Hey 160 from Cortez CO to Hwy 89 Flagstaff?

Did the bulk of that route enroute to the Grand Canyon 2 years ago. Fuel at the locations noted above. The road is fine with a caveat; in many places (like most of the route) there's barely any sort of shoulder on the roadway, should you need to pull off for whatever reason. And Verizon cell service was practically non-existent with the exception of near any of the areas of any population along the route.

The roads are fine except as you mentioned, they could be a bit lonely although they are reasonably well traveled. Fuel is available but, the Navajo Nation has suffered the state's worst Covid-19 outbreak. You could run into curtailed hours or temporarily closed businesses. Pretty much everything along I-40 is operating normally so that may be the best route to avoid anxiety.

Just to add, you'll also be traveling during wildfire season (already upon us) so always check routes and designations for closures or restrictions.

Don't want small roads take 491 to I40 little longer but under an hour different.

Mostly very limited to none.

It is getting better. The Navajo Nation is working to provide 4G coverage for the entire nation, but I don't know how far the plan has progressed.

Road is fine. Fuel in Cortez, Towac, Kayenta, Tuba City, and Cameron

It has been a number of years, but we have used route 160 from Cortez to route 98 to get to Page. All good 2 lane road. I recall that we stopped at the McDonalds at the junction with route 163 in Kayenta. Google Maps shows a Chevron Station with diesel there and several other places for food. Google Maps also shows a Shell Station with diesel at Shonto Marketplace at the junction of routes 98 and 160. Can't comment on cell service.

Enjoy Your trip!
