Commissioned in 2004, the Millau viaduct (Aveyron), on the A75 motorway linking Clermont-Ferrand and Béziers, is a record-breaking bridge, not only in terms of sheer dimensions - 343 m high for the highest pier and 2,460 m long - but also because it required fourteen years’ preparation work and three years’ construction work... with the mobilisation of all Eiffage’s divisions, i.e. a peak construction workforce of nearly 600 master craftsmen.
Designed by French engineer Michel Virlogeux and British architect Lord Norman Foster, the Millau Viaduct blends delicately into the landscape. Its thin piles, its slender lines, its slim deck, and its slight curve are not only an aesthetic achievement, but also a technical wonder. Thirteen years after its opening, the viaduct has already been used by more than 50 million vehicles.”
This viaduct, which is the most breathtaking section of the A75 motorway linking Clermont-Ferrand with Béziers, reaches a height of 343 metres and is 2,460 metres long.
Designed by French engineer and British architect Lord Norman Foster, it is made up of two slim pylons and a light deck and touches the valley below at only seven points, although its construction required 85,000 m3 of concrete and 36,000 tonnes of structural steel.
