This bridge is a long, elevated bridge (length 739.0m, height 30m) that crosses the Moheji River and the prefectural highway of Kamiisho-assabu line. This bridge features construction that used a span-by-span method with precast segments, the first time such a method has been applied in Hokkaido. The integrated rigid frame structure exceeds 500m in length, and the pier cross sections may be affected by creep, dry contraction, prestress and temperature changes. To reduce this influence, various new methods were adopted in the design and construction.
Although this bridge is located in the southern part of Hokkaido, the temperatures during construction still dropped below zero. To realize high quality and accurate segment production, a short-line match casting method was utilized, along with compact, high-efficiency curing equipment.
