The next rest area heading north is 97 miles...heading south i am not sure. There are rest areas every 70 to 100 miles along the interstate but not all are Dept of Transportation run rest stops.
Go to Google maps and type in rest stops in Montana. They are all open 24/7
Sorry, I don't remember.
Not too far going West, just before Missoula or just stop in Missoula. I forget going East.
About half way or a bit more towards Missoula I believe. If you are going the other way it's in Bozeman.
