虹澗橋

Nijikanbashi is a steel bridge in Oita Prefecture that connects two sides of the landscape with a rigid frame construction. The structure spans the valley with a functional steel design that shapes the local terrain.

The bridge was built in the late 1970s as part of Kyushu's infrastructure development during rapid regional growth. Its construction improved transportation connections across the valley.

The bridge serves as a meeting point for local residents who gather near its supports to observe seasonal changes in the surrounding environment.

The bridge is accessible by regional bus and private vehicle, with stops near both ends of the span. Visit during clear weather when views of the surrounding valley are best.

The bridge displays different color tones in sunrise and sunset light, which inspired its name. These visual changes make visiting at different times of day particularly rewarding.
