Great Seto Bridge

The Great Seto Bridge is a two-tier bridge and viaduct complex in Japan – rail and highway – completed in 1988 and linking the islands of Honshū (Okayama Prefecture) and Shikoku (Kagawa Prefecture) across the Inland Sea of Seto leaning on a series of five small islands.

It is the first part of the Honshū-Shikoku Bridge Project, which also includes the Great Akashi Kaikyō Bridge, the largest suspension bridge in the world.

The Seto-Ōhashi is made up of three suspension bridges and two cable-stayed bridges, two viaducts or elevated roads, as well as a traditional steel bridge.

The total length is 13.1 km and the average height of the pillars is 200 meters.
It took 10 years to complete the construction.


The bridge has two levels.
The Seto-Chūō Expressway runs on the upper level, and the lower level has two tracks of the Japan Railways Seto-Ōhashi Line.
These two tracks occupy only half the level, the other half is reserved for the future Shinkansen.

To cross the bridge you have to pay a toll of 3,500 yen each way (approx. 22 Euro).

Compared to the Uno-Takamatsu ferry, which takes an hour, the drive over the bridge is only 15 minutes.
The bridge is earthquake and typhoon proof.
