The Strongest Bridge: Akashi Kaikyo

While talking about bridges, how can we forget Akashi Kaikyo Bridge. It is known as the strongest and longest suspension bridge in the world with a length of 12,831 feet. This bridge is also called ‘Pearl Bridge’. Akashi Kaikyo Bridge is located in Japan and serves as a link between the city of Kobe and Iwaya. This four miles wide bridge has six lanes. The construction of this bridge started in 1988 and took 10 years to complete.


Quick Facts: –

  • Approximately two million workers worked for 10 years to construct this bridge. This construction used 180,000 tonnes of steel and 1.4 million cubic meters of concrete.
  • The bridge holds three different records: – the strongest, longest and most expensive suspension bridge in the world.
  • Akashi Kaikyo Bridge is in a typhoon region where winds can reach speeds of 290 kmph.
  • The total length of cables used in the construction of the bridge is about 300,000 kilometers.
  • It has been designed to withstand earthquakes and harsh sea condition. The Kobe earthquake in January 1995 is the best example showing the strength of this bridge. That earthquake measured 6.9 on the Richter Scale.
  • It was under construction when this earthquake struck the country.
  • The total cost of the Akashi Kaikyo Bridge was $4.3 billion.
  • On average, about 25,000 cars pass on it every day.
  • Now it has become a tourist attraction in Japan as two amazing parks named as Maiko and Asagiri have been built near the bridge.
  • It was a challenge for Japanese engineers to build a bridge like this because Japan is located in the Ring of Fire. The chances of earthquakes and volcanic eruptions are very high.
