We have a Highway 395 out here on the California/Nevada border that is interesting too. High Sierra on one side, sage brush desert on the other, with lots of Gold Rush history along the way.
Another one is I-5 from Lake Shasta, CA to the Canadian border. It is heavily forested most of the way, with lots of snowy peaks and lakes to look at.
