Effective Immediately due to a slide on the roadway US-89/US-87/MT-3 at Mile Marker 72.1 (east of Great Falls between Belt and the Junction of US-87 and US-89) is closed to ALL permitted loads. There is a detour in place but this detour will be difficult for truck traffic to maneuver and will not be able to accommodate any loads that are operating under a special permit (oversize, overlength, overheight and overweight). You will need to find an alternative route.
If you have any questions or concerns, please contact Dan Kiely at (406) 444-7629 or dkiely@mt.gov.
