The issue is crossing the Willamette. I think I would probably opt for crossing the Wheatland Ferry (head east from Hopewell), go through Brooks and the Labish Flats (65th & 62nd) to Hazelgreen, then Howell Prairie Road.
In this manner you would avoid Salem altogether, since your stated end is to drop down towards Detroit anyway...
The portion through Lafayette is very nice indeed at this time of year. I did that portion last weekend as part of a 60 mile training ride. There are several stretches of wildlife wetland refuge along that portion and there was an incredible variety of birds out, especially along the Fernhill section.
