Why Famous for Great Seto Bridge, Kurashiki?
The Great Seto Bridge is famous for several reasons. First and foremost, it’s a marvel of modern engineering, featuring six individual bridges—two suspension, three cable-stayed, and one truss bridge—constructed over nine years and completed in 1988. It carries a highway on the upper deck and a railway on the lower deck, something rarely seen at such scale. The bridge is renowned for its panoramic views, especially during sunset, and is often illuminated at night, making it a favorite among photographers and tourists.
Additionally, it symbolizes the strong link between Honshu and Shikoku, significantly contributing to economic and cultural exchange. The bridge is also a subject of study for engineering and architecture students across the world.
History and Architecture
The Great Seto Bridge was proposed after World War II as a way to improve access between Japan’s main islands. Construction officially began in 1978 and involved more than 700,000 workers. The design had to withstand typhoons, earthquakes, and heavy shipping traffic. As a result, the bridge was built with cutting-edge seismic and wind-resistant technologies.
The structure includes steel and concrete elements with special vibration-dampening systems. Its total length is 13.1 kilometers, and it rests on multiple small islands in the Seto Inland Sea. The architectural design blends strength with elegance, complementing the natural beauty of the surrounding environment.
