submersible bridge 潜水橋

氾濫を繰り返す富田川では、洪水で破壊されない橋を架ける必要があり、らんかんなどの水の抵抗を受けるもののない潜水橋が架けられました。四国の四万十川の潜水橋を参考にしてつくられたといわれています。

In the Tonda River, which is repeatedly flooded, it was necessary to build a bridge that would not be destroyed by the flood, and a submersible bridge that was not subject to water resistance such as lanterns was built. It is said that it was made with reference to the submersible bridge of the Shimanto River in Shikoku.
