This bridge was constructed using a unique method. The features of this method include using a light structure composed of corrugated steel web, a steel upper chord member and super high-strength fiber-reinforced concrete lower chord member in the main girder, on which upper and lower slabs were placed after extrusion, thus forming the completed main girder. To implement this unique construction method, model experiments and analysis were carried out, and the design and construction were considered in detail.
This bridge was awarded the 2006 Japan Society of Civil Engineering Hokkaido Branch Technology Award, and the 2008 Japan Prestressed Concrete Institute Award (technology development category).
