The bridge linking Shikoku and other islands with Honshu, surrounded by the islands of the Seto Inland Sea.
The Nishi-Seto Expressway, also known as the Seto-uchi Shimanami-Kaido (highway above sea), was opened to traffic on 1 May 1999. The bridge connects Onomichi City in Hiroshima and Imabari City in Ehime, as well as six islands (namely Mukai-shima, Inno-shima, Ikuchi-jima, Omi-shima, Hakata-jima, and O-shima islands) within the Geiyo Islands situated near the center of the Seto Inland Sea. The completion of the Shimanami-Kaido has made Ehime more easily accessible from Honshu and driving through the Geiyo Islands possible. The highway also allows passage by bicycle and on foot.
With unique island-to-island bridges, such as the Tatara-ohashi Bridge (the longest askew-arched bridge in the world) and the Kurushima-kaikyo-ohashi Bridge (a triple suspension-type grand bridge), the Shimanami-Kaido provides brand-new scenery in harmony with insular nature. The best viewing spots to overlook the bridges over the Seto Inland Sea and various islands are the Hanaguri Seto observation platform on Omi-shima Island and Mt. Kiro-san on O-shima Island. Thanks to the mild climate, there are many flower viewing spots, such as the Yoshiumi Rose Garden (where you can see various kinds of roses collected from all parts of the world), Citrus Park Setoda (which boasts citrus plants as the main attraction), as well as the Inno-shima Flower Center.
Also on the Shimanami-Kaido, there are places such as the Michi-no-eki (roadside station) Yoshiumi Ikiiki-kan and the Marine Oasis Hakata that sell local products as well as local specialty centers, all for your shopping pleasure.
