The Brooklyn Bridge was a feat of modern technology. Its construction spanned from 1869 to 1883, or fifteen years over the lives of its three creators. The first, who was also the designer, was John Augustus Roebling. Many thought it impossible for his plan to succeed, as most other suspension bridges had failed under certain circumstances, but he was determined to prove them wrong. In 1867 his plan was approved by New York legislators and just two years later construction began. Throughout the years of construction, many died, including Roebling himself. After his passing, Roebling’s son, Washington A. Roebling, took his place as chief engineer. For most of the time afterwards, he worked well in this place, but after getting what was called…
At the time the design and the execution of the Niagara Falls Suspension Bridge was revolutionary, however, it’s original design was unable to keep up with the massive surge in transportation and the tremendous increase in the size of…
The bridge was built to be take the traffic away from the Hoover Dam which had just turned 75 years old and cannot hold the traffic anymore. The Hoover Dam was not able to hold the 14,000 thousand cars that drive across the dam every day. To help preserve the dam Arizona and Nevada built The Mike O’Callaghan-Pat Tillman Memorial Bridge. This was a huge project between both states that would end up cost them $240 million.…
In 1869, John took engineers, businessmen and politicians on a bridge tour to see the bridges that he had built. The group was impressed…
The bridge was a giant success. It made large profits and proved to be very convenient. As a result, plans to construct more bridges were set into motion. In 1792, the…
Although the MOD has been responsible for most of the developments that occurred to the tunnels during their history, other local developments also had a big impact, particularly the work of Isambard Kingdom Brunel. Brunel was a famous engineer who built the Box Tunnel, which opened in 1841 after fourteen years of construction. This was an important development which helped realise the industrial potential of the area. The improved railway links helped the quarry develop as it allowed the stone that the quarry produced to be transported around the country quickly and easily.…
There was a plethora of complications involving the bridge. On May 30, 1883, the bridge was on the verge of collapsing which caused a stampede that resulted in about 27 deaths. In the early 1900s, many cars fell into the East River due to the lack of strong, permanent railing. This was corrected as soon as possible. Also, the bridge’s aerodynamics had not been worked out. The bridge wasn’t tested for wind tunnels until the 1950s, but thankfully the structure saved many people from getting hit by 100mph+ winds. Did you know that waves play an important role in the making…
Assignment Discovery Online Curriculum Lesson title: Famous Bridges Grade level: 6-8, with adaptation for older students Subject area: Physical Science, Technology Duration: Two class periods Objectives: Students will: 1. Understand the benefits and drawbacks of different types of bridges. 2. Investigate the history and structural challenges of a prominent bridge. 3. Think about the challenges involved in building bridges. Materials: The class will need the following: • Computers with Internet access (optional but very helpful) • Reference materials on bridges Each group of three or four students will need the following: • Research material about a particular bridge (Web sites and books suggested below) • One long piece of butcher block paper • Pencils, colored markers, and crayons Each student will need the following: • One copy of the Classroom Activity Sheet: Bridge Research and • One copy of the Take-Home Sheet: Longest Suspension Bridges in the United States This lesson plan can be enhanced by purchasing a copy of the documentary Bridges: Design and Function at our School Store. The program airs on the Discovery Channel February 12, March 19, April 23, and May 28, 2001. Procedures: 1. Introduce the lesson by showing the class a picture of a popular bridge, such the Golden Gate Bridge (San Francisco) or the Brooklyn Bridge (New York City). Ask students to imagine what might happen if all the bridges in New York City or San Francisco were suddenly shut down. Then help the class brainstorm some ways that bridges affect our lives. For example, 1…
In conclusion the I-35W Bridge’s design had some flaws which led to the collapse of it in August 1, 2007 and in this paper we spoke about the structural form of the I-35W bridge, some circumstances that led to the collapse, why the bridge fell and some post-effects of the collapse. If the construction company have calculated that the bridge was already in enough stress and not placed the construction material above the design flaws, which were the gusset plates, the collapse would have been…

When you hear the word bridge, I’m sure the first thing that comes to mind is connection. Yes, connection is such a vague word when we talk about a bridge but it blossoms in variety and definitions when we specify the Brooklyn Bridge. The Brooklyn Bridge is the first bridge built in New york City 1883. The first of many construction work that would build the well known juggernaut of a city that we have here today. Many people view the Brooklyn Bridge as a symbol of new york city and for great reason,. The Brooklyn Bridge connected Brooklyn to Manhattan island and was the upstart of urban working and a spike in business in the city.…
During the late eighteenth and early nineteenth centuries, the new nation known as the United States of America began to develop plans to improve transportation into the interior and beyond the great physical barrier of the Appalachian Mountains. A major goal was to link Lake Erie and the other Great Lakes with the Atlantic Coast through a canal.…
One of the problems that were faced in building the canal was engineering. A problem within that was that the Atlantic and pacific oceans were at different elevations, because of that a set of locks were needed. A lock is a section of a waterway, usually a canal that is closed off with gates, in which vessels that go through it are raised or lowered by raising or lowering the water level of that section. A plan was devised of a set of three locks, which were massive. Digging through the continental divide was not an easy task either, moving the earth was aided by filling railroad cars and taking the dirt away. The largest earth dam ever built was part of this canal building too. The builders faced fourteen crosses of the Chagros River, which during storms the muddy channel swelled to an intense flood, which drowned excavation sites and machinery. Landslides…
The Erie Canal finished in 1825 went from Lake Erie to the Hudson River and the Atlantic Ocean. It was built in the search for a better way of transportation from the Old Northwest to the East Coast. The Erie Canal seemed impossible to build by many but it was eventually built overcoming some challenges along the way. The Erie Canal had many positive effects on America but had a few negative consequences. The difficulty in the transportation of goods from Old Northwest to the East Coast lead to the construction of the Erie canal which seemed impossible but is completed successfully and impacted America in many ways.…
The Panama Canal, the way to cheat the Oceans. In 1914, when the Panama Canal was finished, it changed the world of shipping goods, affecting America in many ways. There were many steps taken in getting the Panama Canal to where it is today. In not only it’s economical state but, where it is on Earth. Many lives were given, and millions of dollars were spent to build the Canal. There was a lot of hope in the building of the Canal, but there was also a lot of hatred and uneasiness towards the Canal. After the Canal was finished, thousands of ships would use it, but after a few years there were already ships too large to pass through. The thought of expansion was always in the backs of architects heads’. The thought of expanding the canal soon…
