[1] Because the government had already taken the design work to an advanced stage, the technical uncertainties were considerably reduced. These are situated on the deck, on the pylons, and on the masts. The 2,000 cubic metres (2,600 cu yd) of concrete necessary for the treads was poured at the same time. 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. [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. One of the solutions considered was the construction of a road bridge to span the river and gorge valley. The bridge, made out of steel and concrete, gives the viaduct a strong fine structure with only 7 points along the construction supporting it and 1,500 tonnes of live wire covering the surface of the bridge. [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. 3. People marvel at its height and elegant design. The idea is to avoid running water which, in high winds, could cause vibration[dubious – discuss] in the stays and compromise the stability of the viaduct. Any delay was to cost them 30,000 dollars a day in penalties. Millau [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.

Bridges are often considered to belong to the realm of the engineer rather than that of the architect. The design team was led by engineer Michel Virlogeux and English architect Norman Foster. 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. [citation needed], The competition was relaunched: five combinations of architects and structural engineers, drawn from the best candidates of the first phase, were formed; each was to conduct in-depth studies of one of the general designs. [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'. [citation needed], Twelve fibre optic extensometers were installed in the base of pylon P2. It is part of the A75 to link Paris with Barcelona. Although historically the river was the geological generator of the landscape, it is very narrow at this point, and so it was the second reading that suggested the most appropriate structural solution. It is 343 meters high, a world record. It comprises eight spans. This system can distinguish between fourteen different types of vehicle.

After this, the temporary pylons could be removed. Now it is literally a 5 minute drive at 65 mph. During 1993–1994, the government consulted with seven architects and eight structural engineers. 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 Viaduc de Millau. less than 4 years. Explore Aug 5, 2012 #232 On se demande comment c'est possible de faire des choses pareilles : une merveille ! Displacements of the deck on the abutment level are measured to the nearest millimetre. With a … Other extensometers, electrical this time, are distributed on top of P2 and P7. The builders, Eiffage, financed the construction in return for a concession to collect the tolls for 75 years,[2][3] until 2080. However, according to the minister, he did not envisage building a counterpart in, This bridge was featured in a scene of the 2007 film, This page was last edited on 19 February 2021, at 13:38.

This performance was mainly due to sliding shuttering. Before the bridge was built it took over 3 hours to traverse the Tarn River valley! They also applied the launching technology. In high winds, they continuously monitor the reactions of the Viaduct to extreme conditions.

The exterior envelope of the stays is itself coated along its entire length with a double helical weatherstrip. The A75 now provides a direct, high-speed route from Paris to the Mediterranean coast and on to Barcelona. [citation needed], In March 2002, the pylons emerged from the ground. When the details were eventually finalised, the whole design was approved in late 1998. Satellite image of the route before construction of Millau Viaduct #3 Millau Viaduct was designed by Norman Foster and Michel Virlogeux. Millau viaduct 1. 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.

The bridge, made out of steel and concrete, gives the viaduct a strong fine structure with only 7 points along the construction supporting it and 1,500 tonnes of live wire covering the surface of the bridge. [23], The electrical installations of the viaduct are large in proportion to the size of the bridge. [citation needed], The steel road deck, and the hydraulic action of the road deck were designed by the Walloon engineering firm Greisch from Liège, Belgium,[16] also an information and communication technologies (ICT) company of the Walloon Region. By July 1993, seventeen structural engineers and thirty-eight architects applied as candidates for the preliminary studies. However, if the concession yields high revenues, the French government can assume control of the bridge as early as 2044. The stays connecting the masts and the deck were then installed, and the bridge was tensioned overall, and weight tested. Viaduc de Millau: Some construction!
