The Millau Viaduct (French: le Viaduc de Millau) is a large cable-stayed road-bridge that spans the valley of the River Tarn near Millau in southern France. Designed by the structural engineer Michel Virlogeux and British architect Norman Foster, it is the tallest vehicular bridge in the world, with one mast's summit at 343 metres (1,125 ft) — slightly taller than the Eiffel Tower and only 38 m (125 ft) shorter than the Empire State Building.
