Daiichi Daido-gawa Bridge

The Daiichi Daido-gawa Bridge is a concrete span carrying traffic across the river in Koka, with a straightforward design characteristic of post-war Japanese engineering. The beam structure and modest dimensions create a direct, no-frills crossing, with visible reinforcement details and a surface bearing marks of long service.

The bridge was constructed in 1954 as part of Japan's infrastructure rebuilding following wartime destruction. It represents the era when the nation prioritized practical structures needed for economic recovery and restoring basic connectivity.

This structure functions as everyday infrastructure rather than as a monument on display. Its form reflects the practical approach to building that Japan adopted during post-war recovery, and anyone crossing it sees engineering designed for utility rather than ornament.

The bridge is accessible by car or on foot from central Koka, with straightforward approach routes. River conditions below can shift with seasons, but the structure remains safe and open to crossing year-round.

Unlike many Japanese historical bridges that are restricted from use or undergo major restoration, this one continues to carry regular traffic and has been updated multiple times since opening. Its status permits practical modifications to safety and drainage systems while preserving the fundamental structure and original character.
