Niigata, Japan's Bridges: Heisei O'Hashi across the Sabaishi River

August 2007 (N37.3888° E138.5767°) Heisei O'Hashi

On the other side of the island formed by the meandering Sabaishi River is the Heisei O'Hashi, which means the 'big' Heisei Bridge. It is bigger than the Heisei Bridge on the other side of the island. 

This is a continuous, two-span, haunched concrete box girder bridge supported on seat-type abutments and a big caisson.  During the earthquake, the north bridge embankment settled about 400 cm.  There were also signs that the bridge underwent shaking and pounding. 

Although the abutments were on piles, the bearings were distorted, indicating that the abutments had been pushed toward the river.
