The Millau Viaduct is the final link in the A75 AutoRoute, a superhighway which stretches from Clermont-Ferrand to Pezenas. This is a large, continuous highway where cars can travel at speeds exceeding the normal speed limit, and is long and straight, allowing cars to travel right though France directly and quickly.
The Millau Viaduct is the tallest suspension bridge in the world, with its tallest pylon measuring to 343 m height, and total weight measured at 242,000 tonnes. The road itself stretches for 2.46km and is 280m above the valley floor. The weight of the road deck is a whopping 36,000 tonnes. The steel road deck, 4.2m thick, has a width of 32m, wide enough for two lanes of traffic in each direction. The total amount of concrete used on the structure was 205,000 tonnes.
One of the great engineering feats when building this bridge was the use of steel. Despite its maximum height of 343m span of 2.46km, 280m above the valley floor, the bridge is actually quite light. 242,000 tonnes seems like a lot but without the use of steel on the structure, this bridge would have been more than twice as heavy. Steel is a much stronger material than concrete, so can support more weight with less mass. The actual road deck, which is comprised almost entirely of steel, only weighs 36,000 tonnes. The other 206,000 tonnes comes primarily from the massive pylons, which are m...

...was reduced, and the bridge was guaranteed a longer life.
The Hampden Bridge was built to replace the Wagga Wagga company bridge, a toll bridge that was constructed in 1862. The Hampden bridge was built as it would provide the main and one of the only links between North Wagga Wagga South Wagga Wagga, which were divided by the Murrumbidgie river.
The Hampden Bridge was a great advantage the community of Wagga-Wagga as it enabled quick easy access over the Murrumbidgie River so as to cross from North to South Wagga Wagga.
Some of the disadvantages of the bridge were that after 100 years of use, in 1975, the bridge was starting to fall apart and eventually, after a few years, the maintenance cost of the structure was starting to get to high so the Wagga Wagga council closed the bridge, and currently there are plans in place to demolish the bridge in the future.

- A bridge is a structure ,built by many different materials, to travel over physical objects. For example, bridges were made over bodies of water, roads or intersections, and valleys. The first welded road bridge was designed by Polish engineer Stefan Bryla in 1927.There is an average of about 607,380 bridges throughout the Unites States. There are many different bridges throughout the world and there is also different causes for bridges. There are also many different designs that all have different purposes and apply to different situations.... [tags: Bridge, Bridges, Box girder bridge]

- ... Spokane Street was completed in 1960. The Battery Street Tunnel was the vital "missing link" to connect the new waterfront structure with Aurora Avenue / SR 99. The tunnel was dug beneath Battery Street, with minimal disruption to surrounding buildings. Work started in September 1952, and it opened to traffic in a grand ceremony on July 24, 1954. Planning of the tunnel was a long process, with extensive discussion of key features such as a ventilation and fire protection systems. The automatic deluge sprinkler system was believed to be the first such system installed in a vehicular tunnel.” The ventilation system sampled and recorded carbon monoxide levels, and the sprinkler was controll...

- ... It’s been the venue for significant cultural events like the first modern bungee jump in 1979, the last Concorde flight in 2003 and a handover for the Olympic Torch relay in 2012. This bridge has made a rather small city in England notable because of its long lasting structure. The bridge towers are not identical in design. The Clifton tower has sides cut-outs, the Leigh tower has more pointed arches. The 25metre tall Leigh Woods tower stands on top a 34 metre red sandstone-clad abutment. In 2002 it was people found out that the tower was not a solid as it could but it did contain 12 vaulted chambers up to 11 metres high, linked by only shafts and tunnels....

- Introduction A bridge is required to span a gorge in New Guinea. The goal of this project is to design a bridge that meets the requirements for that bridge and then construct and test that bridge on a 1:20 scale. The requirements for the bridge are that it has to span across the 600mm (12m to scale) wide gorge which has two square flat areas on either side of the bridge which are 100mm (2m to scale) wide. The bridge must be able to hold the maximum possible weight while remaining as light as possible.... [tags: Bridge, Truss, Truss bridge, Covered bridge]

- Abstract: This report is an analysis of a suitable bridge design to span across a 300mm gap while also being able to support maximum load. Introduction: This report will investigate different bridge designs, from the gathered information a pasta bridge will be constructed replicating the bridge that: 1) Holds sufficient weight 2) Is economically viable 3) Has pleasing aesthetics The bridge must have enough deck room to accommodate a matchbox car. The bridge design that seems most appropriate will be scaled and down and constructed than tested.... [tags: Bridge, Bridges, Moon bridge, Arch]

- Johnny Tran 11-14-14 Physics Period 4 There are many types of bridges. Some bridges has many strength and weaknesses. For example, a beam bridge’s weakness would be that you have to use a lot of stone starting up from the ground. Another example would be how a suspension bridge’s strength would be it flexibility, like the Golden Gate Bridge. The engineering process for a bridge would be to first make sure everything will be symmetrical. Secondly, from that symmetrical blueprint, the construction of the bridge is now good to go....

- About eighty years ago, engineers were able to build a bridge on time and within budget with no problem; today, most of the projects take extra time and money to finish. What exactly happened between now and eighty years ago that caused such a drastic shift. It is clearly not the engineers nor the technology; in fact, those have only improved over time. Today, engineers are faced with much more than designing and building the infrastructure, as they were before. They compete with politicians for funds, fight for the safety of workers, and protect our environment by adhering to the numerous laws and acts set forth by the government....

- Kevin Briggs has resided as a member of the California Highway Patrol for over 23 years with assignments including the Golden Gate Bridge. His job required him to be alert at all times. However, it was not crime he often patrolled for, but suicide attempts. During the duration of this time, he has helped prevent hundreds of people from taking their own lives, which was the main topic of this TedTalk. The presentation was given in March of 2014 at a TedTalk studio location in Vancouver. As for his audience, there was no light illuminating them so I was unable to tell what race they consisted of.... [tags: Suicide, The Bridge, Golden Gate Bridge]

- ... Suspension bridges are visually appealing and light yet strong and durable. Suspension bridges are made from enormous cables that reach from one end of the bridge to the other. These cables rest on top of high towers and swoop down. They are fastened by anchorages that are on both ends of the bridge, which help stabilize the bridge. Most of the weight of the bridge is carried by wires that drop to the road surface from the main cables. These wires help evenly allocate the weight of the bridge and keep the cables sturdily in place.... [tags: bridge, ocean, distance]

- The Bloor Street Viaduct is a landmark bridge linking the eastern part of Toronto with the downtown core. Completed in 1919, the controversial bridge spans 490 meters across and 40 meters in the air above the Don River valley. (Carr 165-166)Designed by Edmund Burke and pushed through by public works commissioner Rowland Harris, the bridge plays a central role in the history of Toronto and in the Michael Ondaatje’s novel In the Skin of a Lion. The description of constructing the bridge in the second chapter of book one introduces the reader to several important characters and themes that carry throughout the narrative but whose importance and connection are not fully realized until much later...
