Currently the world’s tallest bridge, the Millau Viaduct in France has masts that summit at 1125-feet above the base of the structure, which spans 8070-feet in length. It’s a part of the A75-A71 autoroute axis from Paris to Montpellier. Continue reading for a video, more pictures, and additional information.
The bridge’s construction cost up to €394 million, with a toll plaza 6 km (3.7 mi) north of the viaduct costing an additional €20 million. The builders, Eiffage, financed the construction in return for a concession to collect the tolls for 75 years, until 2080. However, if the concession is very profitable, the French government can assume control of the bridge in 2044.
The project required about 127,000 cubic metres (166,000 cu yd) of concrete, 19,000 tonnes (21,000 short tons) of steel for the reinforced concrete and 5,000 tonnes (5,500 short tons) of pre-stressed steel for the cables and shrouds. The builder claims that the lifetime of the bridge will be at least 120 years.
