The Golden Gate Bridge is a major tourist attraction in San Francisco, California. It is one of the longest suspension bridges in the world. It’s also the top suicide location in the world.The Golden Gate Bridge is a symbol of Northern California. The bridge serves as a means of transportation. The Golden Gate Bridge is located across the San Francisco Bay in San Francisco, California. Construction began January 5, 1933, and the bridge opened to the public May 28, 1937. The bridge connects the city of San Francisco's northern tip of the San Francisco Peninsula to Marin County, California. It took approximately 4 years to construct The Golden Gate. The bridge was built so they wouldn't have to use ferries to cross over the water. The bridge still exists today. The bridge has approximately 120,000 visitors each day. The Golden Gate Bridge is a suspension bridge, one of the longest in the world. A suspension …show more content…
In her essay,”Importance of the Golden Gate Bridge,” Stephanie Stiavetti suggest that “It maintained this point of pride for nearly 25 years until the Verrazano- Narrows Bridge was built in New York in 1964. Today, this historic San Francisco landmark holds its place as the second largest suspension bridge in the country, behind Verrazano Narrows.” Back then, experts thought that it would be impossible to build a bridge across the tides and currents in that area because strong currents and tides would make construction extremely difficult and dangerous. The water is over 500 feet deep in the center of the channel, and along with the area's strong winds and thick fog, the idea of building a bridge there seemed nearly impossible. Despite all of the problems of building the bridge, Joseph Strauss was named as lead engineer for the project. Construction began January 5, 1933, and in the end cost more than $35 million to
At the time of its construction in 1929, the Ambassador Bridge was the largest spanned suspension bridge at 564 meters until the George Washington Bridge was built. It was an engineering masterpiece at the time. The total bridge length is 2,286 meters and rises to 118 meters above the river. Suspension cables support the main span of the Ambassador Bridge and the main pillars under the bridge are supported by steel in a cantilever truss structure. In total, the McClintic-Marshall masterpiece is comprised of 21,000 tons of steel. The immense socio-economical impact that the Ambassador Bridge has on transportation and trade is imperative for daily interaction between the Un...
According to Suspension bridges: Concepts and various innovative techniques of structural evaluation, “During the past 200 years, suspension bridges have been at the forefront in all aspects of structural engineering” (“Suspension”). This statement shows that suspension bridges have been used for over 200 years, and that people are still using them today because they are structurally better bridges. This paper shows four arguments on the advantages of suspension bridges, and why you should use one when building a bridge. When deciding on building a suspension bridge, it has many advantages such as; its lightness, ability to span over a long distance, easy construction, cost effective, easy to maintain, less risk
The 1906 San Francisco earthquake was one of the largest earthquakes in the United States. Even though it only lasted less than a minute, the damages and aftermath of the earthquake were disastrous. These damages were not just from the earthquake, but also from other hazards that occurred because of it. It also had a huge effect on the people living in San Francisco. Many people, the government, and other countries helped the city of San Francisco with relief goods like food and clothing. The city used up their resources in order to rebuild the city and spent a lot of money. This earthquake also started a scientific revolution about earthquakes and its effects.
The San Francisco Earthquake commenced at five thirteen o’clock in the morning, with the epicenter offshore of San Francisco. The city carried more than 400,000 people during this event (Earthquake of 1906, 1). Most of the
The San Francisco earthquake that took place in 1906 is fairly well-known because of its damage and intensity that would affect many lives. The online exhibit of The 1906 San Francisco Earthquake and Fire shows how much was lost during this natural disaster, and how the city was before. Many would wonder what is the purpose of documenting how it was before, and after the earthquake, but the fact that no one was expecting one so big impacted countless lives. Also, at the time San Francisco was becoming the most popular city, therefore it would appear in the headlines how a well-known place that most people loved would become damaged (The Bancroft Library, 2006). Overall, this virtual field trip shows the cause and effect of the earthquake that would change San Francisco in numerous ways.
In the early twentieth century, San Francisco, a bustling city full of people from diverse cultures, stood in the midst of the Second Industrial Revolution. At this time, the brilliant inventions of airplanes, automobiles, and radios were changing the everyday lives of many. San Francisco had just recovered from the four-year burden of the bubonic plague (“Bubonic”). However, right when things were going back to normal, a destructive earthquake hit the city on April 18, 1906. Although the shaking lasted for less than a minute, the devastated city had crumbled buildings and a substantial loss of lives. The San Francisco earthquake of 1906 consisted not only of earthquakes, but also of even more destructive fires; it had a scarring effect on the city and its people, yet it gave much of the knowledge that seismologists have today and allowed San Francisco to stand as a place of intriguing buildings and structures.
