You can do it that way. It is essentially what I described in earlier post.
I have ridden from the Junction of 97 and 58 to 138 and then over the top as part of a tour I was doing finishing up. I was wild camping with the mosquitos right near the junction. I lived in a small town just north of Roseburg, and it was my last day, 139 miles. I have not ridden on 58, but I drive it a lot. I'm a ski patroller and the area I patrol is at the top of Willamette Pass. I've driven it a lot, actually too much, and with a biker's eye. IMO- it would not be a bad ride. There is a lot of truck traffic because 58 heads diagonally southeast and is a good way to connect to 97 southbound. Highway 97, while busy, has good wide shoulders. That is the way we drive to Crater Lake. I live a little northeast of Eugene.
