Facts

  • The deck area is about 65,000 square meters.
  • The deck has a slope of 3% in the north-south direction.
  • The Millau Viaduct is a cable-stayed suspension bridge hung from a single, central line of 154 cable-stays attached to seven pylons each atop a pier.
  • If placed side by side, the bridge would comfortably overshadow another of France's iconic tall structures, the Tour Eiffel.
  • The bridge has been designed to last for at least 120 years.
  • The deck weighs around 36,000 tons.
  • The deck was slowly inched out hydraulically over the piers in two sections from the north and south, a process which took 14 months.
  • Viaduc de Millau was aligned with the use of Global Positioning Satellites (GPS).
  • The bridge has four lanes of traffic and two side walkways and is around 32 metres (105 feet) wide and 2.46 km long.
  • Ground for the viaduct was broken in October 2001.
  • The bridge spans the Tarn valley.
  • The bridge was built to reduce traffic bottlenecks in Millau and link Spanish and French motorway networks.
  • The piers vary in height from 75 metres (246 feet) to 245 metres (804 feet) and are separated by a distance of 342 metres (1,122 feet).
  • Viaduc de Millau is the world's tallest bridge, has the world's tallest piers and also features the world's highest road deck at 886 feet above the ground.
  • The bridge was constructed with 85,000 cubic metres of concrete (206,000 tons) supplied by an on-site concrete manufacturing plant.
  • The concrete was reinforced with around 15,000 metric tons of rebar (4,000 km).
  • A slight curve in the bridge reduces the sensation of floating that a straight span would otherwise induce.
  • Winner of 2006 IABSE Outstanding Structure Award.
  • French President Jacques Chirac inaugurated the bridge on December 14, 2004, that is three years to the day from the laying of the first stone. It opened to traffic two days later.
  • Final cost of the bridge was 400 million Euros, including 80 million for the toll barrier.
  • Each pier splits 90 meters under the deck to facilitate the structure flexibility.
