Teton County Sheriff’s Office in Idaho issued a statement on their Facebook page stating “Ski Hill Road at Stateline Road going up to Grand Targhee will be barricaded for several hours to allow the plows to clear the roadway up to the resort. Please do not attempt to go around the barricades as the roadway is not yet plowed and will take several hours for the roadway to be safe for travel up to the resort.”
