Instead of building roads into the park they could make a train that goes to Paradise and sunrise. that would be sufficent to meet the publics needs.
As far as others roads go. I say lets keep I-90, but all these silly back water roads should be allowed to rot. Lets turn the cascades into one great nature preserve.
Why should we allow people to live near mt rainier anyways? its all going to be destroyed one day, and why should the goverment keep subsidizing people to live in hazard areas!
