The Muroran Development and Construction Department and the Obihiro Development and Construction Department cooperated with a research company and a construction company to shorten the construction period due to the introduction of ICT and coordinate a number of congested constructions in order to recover as quickly as possible, including the severe winter season. As a result of proceeding with the restoration work for the whole year, we were able to remove the suspension of traffic on October 28, 2017.
