2. Main construction contents

  • Ramp bridge construction work: At Otaru JCT, which connects the Sapporo-Otaru Expressway and SHIRIBESHI EXPRESSWAY, construction is underway on the C ramp, which runs from Otaru via the Sapporo-Otaru Expressway towards Yoichi on SHIRIBESHI EXPRESSWAY. During this road closure, construction will be carried out on the ramp bridge that will intersect with the Sapporo-Otaru Expressway.
    A multi-axle trolley will be used for the erection work, which will block the driving and passing lanes of the Sapporo-Otsuka Expressway, so road closures will be in place.

  • Maintenance and repair work: Maintenance and repair work (road surface repairs, tunnel inspections, etc.) will be carried out between SHIRIBESHI EXPRESSWAY Yoichi IC and Otaru JCT. This section has only one lane in each direction, so lane restrictions are not possible, and so the road will be closed to traffic.

To minimize inconvenience to our customers, we will be closing the road on weekday nights when traffic volume is low. We appreciate your understanding and cooperation.
