Viaduc de Millau

The Millau Viaduct (French: le Viaduc de Millau, IPA: [vjadyk də mijo]; Occitan: lo Viaducte de Milhau) is a cable-stayed road-bridge that spans the valley of the river Tarn near Millau in southern France. Designed by the British architect Norman Foster and French structural engineer Michel Virlogeux, it is the tallest bridge in the world, with one mast's summit at 343.0 metres (1,125 ft). It is the 12th highest bridge in the world, at 270 metres (890 ft) high below the road deck. The viaduct is part of the A75-A71 autoroute axis from Paris to Montpellier. Construction cost was approximately €400 million. It was formally dedicated on 14 December 2004, inaugurated the day after and opened to traffic two days later. The bridge received the 2006 IABSE Outstanding Structure Award.
