Sango Bridge, Steel bridge in Kitakami City, Japan

Sango Bridge is a steel bridge over the Kitakami River in Kitakami, Iwate Prefecture, on the old route of National Route 107, now a city road. It is a deck cantilever truss (Gerber truss) bridge with a total steel weight of 390.0 tonnes, and a steel cable-stayed footbridge was added alongside it in 1971.

The first bridge was a wooden structure financed in 1908 by Tokujiro Takachita of Tachibana village and run by a cooperative that charged a toll to cross. Repeatedly washed away by floods of the Kitakami River, it was replaced in 1933 by the present steel bridge. In 1971 a steel cable-stayed footbridge was attached alongside.

The bridge is named after Sango-dake, a peak on the northern ridge of Mount Kunimi. Until the current steel bridge opened in 1933, crossing the Kitakami River here required paying a toll to the cooperative that ran the first wooden bridge, built in 1908 with funds from Takachita Tokujiro of Tachibana Village.

From Kitakami Station on the Tohoku Main Line, take the Onimaru-go Kuchinai line bus and get off at the Sango Bridge stop; the bridge is about a 10-minute walk from there. The bridge now carries a city road, having been downgraded from National Route 107 after the Hidagami Bridge opened.

The 1933 truss is a Gerber (cantilever) bridge carrying 390.0 tonnes of steel, built for about 200,000 yen at the time. In 1971 a steel cable-stayed footbridge was hung alongside it. The name comes from Mount Sango on the northern ridge of Mount Kunimi, not from coral.
