Shimotsui-Seto Bridge

The Shimotsui-Seto Bridge spans 1,447 meters across the Seto Inland Sea, reaching a height of 149 meters with a main span of 940 meters.

Construction of this major infrastructure project began in 1978 and continued until its official opening in 1988, connecting the islands of Honshu and Shikoku.

The bridge design incorporates elements that preserve the natural landscape of the Seto Inland Sea National Park, including a specialized tunnel anchorage on the Honshu side.

The double-deck structure accommodates both railway tracks and vehicle lanes, providing essential transportation links between Kurashiki and Sakaide cities.

The Washuzan Tunnel at the northern end features a four-eye design with separate passages for highway and railway traffic, demonstrating advanced engineering solutions.
