If you are cycling or walking the Shimanami Kaido, the road that connects Onomichi in Hiroshima with Imabari on Shikoku, then the first bridge you cross is the Innoshima Bridge connecting Mukaijima Island with Innoshima island.
When it was built in 1983 it was the longest suspension bridge in Asia. The total length is 1,339 meters, and the main span is 770 meters.
All the bridges of the Shimanami Kaido can be used by pedestrians and cyclists, and on the Innoshima Bridge they are carried below the expressway carrying cars.
Though the views are a little obscured by the chain link fence, at around 40 meters above the water the views are still great.
