bsmith0404, Howdy;
Have you "explored" the route with Google Earth? You can see what the
roads actually look like (be sure to check the date of the photos on the
bottom row), and watch the elevations as the roads go up & down the
Rockies. Here's a link to Co.DOT for information.

You do realize that you are planning to drive up the spine of the Rockies?
Alt. route would be US-160 to I-25 to I-70 ...
By the way ...how are you planning to get
to Durango???
