The Millau Viaduct is a large cable-stayed road bridge that spans the valley of the river Tarn near Millau in the Massif Central mountain range in southern France. Designed by the structural engineer Michel Virlogeux and architect Norman Foster, at 2.4km long, and 270m above the river at its highest point, it is the tallest vehicular bridge in the world.An interesting fact is that the Millau Viaduct is not straight. The bridge was built with a slight curve that has a radius of 20km. Such a high straight road could induce a sensation of floating for drivers, which is remedied by the curve.
Supported by two anchorage points at either side and seven piers supporting the carriageway, the bridge will soar across the Tarn valley at a central height of 245m. The project has consumed 19,000 tons of concrete-reinforcing steel, 5,000 tons of reinforcing steel for cables and 85,000 cubic meters of concrete - enough to fill London’s Albert Hall.
