Niigata, Japan's Bridges; Hasaki Bridges on the Hokuriki Expressway (1)

August 2007 (37.315 Degrees, 138.437 Degrees) Hasaki Bridges

The Hasaki Bridges go between two tunnels on the Hokuriki Expressway. They are parallel five-span concrete ‘I’ girder bridges on seat-type abutments and tall pier walls.  The three northern spans are continuous over steel bearings with an expansion joint at the end of the third span. The piers are on piles except where there is rock near the surface.  The bridges are just north of the Yoneyama tunnels (shown in the photo), which were damaged by the 2007 Kashiwazaki Earthquake. The bridges were also damaged. We went under the bridges to look at the bottom of the piers but the undergrowth was so thick we couldn’t get close to them. We'll take another look at these bridges tomorrow.
