Millau Viaduct: The World’s Highest Bridge
The Millau Viaduct is part of the new E11 expressway connecting Paris and Barcelona and features the highest bridge piers ever constructed.
The tallest pier\’s summit is at 341 metres (1,118 ft)—slightly higher than the Eiffel Tower and only 40 m (132 ft) shorter than the Empire State Building.
It is 2460 m long, consisting of eight cable-stayed bays, the longest of which is 342 m. The 2-lane dual carriageway suspensed almost 270 m above the Tarn will follow a wide curve with a slight gradient of 3 % to improve visibility on the structure and protect road-users.
Lateral screening is designed to reduce wind effects. The seven bridge piers will be built of reinforced concrete, in the form of pyramids splitting into reversed V-shapes ; thereby providing anchorages for the splayed cables.
The tallest pier unit will reach a height of 340 m, as tall as the Eiffel Tower.
About 127 000 m3 of concrete, 19 000 tons of reinforcing steel and 5 000 tons of prestressed steel (cables and stays) will be needed to build the structure.
