The Brooklyn Bridge's development is one of the greatest accomplishments in United States history. It had also helped New York out on faster transportation around the 20th centuries. It was an endeavor that required plenty of time spent on it, sacrifice, and inventiveness by its designers and in addition the other workers to finish. The Brooklyn Bridge was the longest suspension connect,the first to utilize steel-wire,and overwhelmed the New York City horizon as the tallest structure in the western side of the equator. ( Hiden 476)
Since 1883, the Brooklyn Bridge goes across the East River in New York City. Surprisingly, it’s making took only 14 years. Even with all its down sides in the creating, it now has tons of people passing through

His making of the bridge was soon known as the “Brooklyn Bridge” and its construction started in January 3, 1870. Its designer John Augustus Roebling moved to western Pennsylvania, where he tried to become a farmer but failed. He then later moved to Harrisburg, where he then knew his work was to be a civil engineer as he established a great wire cable factory.That’s when he then started creating bridges across rivers. Because his other successful bridges he had achieved, the New York legislators accepted his plan in the making for the Brooklyn Bridge in 1867. Just when John and his crew members were going to start construction in 1869, John had his foot crushed by a ferie and died 24 days later. This is when his son Washington Augustus Roebling had to take over as the assistant engineer. ( History.com …show more content…
The blocks used on the bridge were actually built in Maine and later shipped into New York. The Brooklyn Bridge total length was 5,989 feet and with a width of 85 feet. Its height was 41m tall and weighed about 14,680 tons.
With John being dead and his son Washington being disabled, he had to bring in is wife to take charge with the mathematics portion. Where they went with John’s idea of putting the roadways lighter so there could be less stress on the cables. Even with his idea, an unexpected blast wrecked one caisson, a fire damaged another, and a cable snapped and crashed into the river. Despite the problems the construction still continued at a fast rate.
It’s crazy how this bridge is the second busiest bridge in New York City. Even the length for the Brooklyn Bridge is just amazing 3,640 feet amazing right? It was even the first suspension bridge to use steel for its cable wire . Also, the first bridge to use explosives in a dangerous underwater device called a caisson.(“ Brooklyn Bridge”) Meanwhile, at the time it was built, the Brooklyn Bridge was also crowned the longest suspension bridge in the world. A little fun fact would be when the bridge had first opened they would charge 5 cents for every vehicle that went through it . The bridge was even given special governmental protection. Many people were even terrified and making a scene that the bridge was going to fall into the river.
Have you ever thought about driving over a suspension bridge held up by cables? That’s what the Mackinac Bridge is. With the building of the Mackinac Bridge there has been many positive effects that have come out of it.
Without a concrete reason for the bridge's failure, every suggested reason was researched until proven incorrect” (Silver). There were many reasons that were suggested, but could not be proven correct due to the collapse. Wikipedia states that “A small crack was formed through fretting wear at the bearing, and grew through internal corrosion, a problem known as stress corrosion cracking.” The failure of the bridge was caused by a defect in one of the eye-bars on the north side causing the other side to collapse as well. “Stress corrosion cracking is the formation of brittle cracks in a normally sound material through the simultaneous action of a tensile stress and a corrosive environment.
It became a link between Fort Erie, Canada and Buffalo, New York. The bridge is over one mile long, 5,800 feet, and holds three lanes of traffic. The center lane may go north or south depending on the volume of traffic. In 1934, the Great Depression caused a change.
On May 24, 1854, construction began of the Victoria Bridge. This was a difficult task for the workers given the size of the bridge (“almost two miles in length from shore to shore” ) was the largest construction project during this period of time. Moreover, the construction of the bridge did not cease during the winter months. Therefore, many of the workers on the bridge would continue even while the St-Lawrence River froze underneath their
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).
Bridge. After his death at 74, the newspaper advocated the construction of what is now
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.
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...
With this recognition, he resigned and started the Keystone Bridge Company in 1865. He built a steel-rail mill, and bought out a small steel company. By 1888, he had a large plant. Later on he sold his Carnegie Steel Company to J. P. Morgan's U.S.
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...
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.)
The current size, inherent values, and economic status of the United States owes greatly to the paramount figures and events that took place during the Early National Period of the country. However, while there is no doubt that such events- and the figures behind them- were of great importance and have molded the country into the pristine product that it is today, the various construction projects of that time have gone largely unnoticed. Canals, being one of the most prominent advances in transportation, are prime examples of forgotten catalysts of the American nation. The construction of canals- particularly the Erie Canal- during the 19th century played a key role in the geographic, economic, and cultural development of the country by allowing an easier and faster mode of transport, and contributing greatly to the preservation of the Union during the Civil War.
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
