Interstate 90 was a parking lot. Traffic came to a complete stand-still many times due to crashes, pile ups, and slide offs. US 93 had dozens of it's own accidents. Montana is having a very rough week on the roads.
By 11am there were over 80 incidents on Montana highways. Crashes, slide-offs and jackknifed semis were wreaking havoc on traffic flow and causing backups and delays. Snow, wind and cold temperatures are creating dangerous conditions and more is on the way.
By late Monday morning, there were at least 2 dozen incidents on Montana highways that required Highway Patrol to be dispatched. Snow covered roads and low visibility guarantees there will be at least more slide-offs before days end.
