Starting Monday, May 11th, you'll encounter some single lane closures on HWY 191 between Big Sky and West Yellowstone as part of the "North of West Yellowstone project".
The investigation is ongoing and Sheriff Gootkin can only comment on the information covered in the Affidavit of Probable Cause, which is public information.
The Bozeman may see some snow but the concern will be travel conditions for the canyon south towards Big Sky and West Yellowstone along with higher elevations.
