One of the wonderful engineering techniques in building this bridge was the use of steel. Its maximum height is 343 meters, but the span is 46 kilometers, 280 meters from the bottom, but actually the bridge is very light. There seems to be 242,000 tons, steel is not structurally used, the weight of the bridge is more than twice the weight. Steel is a much stronger material than concrete, so we can support more weight with less mass. The actual road deck is almost completely made of steel, weighing only 36,000 tons.
Construction of a bridge is an important means to overcome natural obstacles such as rivers and canyons. As of 2015, Millau Viaduct, which is accelerating the improvement of bridge construction technology, is at the forefront of this technology. Millau is the highest bridge in the world with a height of 343 meters (1,125 feet). This 4-lane bridge opened in 2004 is a stretched bridge over the Tarn valley near Milo in the south of France. This bridge is the tallest building in France, higher than the Eiffel Tower.
This project was proposed by the owner, Compagnie Eiffage du Millau Viaduct (CEVM) and customer SETEC, beyond Tarn Gorge via a viaduct / road bridge. All designs must meet design requirements, but Fosters recognizes that the bridge brings some new problems. The tests showed that the driver had problems with such high, long and thin structures with only two lanes on either side. The solution is to tilt the bridge 3% to improve the visibility of the road and increase the cost by increasing the length of the bridge to 5 kilometers to bend the whole structure and reduce floating. To prevent the driver from disturbing the beautiful scenery, the width of the hard shoulder on both sides has been expanded to 3 meters. The design of the emergency call is 500 meters on one side along the length.
Aveleon's Millau Viaduct opened in December 2004, was designed by Michel Vilogy of French engineer and designed by Sir Norman Foster, a British architect. This structure spans Tarn, with a boundary length of 2,460 meters in one and a maximum of 343 meters in a tower above the valley. It is the highest diagonal bridge in the world. This bridge was awarded the 2006 International Bridge and Structural Engineering Excellence Structure Award. The unique highway structure has become a predictable art work. More than 1 million tourists are gathered in the viaducts every year. Therefore, the Milo Viaduct becomes an object between the Eiffel Tower and the Eiffel Tower, people all over the world will appreciate the building. Millau Viaduct is actually higher than the Eiffel Tower
