This list of highest bridges includes bridges with a deck height of at least . The of 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, 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 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.
For example, (as of 8 February 2020) the Duge Bridge is the highest bridge in the world, but only the tenth tallest. This bridge spans a deep river gorge. The bridge's two towers, built on the rims of the gorge, are tall, but due to the depth of the river gorge between the towers, the deck height of the Duge Bridge is .
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 is situated near the valley floor, which gives the viaduct a structural height of, and a deck height of 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.
