Driving to vegas

[sst7250]

IMO I40 in NM and AZ is almost criminal in places. I have driven the route MANY times this past year and its bad. Coming from KC cutting through Kansas is nice smooth roads.
Until you get to Tucumcari and hit 40. I like taking 70 personally especially if I can plane the stretch through Denver at night. There are climbs both ways. One big one on 70 and three smaller ones across 40. Fuel prices once you get to NM are pretty high or at least were on our trip back from Indy. AS mentioned you will be hitting alot of construction through Vegas if oyu choose the 40 route.

I've done it both ways. 40 is usually the plan, just because of weather issues in the mountains. Last time there were predicted snow storms along 40, which did happen. 70 was smooth sailing.

The plan was to stop in Denver for the night, but the truck stop was full so ended up driving the Rockies all through the night. I've still never actually seen them but the driving wasn't an issue.
