List of tallest bridges
This list of tallest bridges includes bridges with a structural height of at least. The of a bridge is 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, towers, or mast pylons emerge from the surface of the ground or water. Structural height is different from, which measures the maximum vertical distance between the bridge deck and the ground or water surface beneath the bridge span. A separate list of highest bridges ranks bridges by deck height.
There may be differences between the various heights given, as the heights do not always include the same elements depending on the information provided by the design offices. In the lower part, the level may be the water level or the highest water level, the lower part of the foundation header, or the upper part of the tower base. In the upper part, the level may be the concrete or steel structure of the tower, the axis or IP of the main cable, or the highest structural or architectural elevation. The 1915 Çanakkale Bridge gains with its tower-top ornament.
Structural height and deck height
The difference between tall and high bridges can be explained in part because some of the highest bridges are built across deep valleys or gorges. For example, the Huajiang Canyon Bridge is the highest bridge in the world, but it is not in the top 20 tallest bridges. This bridge spans a deep river gorge. The bridge's two towers, built on either rim of the gorge, are tall, but due to the depth of the river gorge, the deck height of the Huajiang Canyon Bridge is.The Millau Viaduct is a cable-stayed bridge that is both tall and high. 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.
