There is now a linear distance between the two wedges equal to the distance forward the roadway has just moved. [citation needed]. Not only does this give the bridge a dramatic silhouette, but crucially, it also makes the minimum intervention in the landscape. [citation needed], Once the Ministry of Public Works had taken the decision to offer the construction and operation of the viaduct as a grant of contract, an international call for tenders was issued in 1999. This apparatus is capable of taking up to 100 readings per second. Officially opened December 14, 2004. Record breaking viaduct. Between each of them, eleven stays (metal cables) are anchored, providing support for the road deck. The exterior envelope of the stays is itself coated along its entire length with a double helical weatherstrip. The pieces were joined to form the one complete mast, still lying horizontally. The launching advanced the road deck at 600 millimetres (24 in) per cycle which was roughly four minutes long. This performance was mainly due to sliding shuttering. 13 May 2007 – 10,496 runners took the departure of the race from Place de Mandarous, in the centre of Millau, to the southern end of the Viaduct. The westernmost route would be better, longer by 3 kilometres (1.9 mi), but a third of the cost with its three more conventional structures. Five consortia tendered:[citation needed], Piers were built with Lafarge high performance concrete. Number 2 was the tallest across the river number 3 was not mu… [citation needed], The bridge's construction cost up to €394 million,[2] with a toll plaza 6 kilometres (3.7 mi) north of the viaduct, costing an additional €20 million. Displacements of the deck on the abutment level are measured to the nearest millimetre. Simultaneously, a school of international experts representing a wide spectrum of expertise (technical, architectural, and landscape), chaired by Jean-François Coste, was established to clarify the choices that had to be made. The construction consortium was made up of the Eiffage TP company for the concrete part, the Eiffel company for the steel roadway (Gustave Eiffel built the Garabit viaduct in 1884, a railway bridge in the neighbouring Cantal département), and the Enerpac company[15] for the roadway's hydraulic supports. Each of its sections spans 342 metres and its piers range in height from 75 metres to 245 metres, with the masts rising a further 87 metres above the road deck. less than 4 years. Management was handled by Eiffage Concessions.

[citation needed], The Millau Viaduct is on the territory of the communes of Millau and Creissels, France, in the département of Aveyron. A method of bypassing Millau had long been considered, not only to ease the flow and reduce journey times for long-distance traffic, but also to improve the quality of access to Millau for its local businesses and residents. The Millau Viaduct (French: Viaduc de Millau, IPA: [vjadyk də mijo]) is a multi-span cable-stayed bridge completed in 2004 across the gorge valley of the Tarn near Millau in Southern France.The design team was led by engineer Michel Virlogeux and English architect Norman Foster. Les Bâteliers du Viaduc offer small-boat tours on the Tarn that pass beneath the bridge. The farm and its surroundings can accommodate entertainment and tourism promotion activities.[26]. Now it is literally a 5 minute drive at 65 mph. One of the solutions considered was the construction of a road bridge to span the river and gorge valley. Compagnie Eiffage du Viaduc de Millau: Construction start: 16 October 2001: Construction Finish: 14 Desember 2004: Construction Cost: € 394.000.000: Opened: 16 Desember 2004: Toll: From € 8,30 . During 1995–1996, a second definition study was made by five associated architect groups and structural engineers. [2] It was built over three years, formally inaugurated on 14 December 2004,[1][2] and opened to traffic two days later on 16 December. The toll plaza is on the A75 autoroute; the bridge toll booths and the buildings for the commercial and technical management teams are situated 4 kilometres (2.5 mi) north of the viaduct. [citation needed], All the member companies of the Eiffage group had some role in the construction work. The Viaduc de Millau. It follows the Millennium Bridge over the River Thames in expressing a fascination with the relationship between function, technology and aesthetics in a graceful structural form. The 2,000 cubic metres (2,600 cu yd) of concrete necessary for the treads was poured at the same time. © Copyright 2021 Foster + Partners. The Millau Viaduct is the world’s tallest cable-stayed bridge. In March 2001, Eiffage established the subsidiary Compagnie Eiffage du Viaduc de Millau (CEVM), and was declared winner of the contest and awarded the prime contract in August. But the architecture of infrastructure has a powerful impact on the environment and the Millau Viaduct, designed in close collaboration with structural engineers, illustrates how the architect can play an integral role in the design of bridges. The six central spans measure 342 metres (1,122 ft), and the two outer spans are 204 metres (669 ft). - See 2,451 traveler reviews, 1,583 candid photos, and great deals for Millau, France, at Tripadvisor.

