An Engineered Wonder of the World
"This bridge needs neither praise, eulogy nor encomium. It speaks for itself. We who have labored long are grateful. What Nature rent asunder long ago, man has joined today." This is a quote from Joseph Strauss, the engineer that designed the Golden Gate Bridge. The Golden Gate Bridge is truly a piece of engineering excellence. It stretches for almost 9,000 feet over the San Francisco Bay, in San Francisco, California. The bridge has faced many problems during the designing process, construction, and even to this day it produces controversy. The final result of the bridge, however, is an amazing engineering feat that will be around for a long time.
To begin, in 1916, James H. Wilkins had the idea to connect the San Francisco Peninsula to the rest of Northern California. After eight years, the United States War Department approved the project for the bridge. Another four years passed, and Joseph Strauss is named the designer for this new bridge (“Golden Gate Bridge Fast Facts”). In brief, Joseph Strauss was a structural engineer who studied at the University of Cincinnati. Strauss had already constructed hundreds of drawbridges, but he wished to build, "the biggest thing of its kind that a man could build." Therefore, when Strauss was approached to design a bridge that would span over the Golden Gate Strait, he was very excited (“American Experience”). Originally, Strauss wanted the bridge to be a cantilever-suspension hybrid design. However, this design was not immediately accepted. During a four year span between 1925 and 1929, and through many consultations with the Advisory board of engineers, the bridge revised to solely a suspension bridge. The main reason for this is likely Leon Moisseiff...

“It was designed with a twenty-two foot roadway and one five-foot sidewalk” (Silver). The silver bridge is a very long bridge. “An eye-bar is a long steel plate having large circular ends with an "eye" or hole through which a pin is used to connect to other eyebars (to make a chain) or to other parts of the bridge.” according to Richard Fields. The whole bridge was built using the eye-bar suspension.
The Bailey Island Bridge is located in Harpswell, Maine on Route 24. Before the making of the bridge, the fishermen that lived on Bailey’s Island wanted a bridge that connected their island to Orr’s Island. The town of Harpsweell made and voted on their decisions in the weekly town meetings (“Bailey”). The project was stalled because of some of the mainlanders in the town, but it was brought back up for discussion in 1912. They first agreed on a “road” which would connect the two islands and would be constructed with timber. This was to cost $3,000. The cost quickly reached $25,000 at a later town meting because they decided to build the bridge with stone and concrete instead. Once the legislature decided to pass a bill stating that it would fun state’s highway and bridge projects, they decided to move forward with the project (Hansen, 36).
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...
The Golden Gate bridge, standing as an icon of roadway innovations, took multiple engineers years to design and complete. They could not just simply build an ordinary bridge. They had to take into consideration the physics behind it, as well as, what kind of effect the environment would have upon the bridge. The bridge sits along one of the most active fault lines in the world, so engineers had to make sure their bridge could withstand a little movement. Today the Golden Gate bridge still stands tried and true, as does many other innovations that 20th century engineers came up with.
Since it would be easier and less expensive to build a bridge rather than a tunnel, a bridge was initially thought to be a better solution. However, to construct a bridge over the Hudson River it would require a minimum clearance of 200 ft. for ships to travel to and from Hudson River ports. Since the Manhattan side of the Hudson did not meet the 200-foot elevation requirement needed for a bridge, new and expensive apparatuses would have to be built on the New York side. Also, a bridge would be affected by poor weather conditions more than a tunnel. In 1913, the joint coalition finally decided to construct a tunnel.2
(the sudden collapse of a national landmark, the Bridge of San Luis Rey) which five people were crossing at the time of the disaster. All five were killed instantly: a little boy, a young girl, a wealthy old woman, an old man, and a youth. Brother Juniper is shocked into a metaphysical thought: “If there were any pattern in the universe at all, any plan in a human life, surely it could be discovered mysteriously latent in those lives so suddenly cut off. Either we live by accident and die by accident, or we live by plan and die by plan. And in that instant Brother Juniper made the resolve to inquire into the secret lives of those five persons, that moment falling through the air, and to surprise the reason of their taking off” (Wilder, 5).
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 Arch is the tallest man made monument in the United States, the only monument taller than the Arch is the Eiffel Tower. The Arch was built out of stainless steel and concrete, there are 142 sections or what looks like panels from the ground of the stainless steel pieces. One could not pick up the Gateway Arch if they tried as it weighs 43,000 tons! The Jefferson National Expansion Memorial is actually 91 acres which includes roughly 60 acres of Arch grounds and the remaining acres include the Old Courthouse and some of the surrounding streets. This area corresponds with the original site of the French colonial town of St. Louis which is considered the oldest European city in the Midwest. It was decided to create the park here due to St. Louis’s major role in Westward Expansion, as I have mentioned before. Some of the key events that involved St. Louis in what would eventually become the expansion of the United States to what we all know it as today are as follows. St. Louis is the place where the Santa Fe and the Organ Trails originated, and the place were Lewis and Clark started their exploration, and where formal possession of the Louisiana Purchase was taken. These are just some of the fun facts I learned about the Arch on my

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

For this bridge its fall was inflicted by an unknown patron. One who’s identity or existence we never see verified. The record of the fall is short in the story described as only being for a moment. Then the bridge was finally introduced to “the sharp rocks which had always gazed up at me so peacefully from the rushing water”. Rocks gazing peacefully? This is almost as absurd as a bridge turning around. An action that the bridge itself cannot seem to believe it is doing. This attempt by the bridge was his final effort before his fall. I cannot even picture how a bridge would turn around and attempt to look on his back. The question that comes to my mind is how can a bridge see what’s on his back? If this book is trying to make us believe that this bridge is a human, or has human like qualities. Then how flexible a person is this bridge? Because I know very few people who can see whats on their back. Especially without turning so much that anything on their back would fall off. So is this bridge so inflexible that it breaks itself by turning around or is it trying to buck off its attacker unintentionally? This answer is never answered due to the story ending shortly thereafter this scene. With the short fall of the bridge onto the sharp rocks it had stared at for the entirety of its life. The events before and during the fall of the bridge was the main issue I had with my thesis that the bridge was
My family and I were able to cross the famous bridge a few times in the car as we traveled a bit around California. The view from the bridge was beautiful during the day and as well as the night. It was nice during the day to see the sun sparkling on the water as boats sailed by but appealing during nightfall because of the bright lights on the bridge. Also, the city lights around it brought out the overall awe of the bridge. During one of our passing of the bridge we were able to make a quick stop at the top of the hill and take a few family pictures together with the bridge. My brother would tease me every time anyone brings up our visit to the Golden Gate Bridge because I was afraid to stand near the edge of the mountain to take our family photos since I imagined I was going to slip and fall. Furthermore, as we traveled through the bridge I had noticed telephone posts on either side of the bridge. These telephones were for the suicidal people who thought it was time to end their lives. The telephones were used to connect those who were suicidal to a counselor to help talk them out from committing such a tragedy. They may have helped saved plenty lives. It has been known by many that the Golden Gate Bridge is one of the many bridges that countless of people tend to go to in order to attempt
