According to the Jefferson County Sheriff’s Office Interstate 15 is CLOSED starting at 8:37 pm Friday night.
Both North and South bound lanes are closed around mile marker 175 which is just South of Jefferson City.
The reason for the closure is due to a washed out culvert that passes under the interstate.
Montana Department of Transportation is on the scene and is assessing the situation to see how dangerous this is to travel safety.
For now Jefferson County Sheriff’s Office is asking everyone to stay away and let emergency crews and transportation officials work the situation to hopefully resolve this issue.