The speed of construction then rapidly increased. France, This website uses cookies. The bridge now traverses the Tarn valley above its lowest point, linking two limestone plateaus, the Causse du Larzac and the Causse Rouge [fr], and is inside the perimeter of the Grands Causses regional natural park. Each strand has triple protection against corrosion (galvanisation, a coating of petroleum wax, and an extruded polyethylene sheath). Located in southern France, the bridge completes a hitherto missing link in the A75 autoroute from Clermont-Ferrand to Béziers across the Massif Central. [23], The electrical installations of the viaduct are large in proportion to the size of the bridge. At 984 feet tall, the Eiffel Tower is an impressive structure that soars above the Paris skyline. [1] Because the government had already taken the design work to an advanced stage, the technical uncertainties were considerably reduced. Satellite image of the route before construction of Millau Viaduct #3 Millau Viaduct was designed by Norman Foster and Michel Virlogeux.

Being the tallest of all, it is therefore under the most intense stress. [6][7][8][9], In the 1980s, high levels of road traffic near Millau in the Tarn valley were causing congestion, especially in the summer due to holiday traffic on the route from Paris to Spain. However, while the Eiffel Tower may be France's most famous landmark, it's not the tallest. The objective of the viaduct would not be achieved; because of the toll, the viaduct would be little used, and the project would not solve Millau's congestion problems. The bridge crosses the River Tarn, which runs through a spectacular gorge between two high plateaux. People marvel at its height and elegant design. [citation needed], The construction Millau Viaduct broke several records:[citation needed], Since opening in 2004, the deck height of Millau has been surpassed by several suspension bridges in China, including Sidu River Bridge, Baling River Bridge, and two spans (Beipan River Guanxing Highway Bridge and Beipan River Hukun Expressway Bridge) over the Beipan River. At the bottom of each pylon, a tread of 3–5 metres (10–16 ft) in thickness was installed to reinforce the effect of the deep shafts. The total cost was €20 million.

(4) The upper wedge moves backward, placing it further back along the roadway, adjacent to the front tip of the lower wedge and ready to repeat the cycle and advance the roadway by another increment. The pylons of the Millau Viaduct, which are the tallest elements (the tallest pylon – 244.96 metres (803.7 ft)) were produced and mounted by PAECH Construction Enterprise from Poland. Bridges are often considered to belong to the realm of the engineer rather than that of the architect. Every August, highways in the south of France are clogged with vacationers. '"The Millau Viaduct is a magnificent example, in the long and great French tradition, of audacious works of art, a tradition begun at the turn of the 19th and 20th centuries by the great Gustave Eiffel," … Each half of the assembled road deck was pushed lengthwise from the plateaus to the pylons, passing across one pylon to the next. This new bridge, opened on the 14th December 2004, replaces the bridge crossing the River Tarn in the centre of the town of Millau. In January 1995, the government issued a declaration of public interest to solicit design approaches for a competition. Historia. The mast was then tilted upwards, as one piece, at one time in a tricky operation. In this way, each mast was erected on top of the corresponding concrete pylon. Viaduc de Millau: Spectacular construction! The concept and design for the bridge was devised by French designer and structural engineer Dr Michel Virlogeux. These are composed of 173 central box beams, the spinal column of the construction, onto which the lateral floors and the lateral box beams were welded.

The wedges were hydraulically operated, and moved repeatedly in the following sequence: (1) the lower wedge slides under the upper wedge, raising it to the roadway above, and then forcing the upper wedge still higher to lift the roadway; (2) Both wedges move forward together, advancing the roadway a short distance; (3) The lower wedge retracts from under the upper wedge, lowering the roadway and allowing the upper wedge to drop away from the roadway; the lower wedge then moves back all the way to its starting position. The design team was led by engineer Michel Virlogeux and English architect Norman Foster. He worked with the Dutch engineering firm Arcadis, responsible for the structural engineering of the bridge.[14]. The Royal Gorge suspension bridge in the U.S. state of Colorado is also higher, with a bridge deck approximately 291 metres (955 ft) over the Arkansas River. [10] The first plans for a bridge were discussed in 1987 by CETE, and by October 1991 the decision was made to build a high crossing of the Tarn by a structure of around 2,500 metres (8,200 ft) in length. In high winds, they continuously monitor the reactions of the Viaduct to extreme conditions.
