. For example, the Tacoma Narrows Bridge was a suspension bridge opened on July 1st, 1940 (Mark Ketchum). This bridge marked a huge point in suspension bridge safety and engineering, because in collapsed approximately four months after it was opened (Parsons). The collapse caused such a shock, that suspension

In 1919, a study was begun to see if it would be possible to build a bridge across the Golden Gate. Michael O’Shaughnessy was the San Francisco city engineer. He was in charge of the rebuilding of the city after the devastating 1906 earthquake that destroyed much of the city. O’Shaughnessy knew the need for the city to have bridges. Most said it could not be done and others said it could be done but “it would cost about $100 million to build it” (Barter 23). O’Shaughnessy and Strauss, both wanting the same thing, got together. After the two consulted, they figured the only way to bridge the channel was to use a suspension bridge.

In the past construction also took less time. One reason for this is that safety regulations were not nearly as strict then as they are now. It was understood 80 years ago that any major construction project would come with the loss of life. According to Lisa Vorderbrueggen from Contra Costa Times, for every $1 million to be spent on a project regarding high steel work, there would be one death. In total the bridge cost was $77 million (equivalent to about $1.3 billion in current dollars) and resulted in 24 deaths (Vorderbrueggen).

The Tacoma Narrows Bridge is perhaps the most notorious failure in the world of engineering. It collapsed on November 7, 1940 just months after its opening on July 1, 1940. It was designed by Leon Moisseiff and at its time it was the third largest suspension bridge in the world with a center span of over half a mile long. The bridge was very narrow and sleek giving it a look of grace, but this design made it very flexible in the wind. Nicknamed the "Galloping Gertie," because of its undulating behavior, the Tacoma Narrows Bridge drew the attention of motorists seeking a cheap thrill. Drivers felt that they were driving on a roller coaster, as they would disappear from sight in the trough of

A bridge is a structure providing path over an obstacle. When constructing a bridge, obstacle can be a river, railway track or a valley and the path provided by bridge can be for a road, pedestrians, a railway, pipelines, viaducts to carry water from rich areas to dry cities, or for commercial purpose to host commercial buildings such as restaurants and shops. A bridge can also be laid to reduce the distance of travel which in turn reduces the time to reach the destination.
