Photographer's Note

The biggest viaduct in the world is opened today!
This is a structure 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.
