As for rumble strips on US 2 between West Glacier and Cut Bank, it depends on location. Between West Glacier (US 2 milepost 153) and milepost 169, there is little or no paved shoulder (zero to 1 foot) and no rumble strips. Between milepost 169 and 181 near Essex, there are 3-4 foot paved shoulders with newly installed rumble strips (summer 2026) that leaves 1 to 2 feet of usable paved shoulder. From Essex to the top of Marais Pass (milepost 198), paved shoulders vary from 1 to 3 feet with no rumble strips. From Marais Pass to East Glacier (milepost 208) there is little or no paved shoulder (zero to 2 feet) with no rumble strips. From East Glacier to Cut Bank (milepost 255), there are wide paved shoulders most of the time (5 to 8 feet) where there is plenty of space between the rumble strips and the edge of the pavement. The exceptions are in passing lane areas between East Glacier and Browning where the paved shoulder disappears at times and yes, rumble strips continue and going through parts of Browning (milepost 221 to 223). Yes, there are some highways on the Northern Tier in most of the states that the Northern Tier goes through where rumble strips are either on the edge line with no paved shoulder or cover all of a narrow paved shoulder. I recommend looking at Google Street View to preview the route.
