Railway bridges can be ranked based on either their structural height or deck height. A bridge’s structural height is defined as the full vertical distance between the highest point of the bridge and lowest visible point of the bridge, where the pillars emerge from the ground whereas the height of the deck is measured as the maximum length of the vertical drop starting from the deck of the bridge to the ground below the span of the bridge. The ranking of the tallest and the highest bridges may differ depending on the choice of a ranking measure. There are many tall bridges in the world, but China has the highest concentration of the tallest railway bridges.
