Suspension Bridge: The Golden Gate 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.

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

I feel that the Sundial Bridge is the most successful public sculpture we have in Redding. I feel that the bridge has a lot of mass with it being 700 feet long, 23 feet wide, 217 feet high, and weighing 3.2 million pounds, the Sundial Bridge it rated Redding's top attraction. It is also the first free-standing bridge in the United States.

Stretching across the San Francisco Bay stands the world famous Golden Gate Bridge. The bridge is located in one of nature’s most beautiful settings, spanning the mile-wide bay from Fort Point in San Francisco to the Marin County Shore. Joseph Strauss, specializing in bridge building, was the leader of the construction of the Golden Gate Bridge. The start of construction began on January 5, 1993 and, after four years, was completed on April 27, 1997. The bridge was needed to be built because of the growing population after the California Gold Rush. The bridge was a difficult task for engineers and is now an inspiration. The Golden Gate Bridge is one of the largest suspension bridges and is well known around the world. The Golden Gate

The French government had donated that bridge to help the Haitian people. As I stated before, this kind of bridge must not stay on the terrain for a long time. This time would be different due to the peculiar situation of those villages. The cities of Dondon and San Rafael used the former bridge for many purposes like to take children to school, go to the doctor appointments and day-by-day displacements. The old bridge had fallen three years ago during a tropical storm. Since that day, people used a ford path in the river to cross. They really needed that bridge.

The towers were built of granite and had two arches. These towers were taller than any other building in the city. The two towers held massive steel cables that spanned from one side of the bridge to the other. This design was used to keep traffic flowing and the roadways were designed to keep constant movement of traffic. The reason for the towers having to be that high was because ships had to be able to go under the bridge. None of this would have been possible if it wasn't to roeblings invention of the steel cable. To make the 4 main suspension cables wires were pulled strand by strand to be formed into one massive cable. Each cable was consisted of 6,289 of these wires. 331 wires to a strand and 19 strands to a cable. While the cables were being put on the bridge a huge problem had aroused. “The J.Lloyd Haigh” company that was responsible for giving the wire for the cables to hold the ends of the bridge up, the cables were found to be faulty wires. It was impossible at that time to redo the cables for the bridge, roebling told everyone who knew to keep the story as quiet as possible and 150 extra wires were added to each cable to strengthen them. The owner of the company “J.Lloyd Haigh” was put in jail for giving faulty wires. Spinning the cables between the towers began in the summer of 1877, and was finished a year and four months later. But it would take another five years to

Today the golden gate bridge still stands after 79 years. After learning all of this about the Golden gate bridge I feel that the Golden gate bridge is safer and it was made to hold thousands and thousands of pounds. The architects that designed the bridge designed it to withhold it makes me feel safer going back.

Once the construction began workers risked their lives every day facing the challenges of high winds, ocean currents, and fog. Eleven total workers died in the making of the bridge, ten people all in one day on February 17, 1937 when the scaffolding fell through the safety net. Other than the issues that had gotten in the way, the Golden Gate Bridge was completed in 4 years on May 27, 1937. Roughly about 200,000 people had come to celebrate the opening of the bridge. That following day, President Roosevelt signaled to the world that the bridge was open to traffic. The Golden Gate Bridge remained the longest bridge until 1964 when it was passed by sixty feet from the Verrazano-Bridge in New York City. (History

The Golden gate bridge and also it is a suspension bridge. The Golden Gate Bridge is one of the largest suspension bridges there are in the entire world. Also the Golden Gate Bridge also as to get painted every single year to make it look like the Golden Gate Bridge again. The Golden Gate Bridge was also located in San Francisco California. The Golden Gate Bridges

First, I would like to tell you about the Golden Gate Bridge. I’m pretty sure many of you may know about this bridge. The Golden Gate Bridge is a suspension bridge and was built in San Francisco, California in 1937. The Golden Gate Bridge spans or crosses the Golden Gate strait which is a mile wide and 3 miles long. The weight of the roadway is hung from 2 cables that pass through two main towers and are fixed in concrete at each end. Each cable is made of 27,572 strands of wire. There are 80,000 miles of wire in the main cables. These cables help support the bridge because of the big distance. The bridge also has approximately 1,200,000 total rivets. So my opinion about the bridge is that it is a very well made bridge and it also has a very good design.

With New Yorks skyscrapers it is hard to believe that the United States was not the leader of the construction of the first modern bridge in the world, according to Historic American Engineering Record(2008), the first modern bridge in the United States was built in 1 November 1855, and was named Gasconade Bridge, it was made out of Wooden Rail Bridge. Bridges are built all over the United States for different purposes but they are built to connect two parts of land together for transportation for instance, Hoover Dam Bridge, and others are built for commercial reasons and some are built for tourism for example, the Royal Gorge Bridge. But they have the same concept of connecting to lands together regardless to the reasons that they were constricted for. It

No design is perfect. The Oakland Bay Bridge consisted of two eight-mile long, suspension bridges. C. H. Purcell first built it in the 1930’s. According to Britannica Online, he originally had structural issues with the sinking to bedrock in the central anchorage. When repairing the bridge after Loma Prieta, the challenge was making it more seismically sound. The West Span of the bridge held up due to its suspension design. This led to the West Span being more flexible than the East. Bridges must have a certain level of flexibility, but not so flexible that extreme conditions would create another disaster such as the Tacoma Narrows Bridge Collapse of 1940. The West side of the bridge was mostly in tension when the earthquake hit. Allowing the bridge to absorb forces and create equal and opposite forces of its own kept the West side of the bridge intact. However, the stiffness of the East Span of the bridge was too stiff to handle the brute force of the Loma Prieta earthquake. Having flexibility in a design allows for the bridge to react to outside forces. Being too rigid would give necessary allowance for certain

To begin with, The Golden Gate Bridge is one of many attractions in San Francisco. The bridge was built in 1937 by Joseph Strauss and Charles Ellis. The bridge stretches 8,981 feet with a height 746 feet. The bridge is one of the best sights to see in America. And to finish off, the bridge is just about unbreakable.

Along with bridge design, he also created a plan for the Lincoln Tunnel construction. He also opened New York and heaviest suspension bridge of the world in New York. That bridge named as Verrazano-Narrows Bridge also has the 8th position among the longest span on the globe. His contribution to the building of Golden Gate Bridge enabled it to rank at 9th placed among the best buildings in the

On the 15th of December, the bridge collapsed during a busy rush hour and a total of 46 people were killed, 2 of which were never found. After much analysis of the wreckage it was found the collapse had been due to a few factors. Whilst the busy traffic had meant that the bridge was carrying loads far greater than had been originally foreseen during the design, the bridge had also been very poorly maintained in the time leading up to the collapse. The main cause of the disaster was due to the failure of an eyebar. A small defect in the bar was found that was a mere 2.5mm, but due to the specific eye bar construction used, this defect lead to the total failure of the Bridge.
