Best route from Los Angeles to Durango CO - Class A

I would really hope you do that drive in two days....at least! There is so much beauty in that whole area - once you get off I-40.

There are many routes you can take and none have bridges to worry about. It just depends what you want to see along the way. From I-40 Flagstaff, AZ you could take Hwy 89 north to 160 and take in Monument Valley. 191 and 491 are also good roads.
