The Millau Viaduct
The Millau Viaduct (Aveyron), which required €400 million of investment, breaks all the records.
It took 3 years of construction (2001-2004), the support of all the Eiffage divisions and the dedication of some 600 workers at the height of the works, to achieve its construction.
The bridge, which is the most spectacular section of the A75 Clermont-Ferrand-Béziers motorway, reaches a height of 343 metres and is 2,460 metres long. Designed by French engineer Michel Virlogeux and British architect Lord Norman Foster, it is made up of thin sleek pylons and a light deck, and grazes the valley at just seven points of contact, although its construction required some 85,000 m3 of concrete and 36,000 tons of structural steel.
Each year, nearly 4.8 million vehicles pass through the tolls, 10% of which are trucks. Since it was opened on 16 December 2004, the viaduct has been used by over 45 million vehicles. And an estimated 50 million vehicles will have crossed over by the end of summer 2015.
The concession (78 years in total including three years of construction work and 75 years of operating) runs until 2079.
