Shimamatsugawa Bridge, which is located between the Eniwa IC and the Kitahiroshima IC on the Do-O Expressway, has been in operation for about 47 years since its opening in 1946. It is necessary to replace the floor slab because the concrete floor slab is deteriorated and the reinforcing bar is rusted due to salt etc. caused by spraying the antifreezing agent.

In order to replace the concrete slab part of the bridge is In-bound, but you need to do the road closures of lines (New Chitose Airport direction), In-bound the lane line (Shin Chitose Airport direction) Out-bound transferred to the passage of the line (Sapporo direction) The construction will be carried out by minimizing the impact on traffic by using a three-lane switching operation.
