Four. Construction overview

 道央自動車道 苫小牧西IC~苫小牧東IC間に位置する勇払川橋は、昭和55年の開通から約38年が経過し、車両の大型化による輪荷重の増加で発生した微細なひび割れや、冬期間の凍結防止剤散布による塩分などが原因となり、コンクリート床版の劣化や鉄筋に錆が生じているため、床版の取り替え工事を実施する必要があります。

In order to replace the concrete floor slab of the bridge, it is necessary to close the Out-bound line (for Sapporo), but one of the two lanes for the In-bound line (for Muroran) should be closed for the Out-bound line (for Sapporo). By carrying out transfer and face-to-face traffic, construction will be carried out with minimal impact on traffic.

Main work contents

By replacing the deteriorated existing concrete slab with a new slab, it will be reborn as an Expressway that can be used safely and comfortably.
