There was no information available about whether there were injuries or traffic being re-routed.

Elsewhere, the Bassano RCMP issued an advisory warning motorists to avoid travel on Highway 1 between Bassano and Brooks, where they said icy road conditions have contributed to to at least four vehicles going into the ditch along that stretch of road.

Another semi jacknifed off the road at Highway 845 and 25.

Medicine Hat Police urged motorists to avoid the area around the Trans Canada Highway at Box Springs Road, where there was a motor vehicle collision, with poor road conditions.
