Great Seto Bridge
The Great Seto Bridge is a two-level bridge and viaduct complex – rail and road – completed in 1988, linking the islands of Honshū (Okayama Prefecture) and Shikoku (Kagawa Prefecture) across the Seto Inland Sea on a series of five small islands in Japan. It is part of the largest suspension bridge in the world, and the longest 2-tier bridge in the world.
The total length is 13.1 km and the average height of the pillars is 200 meters. It took 10 years to complete construction. To cross the bridge, a toll of 3,500 yen per way (approx. 30 USD) must be paid. Compared to the one-hour ferry between Uno and Takamatsu, the drive across the bridge takes only 15 minutes. The bridge is earthquake and typhoon proof.
