[citation needed], The bridge road deck was constructed on plateaus at both ends of the viaduct, and pushed onto the pylons using bridge launching techniques. During the launching, the road deck was also supported by eight temporary towers, which were removed near the end of construction. [5] The bridge has been consistently ranked as one of the greatest engineering achievements of modern times, and received the 2006 Outstanding Structure Award from the International Association for Bridge and Structural Engineering. [citation needed], The seven masts, each 87 metres (285 ft) high, and weighing around 700 tonnes (690 long tons; 770 short tons), are set on top of the concrete pylons. The toll plaza is protected by a canopy in the shape of a leaf, formed from tendrilled concrete, using the ceracem process. Millau-viadukten (fransk:Viaduc de Millau) er en skråstagsbro beliggende i Frankrig.Broen krydser dalen, som har gennemløb af Tarn-floden, tæt på byen Millau i det sydlige Frankrig. - Check out Tripadvisor members' 3,890 candid photos and videos. [citation needed], The pylons, road deck, masts, and cable stays are equipped with a multitude of sensors to enable structural health monitoring. The A75, with the A10 and A71, provides a continuous high-speed route south from Paris through Clermont-Ferrand to the Languedoc region, thence to Spain, considerably reducing the cost and time of vehicle traffic travelling along this route. At times of low traffic volume, the central booth is capable of servicing vehicles in both directions. It constructs bridges and highways. They also applied the launching technology. There were four shafts per pylon; 15 metres (49 ft) deep and 5 metres (16 ft) in diameter, assuring the stability of the pylons. The cost of this work amounted to € 5.8 million: Unusually for a bridge closed to pedestrians, a run took place in 2004, and another on 13 May 2007:[citation needed], 2004 bridge across Tarn near Millau, France, Learn how and when to remove this template message, International Association for Bridge and Structural Engineering, information and communication technologies, Richard Hammond's Engineering Connections, List of longest cable-stayed bridge spans, "The 10 greatest engineering feats of the decade", "10 greatest modern day engineering marvels of the world", "Top 10 modern engineering marvels in the world", "Décret 2001-923 du 8 octobre 2001 approuvant la convention de concession passée entre l'Etat et la Compagnie EIFFAGE du viaduc de Millau pour le financement, la conception, la construction, l'exploitation et l'entretien du viaduc de Millau et le cahier des charges annexé à cette convention", "ARCADIS tekende voor hoogste brug ter wereld", "Final hydraulic launch successfully closes last gap in the Millau Viaduct in the south of France", "Database of ICT companies in the Walloon Region", "The art of cable-stayed bridges on the Meuse and all over Europe", https://www.youtube.com/watch?v=wJWblykm9Tc, https://acivengstudent.com/2019/09/06/millau-viaduct-bridge/, https://www.youtube.com/watch?v=DlbTNJ0AU1Y, "A specific surfacing extensively tested!

[citation needed], The rest area of Brocuéjouls, named Aire du Viaduc de Millau,[24] is situated just north of the viaduct, and is centred on an old farm building named 'Ferme de Brocuéjouls'. The stays connecting the masts and the deck were then installed, and the bridge was tensioned overall, and weight tested. Being the tallest of all, it is therefore under the most intense stress. The exterior envelope of the stays is itself coated along its entire length with a double helical weatherstrip. [citation needed], The Eiffage group, which constructed the Viaduct also operates it, under a government contract, which allows the company to collect tolls for up to 75 years. On 15 July 1996, Bernard Pons, minister of Public Works, announced the decision of the jury, which was constituted of elected artists and experts, and chaired by Christian Leyrit, the director of highways. It weighs around 2,500 tonnes (2,500 long tons; 2,800 short tons). [citation needed], In March 2002, the pylons emerged from the ground. [citation needed]. Displacements of the deck on the abutment level are measured to the nearest millimetre. These are designed to detect the slightest movement in the Viaduct, and measure its resistance to wear-and-tear over time.

Près du viaduc est un centre d’accueil permanent avec les vues stupéfiantes du pont et en travers de la vallée sur laquelle il enjambe. The abutments are concrete structures that provide anchorage for the road deck to the ground in the Causse du Larzac and the Causse Rouge. The viaduct represented a detour, reducing the number of visitors passing through Millau and slowing its economy. Each half of the assembled road deck was pushed lengthwise from the plateaus to the pylons, passing across one pylon to the next. A further advantage of this process was to make negotiating the contract easier, reducing public expense, and speeding up construction, while minimising such design work as remained for the contractor.

The metallic road deck, which appears very light despite its total mass of around 36,000 tonnes (40,000 short tons), is 2,460 metres (8,070 ft) long and 32 metres (105 ft 0 in) wide. [25] It was inaugurated by the prefect of Aveyron, Chantal Jourdan, on 30 June 2006, after 7 months of works. The surface is somewhat flexible to adapt to deformations in the steel deck without cracking, but it must nevertheless have sufficient strength to withstand motorway conditions (fatigue, density, texture, adherence, anti-rutting etc.). [citation needed], Detailed studies were carried out by the successful consortium, steered by the highways authority until mid-1998. The builder claims that the lifetime of the bridge will be at least 120 years. To allow for deformations of the metal road deck under traffic, a special surface of modified bitumen was installed by research teams from Appia (company) [fr]. Other extensometers, electrical this time, are distributed on top of P2 and P7. The concept and design for the bridge was devised by French designer and structural engineer Dr Michel Virlogeux. The mast was then tilted upwards, as one piece, at one time in a tricky operation. With a span of 342 m, the Eiffel Tower would fit sideways between two piers. The 'ideal formula' was found after two years of research.

In addition to hydraulic jacks on each plateau pushing the road decks, each pylon was topped with a mechanism on top of each pylon that also pushed the deck. 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 Millau Viaduct is known as "the structure that broke all the records": with its often dizzying figures, it is sometimes difficult to grasp in human terms. The decision to proceed by grant of contract was made in May 1998; then in June 2000, the contest for the construction contract was launched, open to four consortia. (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 technical difficulties were too great, and the bridge would be dangerous and unsustainable; the pylons, sitting on the. The upper and lower wedge of each pair pointed in opposite directions. Depending on their length, the cable stays were made of 55 to 91 high tensile steel cables, or strands, themselves formed of seven strands of steel (a central strand with six intertwined strands).
