This is going to be a fast trip, unfortunately... the goal is to leave on a Sunday morning in and arrive sometime Monday night in Los Angeles. The trip is also in early January, so a route with less volatile weather and safer roads would be preferable.
Which routing would be best?
I-25 south to Albuquerque, then I-40 west to Winslow or Flagstaff, AZ for the night, stopping by the Grand Canyon the next day, and then finishing the drive to Los Angeles via I-40 and I-15 in the afternoon/evening
2) I-70 west into Utah, then US 191 and US 163 south through Utah followed by US 160 west through northeastern Arizona, spending the night in Kayenta or Tuba City. Visiting the Grand Canyon and then continuing on to LA the next day.
I guess I am concerned about I-70 through the Rockies in January, as well as the quality of the US Highways through Utah and Arizona... it does seem like that routing would be shorter, but wouldn't the all-interstate route be a lot faster? I also wonder if there might be less accomodation options available in the Navajo Nation as compared to along the I-40 corridor...
Any help would be appreciated :)
Also: The car I'll be driving is a 1996 Honda Civic, if that makes a difference.
