A major detour is hitting Medicine Hat drivers for the next couple of days. Dunmore Road has been closed at Kingsway Avenue for CP rail to work on the crossing at the bottom of Dunmore Hill. Crews said that Dunmore road will be closed in both directions until at least tomorrow night for the project. Traffic is being diverted along College Avenue and Kipling Street for the project to be completed. The city is asking that all drivers obey signs and flag persons for the duration of the project.
