Chicago>Denver>Glenwod Springs>Bryce Canyn>Tucson. November

Going west from Denver to Glenwood Springs on I-70 has two major passes.

Eisenhoswer Tunnel is 11,013' with 6 miles of 7% and 2-3 miles of 5-6%. And then down. After a bit you get to Vail Pass. which is 10,603'. Another 7% for 7-8 miles.

And some curves as well with speed reduced signs.

Then you get to Glenwood Canyon which is beautiful - very beautiful - but curvy as well.

It is all interstate so well protected on the sides, etc.
