Maw, Jim and Jake,
As has been said, the direct route from Durango to Montrose is what's known as the "Million dollar highway". Or, also known as the 550. Now, everyone's tolerances for certain situations, especially in mountain driving conditions will vary. Just what a person, (husband or wife etc.) will think is "scary" is all different in all of us. We have done that road, at least a dozen times in various motorhome towing operations and, also riding our Honda Goldwing.
It's an outstanding drive. One of the most scenic in all of Colorado. There are many out there but, this one it top ranked in scenery. Yep, no guard rails. But, who uses guard rails for driving anyway? All kidding aside, there's quite a bit of hills and grades but, without doubt, once you've done it, you'll want to come back. You'll use lots of low gear for both climbing and going down the other side.
It's amazing to me that others TELL people not to go on this road if they've never done it. You should make that decision for yourself. It's something one has to see for themselves. Now, once you've done it and, it does not appeal to you, then you can make an educated decision as to not travel it again.
