About this converter
Suspension bridge main spans run from 1,377 to 1,991 meters here, which makes every crossing easy to compare. Tsing Ma Bridge spans 1,377 meters, while Akashi Kaikyo spans 1,991. That means one Akashi equals 1.4 Tsing Mas. Every figure on this page is a main suspended span between towers from Structurae pages and bridge authority data, not total bridge length. Akashi Kaikyo has held the world lead since 1998. Four of the ten spans cross the Yangtze River in China. Humber Bridge opened first in 1981 and held the record about 17 years.
How to use it
Pick two bridges and a unit in the top row. The three boxes below stay linked: one holds a count of the first span, one the matching count of the second, one the distance in the chosen unit. Change any box and the other two update. Try 1 Akashi Kaikyo against Tsing Ma to feel the longest versus shortest gap, or stack Humber spans against Great Belt.
