14-432: A bridge is the maximum vertical drop distance between the bridge deck (the road, rail or other transport bed of a bridge) and the ground or water surface beneath the bridge span. Deck height is different from structural height , which is a measure of the maximum vertical distance from the uppermost part of a bridge, such as the top of a bridge tower to the lowermost exposed part of the bridge, where its piers emerge from
21-536: Is situated near the valley floor, which gives the viaduct a structural height of 343 m (1,125 ft), and a deck height of 270 m (890 ft) above the valley floor. The Millau Viaduct is (as of 8 February 2020) the tallest bridge, but only the thirtieth highest bridge in the world. The ranking of the highest bridges in the world, currently open for use.

The bridge's two towers, built on the rims of the gorge, are 269 m (883 ft) tall, but due to the depth of the river gorge between the towers, the deck height of the Duge Bridge is 565 m (1,854 ft). The Millau Viaduct is a cable-stayed bridge that is both tall (in structural height) and high (in deck height). The tallest Millau Viaduct tower

The bridge was built with the assistance of a $ 208 million loan from the Asian Development Bank ; the total project cost was $ 610 million, which included 64 kilometres (40 mi) of expressway construction (two thirds of which comprised bridge and tunnel) and upgrades to 129 kilometres (80 mi) of local roads.

49-409: The surface of the ground or water. The difference between tall and high bridges can be explained in part because some of the highest bridges span the deepest part of their valley or gorge supported from above, with their ground supports built on relatively high terrain only; some of the tallest bridges have support structures on the lowest part of the valley floor.
