Shimotsui-Seto Bridge

The Shimotsui-Seto Bridge is a double-deck structure spanning the Seto Inland Sea, with railway tracks on the lower level and vehicle lanes on the upper deck. The main cable supports rise high above the water, creating a dramatic profile visible from many vantage points in the region.

This bridge was conceived in the 1970s to address growing transportation demands between Honshu and Shikoku. Its completion in the late 1980s marked a major milestone in Japan's infrastructure development and improved connectivity across the island chain.

This bridge is part of the Seto Ohashi Line, a vital link that carries thousands of commuters daily between the islands. It has become woven into the everyday life of residents in both cities, shaping how people move and connect across the waters.

You can experience the bridge by riding across it on a train or driving a car, as both transit types use it regularly. For the best views of the entire structure, visit observation points on either shore during daylight hours.

The bridge features a hidden tunnel section at the Honshu end that conceals the main cable anchors underground. This clever engineering choice keeps the landscape less disrupted and shows how designers tried to minimize the structure's impact on the surrounding land.
