Any high mountain passes through Montana/Idaho on I-90
Headed to South Dakota from Portland, OR along I-90, curious if there is any high mountain passes like on I-70 through Colorado?

It is a beautiful route but it sure is hilly !! You could drop down to I 80 to Nebraska then turn north. We haul apples out of Washington to NYC at certain times of the year and I 90 is just to much work....on the driver and the truck.
