Kurushima-Kaikyo Bridge (Imabari City, Ehime Prefecture)
Overview (history, characteristics, attractions)
The Kurushima-Kaikyo Bridge is a series of continuous suspension bridges spanning the Kurushima Strait in the Seto Inland Sea, located in Imabari City, Ehime Prefecture. Opened in 1999 as part of the Nishi-Seto Expressway (Shimanami Kaido), it is an important transportation route connecting Shikoku (Imabari) with the surrounding islands. The structure of three continuous suspension bridges is rare worldwide, and is known as "one of the world's largest continuous suspension bridge structures."
One of its features is that it is not just a roadway, but also has the Shimanami Kaido cycling route (bicycle and pedestrian path), and its greatest appeal is being able to view the beauty of the Seto Inland Sea's many islands and strong currents up close from the bridge. The silhouette of the bridge and the sea, which changes appearance depending on the weather and time of day, is also popular with photography enthusiasts.
Highlights
- The bridge's magnificent structural beauty: The powerful form of the three consecutive suspension bridges is a sight to behold both from a distance and up close.
- Tidal currents and seascapes: The tides in the Kurushima Strait are fast, and whirlpools and tide lines can sometimes be seen. The beauty of the islands on a clear day and their silhouettes at dusk are particularly beautiful.
- Cycling: As part of the Shimanami Kaido, you can cycle across the bridge, so you can enjoy the scenery while cycling across it (bicycle rental locations are available at Sunrise Itoyama and other locations).
- Viewpoint: Sunrise Itoyama (Itoyama Park) on the Imabari side has an observation deck and rest area where you can get a close-up view of the bridge.
- Night view: The bridge is sometimes lit up, making it a picturesque sight at night (the days when it is lit up may vary).
