Sada Chinkabashi Bridge
佐田沈下橋
The longest submersible bridge (chinkabashi) on the lowest reach of the Shimanto River, about 291 m long. Its low, railing-free deck is the emblem of the “last clear stream.”
Submersible bridges have no railings and are designed to sink under floodwater so they aren't swept away. The Shimanto River and its tributaries have more than 40 of them. The Sada Chinkabashi Bridge, also known as Imanari Bridge, is about 291.6 m long. It is the longest on the main stream and the furthest downstream, and it is only about 8 km from central Nakamura, which makes it the easiest to reach. The deck is narrow, and cars can pass in one direction only, so give way to pedestrians and cyclists. The bridge is closed when the water rises. Nearby are boat rental and boarding points for traditional roofed boats (yakata-bune).
