UPDATE: By 3pm the full stretch was re-opened, but there are still spots of snow and ice on the roads.
Severe cross winds and blowing snow have caused Montana Department of Transportation to close I-15 in both directions from Dillon to Monida. The interstate is also closed on the Idaho side from Monida to Dubois.
Idaho Transportation Department and MDT both say conditions for driving are too dangerous and the road will remain closed until those conditions get better.
This is a developing story and we will continue to update this post as new information becomes available.
