It was declared a National Treasure in 1922. The bridge is composed of five sequential wooden arch bridges on four stone piers as well as two of wooden piers on the dry riverbed where the bridge begins and ends. Each of the three middle spans is 35.1 meters long, while the two end spans are 34.8 meters for a total length of about 175 meters with a width of 5 meters.
