Montana Department Of Transportation App
Zimmerman Trail is closed until November. The west Laurel Interchange is down to one lane in places.
And if you're traveling, you should download the Montana Department Of Transportation App. It shows all road construction, state wide; It also shows road incidents. So, you can possibly save yourself some time by avoiding accidents that other motorist won't know about.
It also gives you winter road conditions plus access to cameras across the state.
And it's so easy to operate, even I can do it!
