Seto-ohashi Bridge is a collective term for the
six bridges that connect Kojima in Okayama
Prefecture on Honshu and Sakaide of Kagawa
Prefecture on Shikoku, spanning five islands,
namely Hitsuishi-jima Island, Iwaguro-jima Island,
Wasa-jima Island, Yo-shima Island, and Mitsugo-
jima Island in the Seto Inland Sea. The bridges
took 40 years and a tremendous amount of money to
build. The bridge is more than 13 kilometers long,
and has become a major sightseeing spot. The upper
level is for the Seto-Chuo Expressway, and the JR
Seto-ohashi Line and a pass road share the lower
level. The bridge is crowded with not only those
who need to cross it but also many tourists.
The six bridges consist of three suspension bridges, two oblique suspension bridges, and one truss bridge. They are the essence of all available bridge-building technologies, and are beautiful. The silhouettes glowing in the setting sun are particularly beautiful. The bridges are illuminated after sunset.
You can see the entire bridges from the top of Mt. Washu-zan that juts out at the southwestern edge of the Kojima-hanto Peninsula. Pleasure boats cruise from Kojima Sightseeing Port and Yo-shima Island to provide a view from the sea. It is a pleasure to compare the different angles for each course and boat.
