NEP, give this route a look - pretty direct, & for the most lower traffic:

starts at E burnside/i-205 path & utilizes the Springwater out to Boring. Back roads from there to Hwy 224, then using Eagle Creek Rd. which paralllels 224 in to Estacada. You can stay on 224 if you prefer, i think the shoulder's decent.
