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?
  • If you've pulled Cabbage Hill on I-84 east of Pendleton, the grades and pulls on I-90 in ID and MT will be a piece of cake. The pass on the ID/MT border is the toughest but your Dodge should handle it with ease.
  • 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.
  • We pulled from Missoula to Spokane last summer with our rig and never felt I didn't have enough truck or other concerns. We got to Missoula from Great Falls so did not I-90. But then the Vail pass and the Ike did not bother me either. I am what most would consider a flat lander,but---.
  • Fourth of July Pass, Lookout Pass, Homestake Pass, Bozeman Pass. Homestake and Lookout will be the biggest, not too much different than climbing I-70 out of Denver except for only 2 lanes each way. Bozeman Pass will basically be all downhill when heading east.
