You can. Don't go across 60 as you have to go down the Salt River Canyon and there is a U 90 degree across the river and a 90 degree followed by hairpins back up.I drove a truck in Co, Az and NM and it and the North Pass on 114 in Co are 2 bad roads. Just go to Flagstaff and take the Interstate (I17) down then go east on the Superstition Freeway to Apache Jct. It's safer if you aren't a mountain driver and just as fast. That's my Opinion as a Professional Truck Driver and I drove 60 every week for 3 years out and back.
