ATTENTION:
US 212 Route Restrictions and Closures – In Effect - June 20, 2026 – June 25, 2026, for the Little Bighorn 150-year celebration.
Please be advised that significant travel impacts are expected along US 212 (from the Wyoming border near Alzada, MT to Crow Agency, MT) due to a large, organized horse ride event. Carriers should anticipate closures and travel restrictions during the event and plan alternate routes accordingly.
VMS messaging will be in place in South Dakota, Billings, Crow Agency, Miles City, and several local areas. The VMS signs will advise all CMV’s to use an alternate route and no oversize or overweight loads allowed on US 212. This is in effect for term permits as well.
The event is scheduled for June 20, 2026, through June 25, 2026.
Due to the size of the event and associated traffic impacts, oversize and overweight movements on US 212 will not be permitted to ensure the safety of the traveling public.
Additional information regarding specific closures, restrictions, and impacts will be provided as it becomes available.
Please monitor permit notifications and plan accordingly to avoid delays.
If there are any questions or if routing assistance is needed, please contact the MCS Permitting Office at 406-444-7262.
