The Akashi Kaiyko bridge is not only very long, but also tall, its two towers, 282 meters high, are higher than any other bridge towers.
Akashi Strait is a very busy port because architects had to design a bridge so that it would not block traffic. In addition, they had to take into account the changing weather, strong winds, heavy rainfall, hurricanes, tsunamis and earthquakes. Among other things, they built towers with lattice bonds, which stiffened the structure and allowed the wind to flow between the bars.
The bridge is able to withstand a wind pressure of 180 miles per hour, and an earthquake magnitude 8.5 on the Richter scale.
The length of all cables used to build the bridge is 300,000 kilometers, it would be enough for a circle around the Earth seven and a half times.
The bridge has three records, it is the longest, highest and most expensive suspension bridge in the world.
The bridge originally had a length of 12,825 feet, but on January 17, 1995, a great earthquake stretched it and now it is 3 feet longer.
