Viaduc de Millau

The Millau Vidaduct is the world's tallest bridge. It was designed by Sir Norman Foster, of Britain and is located near Millau, France. It spans the valley through which the River Tarn flows, connecting two existing sections of highway.

The Viaduct is multi-span, cable-stayed, with seven evenly spaced concrete piers from which the deck is suspended by cable stay fans, giving it a delicate appearance and elegant silhouette, as well an economy in use of material. Its road deck is steel, allowing the number of stay cables to be reduced, with a gentle plan curve. Slender piers ending 109 yards below the deck have evolving geometrical profiles, giving an eye of the needle effect. The facetted sectional form also disguises their size, all of which was critical to allow the design to blend into the landscape.
