the Great Seto Bridge

Breathtaking beauty at the world’s longest two-tier bridge

With its lofty white steel towers and gentle curves spanning across five islands, the Great Seto Bridge combines Japan’s natural seaside elegance and technological eminence. Amazingly, the bridge stretches 13.1 kilometers across the Seto Inland Sea between Kojima in Okayama Prefecture and Sakaide in Kagawa Prefecture. In fact, this amazing architectural feat is the world’s longest two-tier bridge. 

Finishing in 1988, the structure took 10 years to complete. What distinguishes this masterpiece from other bridges is its employment of three forms of structural technology–suspension, cable-stayed and truss bridge. As a result, great variety is reflected in the bridge segments. In addition, three unique designs across this seaside landmark well make the journey worth your time.

There’s no better way to enjoy viewing this structural marvel and its surrounding scenery than by crossing it. Delight in the fresh seaside breeze by taking a refreshing 20-min daytime drive across its span (tolls starting at 3,300 yen). Or hop on the JR Seto-ohashi train line (510 yen) that runs on the lower level of the bridge–the. In fact, it is the only railway line connecting Honshu and Shikoku islands.
