'Rt. 80' - that name is ambiguous - I80, US80, Mt80?
I suspect you have I90 in mind. I90 and I15 intersect at Butte. Homestake Pass is a bit east of Butte, and about 1000 ft higher. There's nothing exceptional about the grades on this stretch of interstate.
I thought that when they designed them, there was a limit to the grade allowed on interstates?
