What makes the Akashi Kaikyo Bridge so strong?
The two strong girder systems enable the structure of the bridge to withstand against typhoons, earthquakes and harsh sea currents. The height of each supporting pylon is 282.8m (928ft). In a day, the bridge can expand up to two metres (seven feet) due to heat.
What is special about Akashi Kaikyo Bridge?
The record-breaking, and beautiful, Akashi Kaikyo Bridge in Japan is one of the world’s longest and tallest. The Akashi Kaikyo Bridge in Japan is an engineering marvel and record-breaker. This impressive bridge is not only very long, but it has been designed to withstand earthquakes up to 8.5 on the Richter scale!
How much weight can the Akashi Kaikyo Bridge hold?
120,000t.
The structure also has to support the vertical force of 120,000t. Although the central span length of the Bridge is about twice as long as those of previous suspension bridges, the girder of 1,991m long had to be erected.
How long did it take to build the Akashi Kaikyo Bridge?
10 years
It is part of the ongoing Honshu- Shikoku Bridge Authority (HSBA) project to link the islands of Honshu, Awaji and Shikoku. After 10 years of construction and a total cost of $3.6 billion, Akashi Kaikyo Bridge opened on April 5, 1998, measuring 3,911 m long with a center span of 1,991 m.
How old is the Akashi Kaikyo Bridge?

Akashi-Kaikyo Bridge/Total length
What is the longest bridge in the world over water?
the Lake Pontchartrain Causeway
The world’s longest continuous bridge over water is the Lake Pontchartrain Causeway in southern Louisiana. The causeway is actually two parallel bridges, with the longer of the two measuring close to 24 miles (39 km), according to Encyclopaedia Britannica.
How does the Akashi Kaikyo withstand an earthquake?
So when the wind blows the bridge in one direction, the TMDs sway in the opposite direction, effectively “balancing” the bridge and canceling out the sway. With this design, the Akashi Kaikyo can handle 180-mile-per-hour winds, and it can withstand an earthquake with a magnitude of up to 8.5 on the Richter scale!
What is the history of Akashi-Kaikyo Bridge?
Introduction of Akashi-Kaikyo Bridge. Akashi-Kaikyo Bridge is the longest span bridge in the world, located in Akashi Strait between Kobe and Awaji Island in Hyogo Pref. The total and central span lengths are 3,911m and 1991m respectively. The Bridge was constructed as one of Honshu-Shikoku Bridge project, which is one of
Why is there no bridge in the Akashi Strait?
The Akashi Strait is a busy shipping port, so engineers had to design a bridge that would not block shipping traffic. They also had to consider the weather. Japan experiences some of the worst weathers on the planet.
What type of earthquake can the bridge withstand?
The Bridge was designed to resist both strong wind, 80m/sec, and great earthquakes such as an inter-plate type earthquake which predicts to occur around Pacific Ocean and an earthquake directly above its epicenter like the Southern Hyogo Prefecture Earthquake in 1995.
