How about actually making it a railroad again, instead of a highway!!
I know this has been brought up before, but now that maybe the states are involved it might be considered at least. The problem is that most of it lies in Colorado. However, what about a joint railroad between the two existing ones, operated jointly with shared revenues, and expenses.
I know its a lot to consider, but before this road is built it should be given one last look. Once the road is in, there is no turning back!
