The Akashi Kaikyo bridge, located between the city of Kobe and Awaji Island, is the longest suspension bridge in in world at a length of 3910m long. The Akashi straits are one of the busiest shipping lanes in the world with over 1000 ships passing through daily so the idea to create a bridge gained in popularity. The decision to construct a bridge between the mainland and Shikoku became urgent after a disaster in 1955, when a ferry collided with another sinking and killing over one hundred children and sixty eight adults. Construction of the bridge began in 1988.
Now the Akashi Kaikyo Bridge is considered one of Japans greatest engineering feats. The construction of the bridge took two million workers 10 years to construct with 181,000 tonnes of steel and 1.4 million cubic metres of concrete. In the case of Akashi Kaikyo the suspension bridge technology was pushed to the very limits.
If you are thinking of taking a look at the bridge there is a park at the base of the bridge called Maiko park on the mainland side where you can get some great shots of the bridge. There is also a marine Promenade that is built in the girder of the bridge that you can walk in and also a few places in and around the park to have a look at. The bridge also becomes illuminated at night which is quite a sight to see.
You can take a train to the bridge via the JR Kobe line to Maiko station. Maiko station is at the very base of the bridge so you’ll have no trouble getting there.
