The Millau Viaduct Connects two limestone plateaus (the Causse du Larzac and the Causse Rouge), crossing above the Tarn valley below, who’s small winding country roads around the town of Millau used to be heavily congested in holiday seasons as it was the only way across the valley. The Bridge is situated in the communes of Millau and Creissels, in the south of France. 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... ... middle of paper ... ...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.
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.
The building of a new bridge will be done. The question is when. A new bridge is of major importance to the city of Buffalo. It will bring many positives, and barely any negatives. Personally, I have always just thought of a bridge as a way to get from point A to point B. However, the idea of new Peace Bridge's benefits has opened my eyes. The new Peace Bridge may result in a modern day Erie Canal.
This bridge was necessary to the people of Harpswell due to the weather changes making it impossible for the fishermen and their families to cross from island to island. They used their fishing boats when the weather cooperated, but when storms arose and when the water
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

The bridge, Prince Edward Viaduct located in Toronto, Ontario and the Roman bridge, Pont du Gard, located in Vers-Pnt-du-Gard, Gard, France, are both arch bridges that were both built using the development of an arch. The arches on Prince Edward Viaduct and Pont du Gard provide flexibility and assists the overall stability of the structure. Although, the Roman arch bridge was built in 1st c BCE, the arch structure have been improved and was used to built the Prince Edward Viaduct, that was opened in 1918.
The bridge would be 3-dimensional and have two sides. A bucket would be hung from one of the supports in the center connecting the two sides. Weight would be added until the bridge broke and could no longer hold it.
Before the Anzac brifge was built there were two bridges over Johnstons bay. The first bridge was made to get the abbattoirs out of central sydney and relocate them at Glebe Island. That bridge was opened in 1862 and featured a twelve meter swing section on the east of the three hundred and eighteen meter bridge. The second bridge was opened in 1902 and was a swing bridge that was electrically operated. It was designed by Percy Allan, who also designed
This all iron design made the bridge a lot heavier than it was designed for, which added more stress to the truss. This fact, by itself, wouldn’t cause any alarm. However, the bridge itself, was very poorly constructed. The members of the bridge were all different sizes, and they were not connected together properly. Due to the poor construction and eleven years of use, members of the bridge had started to bend due to the stress. Despite bridge engineers inspecting the bridge for eleven years, no one noticed these faults with the bridge. However, the ultimate cause of this collapse, was so tiny, only one of the investigators, after the collapse, noticed it. A tiny air hole was left during the construction of the bridge, “and grew with repeated stress over eleven years” (Escher, 2009). This hole would develop in a crack, due to the changing temperatures and the trains crossing it for over eleven years. This would weaken the overall strength of the bridge. The cold winter air and the weight of the train would ultimately prove to be too much, and the whole bridge came crashing
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...
Chicago is well known for being very close with water. Not only is there Lake Michigan but also the Chicago River that runs through the middle of the city. In the heart of the city bridges help bring boats through the busy city streets and on the outskirts trains are brought across the water. No matter where you are in Chicago, you probably had crossed a bridge to get there.
The bridge model is a three span bridge with 60, 80 and 60. The carriageway is 7 m wide by 1.0 m wide sidewalks along each position. There are in situ diaphragm abutments and pier. The superstructure is built integral with the base. The foundations of the bridge are precast concrete piles with in-situ pile-caps. To avoid unnecessary reactions resulting from thermal expansion of the platform, the abutments are taken as small batteries and flexible enough. Although not enough to fill the back foot diaphragms to resist forces of longitudinal acceleration and braking.
This report covers the superstructure design of the new US 69 Bridge proposal along with a cost estimate for this portion of the project. The old bridges will be replaced with a new four-lane bridge along with a shared use path. The dimensions of this bridge are 77 feet across and 2250 feet in length. Traffic barriers will be placed along the edge, between traffic directions and between traffic and the shared use path.
In this lesson, we explore the history, construction, and restoration of the Longfellow Bridge that connects the cities of Boston, Massachusetts and Cambridge, Massachusetts across the Charles River.
The Central Artery Tunnel Project, more commonly known as the Big Dig, is said to be the largest, most complex and technologically challenging highway project in American history. It is the culmination of decades of planning and forethought and is hoped to alleviate the traffic congestion that has plagued the Boston area since the invention of the automobile. The project incorporates a major underground highway system, a revolutionary cable-stayed bridge, and a series of impressive tunnel crossings, each a considerable feat on their own, all constructed in the midst of a bustling city.