The 14-year construction of this urban landmark that stretched across the East River was completed in May of 1883. This was not only a bridge; it stood for many significant symbols. During this time period, the industrial aspects of things were at its peak and this represented the strength of the industry. Also it symbolized the use of immigrant workers and how much time and effort they put into making this bridge. Twenty seven men died while creating this bridge and that is something that most people forget when looking at the bridge, people risked there lives while giving a society that people needed. Not only that but it took tons and tons of steel and iron in order to complete this bridge and it was part of the steel and iron boom. This landmark led to the rise o...
This all iron design made the bridge a lot heavier than it was designed for, which added more stress to the truss. This fact, by itself, wouldn’t cause any alarm. However, the bridge itself, was very poorly constructed. The members of the bridge were all different sizes, and they were not connected together properly. Due to the poor construction and eleven years of use, members of the bridge had started to bend due to the stress. Despite bridge engineers inspecting the bridge for eleven years, no one noticed these faults with the bridge. However, the ultimate cause of this collapse, was so tiny, only one of the investigators, after the collapse, noticed it. A tiny air hole was left during the construction of the bridge, “and grew with repeated stress over eleven years” (Escher, 2009). This hole would develop in a crack, due to the changing temperatures and the trains crossing it for over eleven years. This would weaken the overall strength of the bridge. The cold winter air and the weight of the train would ultimately prove to be too much, and the whole bridge came crashing
The first and most challenging problem associated with building the Mackinac Bridge arrived long before the bridge was even designed. Financing such an enormous project was no easy feat. In 1928, the idea of connecting the upper and lower peninsulas was proposed to Congress for the first time (Brown 4). At the time, the suspected bridge project was very much under government scrutiny and control. In fact, the initial boost in interest in pursuing the construction of a bridge came about due to the depression. The Public Works Administration (PWA) had been created under President Franklin D. Roosevelt’s New Deal economic plan which would fund certain construction projects with th...
Among the great peaceful endeavors of mankind that have contributed significantly to progress in the world, the construction of the Canal stands as an awe-inspiring achievement. The idea of a path between North and South America is older than their names.
On the night of April 18, 1906, the whole town was woken by erratic shaking. Although the earthquake lasted under a measly minute, it caused significant damage. Many fires started all throughout the city; San Francisco burned in turmoil.
At 5:12 a.m. on April 18, 1906, the people of San Francisco were awakened by an earthquake that would devastate the city. The earthquake was caused by a rupture of the northernmost 296 miles of the San Andreas Fault, leaving 225,000 homeless, 3,000 dead and 500 city blocks gone.
San Francisco is one of the most modern and accepting culture there is in the world. San Francisco has largely become what it is due to the past historical events that shaped this culture to the way it is, as well as the kind of people these events brought into this city. In a way, the series of events that unfolded seemed to work almost too perfectly, and turned San Francisco into the city it is today.
In 1872, Charles Crocker, a railroad entrepreneur, called for a bridge that connected the Golden Gate Strait. The strait, approximately 3 miles long and 1 mile wide, is the entrance to San Francisco Bay, which is in California, from the Pacific Ocean. By 1916, Michael M. O'Shaughnessy, a San Francisco City Engineer, was asked by city officials to see if it was possible to build a bridge that crossed the strait. While most engineers claimed that a bridge was not able to be built and that it would cost about $100 million, Joseph Baermann Strauss claimed that a bridge would be easily built and would only cost about $25 to $30 million. After the long process of having the bridge design approved for constructing, on January 5, 1933, the construction of the Golden Gate Bridge had begun (“Golden Gate Bridge Research Library”). The main constructors included Joseph Baermann Strauss, Irving Morrow and Charles Ellis. Strauss had hired Irving Morrow to design small features for the bridge like pedestrian walkways and streetlamps. Morrow also made the bridge look luxurious by using a style called art deco (“Irving Morrow” and “Art Deco”). Since Morrow was to design the Bridge, he knew that it would play a significant role on its display in regards to its surroundings. As of today, “the color blends perfectly with the changing season tints of the spans’ natural setting against the San Francisco skyline and the Marin hills” (“Golden Gate Bridge Research Library”). Meanwhile, Charles Ellis was the engineering expert. He was later accused by Strauss of wasting money and time by working on equations of forces at the Golden Gate Bridge. Ellis was then told not to go back to construct the bridge. Ellis could not drop out of the project because he w...
The Golden Gate Bridge is “considered to be one of the best and most beautiful examples of bridge design” (Poel and Royakkers 110). Unfortunately, this bridge is also "the US's most popular place to commit suicide" (110). Due to this fact, bridge designers decided that they needed to consider the option of installing some sort of suicide prevention system. Before any decision was made, the ramifications of both implementing a system and not implementing one had to be considered. Deciding whether or not to implement a system calls for an in-depth analysis of the ethics. One must identify the ethical dilemmas present, and provide analysis on the effects on all the stakeholders involved.
