The Golden Gate Bridge is a major tourist attraction in San Francisco, California. It is one of the longest suspension bridges in the world and 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.

longest in the world. A suspension bridge is a bridge that hangs from cables that are made of tiny steel wires. Most bridges nowadays use a box section roadway supported by high tensile stress cables.A steel wire 0.1 inch thick can support up to half a ton without breaking. Therefore, the 80,000 miles of wire on the golden gate bridge can support many of tons. Light and strong suspension bridges can span distances from 2,000 to 7,000 feet longer than any other kind of bridge. A suspension bridge suspends the roadway from huge main cables, that extend to the other side of the bridge. Theses cables rest on top of towers and have to be securely anchored into the bank at both ends of the bridge. Compression and tension are the two forces that act on suspension bridges. Compression stress is the stress on materials that leads to a smaller volume. Tension stress is the state of being stretched tightly. Compression and tension work together to hold up some of the world's longest spans.These forces can work together by canceling each other out where a section of the bridge is compressed and where another force from another direction can make the member stretch back. The Golden Gate Bridge is 3 miles long and 1 mile wide. With six lanes of US 101 and California State Route 1. The Golden Gate Bridge is maintained by Golden Gate Bridge Highway and Transportation District. The highest point on the bridge is 746 feet high. The designers of the bridge are Joseph Strauss, Irving Morrow, and Charles Ellis. The Gold Gate Bridge was marked as a historical landmark on June 18, 1987. The Golden Gate Bridge became the San Francisco designated landmark on May 21, 1999. At the time of its construction in the 1930s, the Golden Gate Bridge was the longest suspension bridge in the world.
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 a bridge across the Golden Gate, 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
build. California's unpleasant San Andreas Fault passes through the north to the south of the Bay area, passing the Golden Gate a short distance out to sea. Charles Ellis sounded a confident note in a 1929 lecture to the National Academy of Sciences: "If I knew that there was to be an earthquake in San Francisco tomorrow and I couldn't get into an airplane and had to remain in the city, I think I should get a piece of clothesline about 1,000 or 2,000 feet long, and a hammock, and I would string it from the tops of two of the tallest redwoods I could find, get into the hammock and feel reasonably safe. If this bridge were built at that time, I would tie me to the center of it, and while watching the sun sink into China across the Pacific, I would feel content with the thought that in case of an earthquake, I had chosen the safest spot in which to be." For the men who did construction, it was a life changing experience. In her essay,”Life on The Gate: Working on the Golden Gate Bridge 1933-37,” Amy Standen states that “It was the middle of the Great Depression, getting a job on the Golden Gate Bridge was like winning the lottery.The conditions, above and below the water, were ‘atrocious’. Divers faced powerful currents as they helped anchor the massive concrete bridge support onto the ocean floor and up on the towers, workers stuffed newspapers in their jackets to keep warm.”

Ruby Bridges is a girl known for her courageous actions. Ruby went to a school that would discriminate colored people in the 1960s. She was the first African American to go to an all white school. Ruby Bridges was an American activist who became a symbol of the civil rights movement. An activist is someone who campaigns to bring about political or social change.
...iewing of the Mackinac Bridge. It is now known by Michigan residents as the “Mighty Mac.” Over the years, the Mighty Mac has seen several iconic moments in history including a wedding proposal in the emergency lane and the sudden birth of a child halfway across the bridge. With each new story, the Mackinac Bridge becomes further steeped in Michigan history and an even greater symbol of the Great Lakes State. The bridge is now a common event location. The annual “bridge walk” attracts over 50,000 participants every Labor Day weekend, but other groups have arranged various crossings. Everything from Harley Davidson Motorcycle rallies to organized Chevrolet Corvette crossings has taken place on the Mighty Mac, as well as a plethora of bicyclist groups. The Mackinac Bridge provides a thrilling passage between the peninsulas and has become the portrait of Michigan.
In 1939, the city of San Francisco hosted an international exhibition, named the Golden Gate Fair in honor of the construction by the city of the world's two largest suspension bridges, the Golden Gate and San Francisco-Oakland, which spanned the San Francisco Bay. With all the skill that could be mustered by American engineers, an island was constructed amidst the Pacific waters, becoming the largest ever manmade island. Christened Treasure Island, this would be the location of the 1939 Exhibition. The visions of a fair surrounded by the glory of the Pacific Ocean had finally materialized. However, this captivating scene took place as Europe verged on the edge of disaster. Germany had already begun its annexation of neighboring countries and threatened to unleash conflict on a global level. In only two short years the United States would be fully involved in this catastrophe. Furthermore, at the time of the fair the United States had just emerged from the Great Depression, which had affected the country in many ways. This fair seemed to provide a brief interlude between these two very difficult times in American history. For this event the U.S. decided to turn attention away from the international climate and focus on the beauty of the Pacific, which ironically is named for peace.
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 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.

San Francisco belongs to California state in America and located on the west coast of American continent connecting to Pacific ocean, so it has been an important entrance for many ships from east to America including China, Japan, Korea, Russia, etc. California used to belong to Spain and Mexico, until 1848 America won California after United States war with Mexico. At the same year in 1848, gold was found accidently in Sutter’s Mill, California, and the gold rush att...
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.
Gilded age San Francisco stood as a beacon for travelers bound for the western coast of the United States. The most prominent city in the developing west during the latter parts of the nineteenth century and the opening of the twentieth, San Francisco encompassed a range of conflicting identities. This time period marked a transitory stage in the development of San Francisco, evolving from a booming “frontier town” to a “civilized metropolis,” the emerging San Franciscan identity retained qualities from both poles of this spectrum. Chinatown, existing as a city within the city, shared this relationship of extremes with San Francisco. To travelers visiting San Francisco, Chinatown was a necessary stop. The writings in travelogues published during this period describe Chinatown through a mix of revulsion and curiosity, its inhabitants virtuous and sub-human. In short, within the developing city of San Francisco, an expedition into Chinatown remained a visceral exploration of a foreign and exciting environment.
...er caused the city to crumble and the government to pay extreme amounts of money. In addition, residents of San Francisco and other surrounding areas suffered as a result. Thousands died, but even more faced the encumbrance of homelessness. As if that could not worsen, fires went on afterward for as long as three days. Nevertheless, San Francisco transformed like a phoenix; its ashes turned into a beautiful city full of fascinating buildings in a matter of months. 1906, a year of a significant natural disaster, also became a year that spawned knowledge in the field of seismology. No one will ever forget the appalling chain of events that took place during the early twentieth century. The San Francisco Earthquake of 1906 has not only taught seismologists almost everything they now know, but it has also made San Francisco the jewel of the West Coast that it is today.
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.
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...
The San Andreas Fault marks the place where the Pacific Plate and the North American Plate collide, forming a transform boundary. The earthquake occurred when the two plates collided. Pressure built up over time. Then, suddenly, the plates slipped and moved very fast. There’s no way to tell when this could happen. No one in San Francisco was expecting a disaster as great as this.
The Hayward Fault Zone is a geologic blame zone equipped for creating altogether significantly destructive earthquakes. This fault is around 74 mi (119 km) long, arranged for the most part along the western base of the hills with respect to the east side of San Francisco Bay. The Hayward Fault is one of the secondary faults in this diffuse zone, along with the Calaveras Fault to the east and the San Gregorio Fault, west of the San Andreas. The Hayward Fault underlies probably the most thickly populated places in the Bay Area as it keeps running for roughly 50 miles along the foothills of the East Bay. It is crossed by five noteworthy expressways and a few water burrows; BART and other rail lines likewise intersect it at
