Have you ever thought about how many bridges are there in the world? I did and I researched everything about the bridges. Let’s get this question first of all. There are six hundred thousand bridges in the United States if we consider all bridges small or big. This number is valid for only United States that means there are so many bridges we can’t even count. However even we have counted them they are built new ones and destroyed old ones day by day so the number will change eventually. It was researched the information about some of famous bridges which are known most by people.
When you ask people around the world “Which bridge is the most famous?” most of their answers will certainly be “Golden Gate Bridge, Brooklyn Bridge or Bosphorus Bridge”. It can be explained why these are famous as the following sentences. These bridges are known most by people because of TV and cinema. Directors have noticed the beauties of these bridges and they wanted to use them in their movies and TV series. They are definitely right these bridges are engineering marvel. They are designed perfectly maybe that is the most efficient reason why they want to ornament their TV series or movies with these perfect designs. In here it is going to explained how these bridges was built, how engineers designed them and how they are still survived and famous.
First bridge that it will be handled Golden Gate Bridge is the oldest one of these three bridges. The bridge was finished and opened in 1937 and people has used it from this year to the present, probably they will use it much more years. The interesting information is that “In the opening the chain was cut whereas people expect that ribbon was cut” (Wikipedia, description). Even the structure was finish...

Steven Hermosillo Professor Wallace Fire Tech 105 15 November 2015 Silver Bridge Collapse According to Wikipedia, Forty-six people were killed in the silver-bridge collapse and another nine people were injured. “The Silver Bridge was an eye-bar-chain suspension bridge built in 1928 and named for the color of its aluminum paint. The bridge connected Point Pleasant, West Virginia, and Gallipolis, Ohio, over the Ohio River” (Wikipedia). This was a highly used bridge serving thousands of cars a day before the collapse.
Bering Land Bridge- during it’s time of existence the bridge was a major factor in migration from Asia to North America; made travel easier because it was on land instead of having to travel by boat
Once again, it is necessary to remember that the Peace Bridge is an important link between the United States and Canada. The PBA states, "There was ten million dollars traveling over the bridge weekly in 1990, presently in 2001 there is 700 million dollars traveling over the bridge weekly. " In addition, 6,000 trucks carrying commercial goods travel over the bridge daily. By the year 2003, the Peace Bridge will reach ultimate capacity. If traffic continues to grow, the bridge will become outdated by 2004.
Not only has it been a huge cultural monument, but it also has changed the economy of the area. The area no revolves so much on tourism and that is where a lot of their money comes from. Originally, all they wanted was access to the mainland because the people were struggling to get by, but once the bridge was made things changed in a different way. This brought a lot of tourism to the area that they were not originally expecting. This was a necessity of the people and turned out to be a great addition to their area once the bridge was made. There was a lot of talk and it took awhile to pass the building of the bridge, but in the end they made a good decision to build the bridge. This bridge is also very unique in it’s own way, being one of the only bridge’s built in this
do credit it to the famous and wondrous Seven Mile Bridge. It should get billing as one of the 7 Wonders In Our Manmade World, and you'll see beautiful
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.
The Jericho Covered Bridge in Kingsville, Maryland was built in 1865 and restored in 1982. The bridge is 100 feet long and cased in cedar planks and timber beams. Legend has it that after the Civil War many lynchings occurred on the bridge. Passersby were supposedly captured on the bridge and hung from the upper rafters. The bridge is very close to my house and I have driven over it several times. The storyteller, age 19, also lives a couple minutes away from the bridge. He has lived in Kingsville, Maryland his entire life. He recalled a dramatic story he had heard from his older brother involving the haunted bridge.
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
When I was a small child, I remember my parents crossing the James River on the ferry in Surry County while taking my brother and me to Jamestown. At the time, I thought it was thrilling to ride the ferry. It was fun to stand out at the bow and watch as we went over the river to the other side where the boats are docked at Jamestown. We fed the birds on the front deck, and I also remember going up into the top of the ferry where they had a seated area that allowed someone to get out of the wind and still be able to see out. As an adult, I no longer have this glowing admiration for the ferry services in Surry. It never fails that when I am approaching the dock; the ferry is pulling away. Thereafter, it will be at least a thirty-minute wait for the next ferry to arrive. As well as, the actual ride across which could be an additional thirty minutes depending on which ferry pulls into the dock. One ferry is extremely slower than the other is. I will go to great lengths to avoid the ferry services to cross the James River to Williamsburg and will rather drive around Newport News than to use the ferry. My husband and I moved to Surry County two years ago, and it would be nice to be able to travel safely to Williamsburg without the added time it takes to cross the James River on the ferry. There has been talk over the years about replacing the ferry services with a bridge; however, those notions are always disregarded. The residents of Surry County would be better served if a bridge were put in place of the ferry at Scotland Wharf.
People who thinks of Thornton Wilder primarily in terms of his classic novella “Our Town,” The Bridge of San Luis Rey will seem like quite a switch. For one thing, he has switched countries; instead of middle America, he deals here with Peru. He has switched eras, moving from the twentieth century back to the eighteenth. He has also dealt with a much broader society than he did in “Our Town,” representing the lower classes and the aristocracy with equal ease. But despite these differences, his theme is much the same; life is short, our expectations can be snuffed out with the snap of a finger, and in the end all that remains of us is those we have loved.
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 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 the wave. On the last day of the bridge's existence it gave fair warning that its destruction was eminent. Not only did it oscillate up and down, but twisted side to side in a cork screw motion. After hours of this violent motion with wind speeds reaching forty and fifty miles per hour, the bridge collapsed. With such a catastrophic failure, many people ask why such an apparently well thought out plan could have failed so badly?(This rhetorical question clearly sets up a position of inquiry-which iniates all research.) The reason for the collapse of the Tacoma Narrows Bridge is still controversial, but three theories reveal the basis of an engineering explanation. (Jason then directly asserts what he found to be a possible answer to his question.)
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
The Bridge by Franz Kafka was a short story published posthumously in 1931 (bio.com). It is a three paragraph story about a bridge. That is grasping on to each side of a ravine. Having never had a visitor until the day
