After billions of dollars in construction works, the Seto Inland Sea is now crossed by no less than three stupendously huge bridges. From east to west:
- Akashi Kaikyo Bridge, with the longest suspended span in the world, between Akashi (off Kobe, Honshu) and Awaji

- Shimanami Kaido, from Hiroshima (Honshu) to Ehime (Shikoku)
