“The Seto-Ohashi Bridge, is a series of double deck bridges connecting Okayama and Kagawa prefectures in Japan across a series of five small islands in the Seto Inland Sea. Built over the period 1978–1988, it is one of the three routes of the Honshū-Shikoku Bridge Project connecting Honshū and Shikoku islands. At 13.1 km long, it ranks as the world’s longest two-tiered bridge system.
Crossing the bridge takes about 20 minutes by car or train. The ferry crossing before the bridge was built took about an hour. The non-discounted toll from Kojima, Kurashiki (Okayama Prefecture on the Honshū side) to Sakaide (Kagawa Prefecture on the Shikoku side) is ¥3,500, and vice-versa.” (Wikipedia)
Japan has many good bridges like the Rainbow Bridge in Odaiba in Tokyo and the Akashi-Kaikyo Bridge connecting Kobe to Awaki Island, besides many other famous bridges around Japan. However, since Seto Bridge is the longest two-tiered bridge, it’s the most joyful one to drive on. I’ve never drove on it or been to that region before but imagining driving for 20 min over a suspended bridge passing through a number of small islands is awesome! Moreover, I’ve always wanted to visit Shikoku island, taking the Seto Bridge from Honshu would make the road trip even more fun.
