This image was a lucky capture driving my car over the Wailuku Singing Bridge or the Humming Bridge bordering Hilo Bay and north of Hilo town proper. The steel stringer bridge was built in 1950 replacing a 3 span railroad bed at the same location. That bridge was a casualty of the devastating 1946 tidal wave in Hilo. of The bridge spans the Wailuku River on the Hawaii Belt Road on Highway 19, in Wainaku, Hawaii County on the island of Hawaii, USA.
