I'm curious about what % grades we're talking about in these different routes. It's all relative; none of it is "flat." As an Easterner I'd really like to know how steep those Rocky Mt. highways are. Does anyone know?

My experience has been that the grades out west are not any steeper than the grades in the east...they are just longer.
As a general rule, on interstates, the max grades are the same. On the secondary roads, some of the mountain grades in the east are actually steeper. Of course there are exceptions...
