Found this ride on RideWithGPS. Route starts at the Hondo dog park in Hillsboro, off NE Century Blvd and across the road from Hillsboro Hops Stadium. The route creator did a great job with this ride, especially getting out of Hillsboro. Easy and safe just before Witch Hazel Rd. Have to cross Cornell Rd and TV Highway, but there are traffic signals on both. The next section heads southwest on Rood Bridge Rd then west on Burkhalter Rd. The climbing begins at Riedweg Rd. There are a couple short, fairly steep climbs to Dober Rd, then a couple more short climbs to Iowa Hill Rd. Enjoy a nice descent on Iowa Hill Rd, then some flats to Blooming. There are a couple more short climbs on Blooming Fern Rd to Fern Hill Rd. Cross Highway 47 at Gaston, mile 24.9. There is a park, Brown Park, that makes a nice rest stop. Even has a blue room. Ride Old Highway 47 for a few miles to the actual Highway 47 (mile 29,3). Fortunately, it is only a 0.4 mile stretch on Highway 47 until a left turn at SW Dudney Rd. Need to exercise caution here getting into the turn lane. Continue on SW Dilley Rd then go left at Stringtown Rd. Ride Stringtown Rd to SW Ritchey Rd, which eventually brings you into Forest Grove. Ride E Street (actually Highway 8) to Thatcher Rd. Veer right onto Thatcher. There is a big park, Thatcher City Park, that makes a nice rest stop. The final 13 miles goes through Verboort and continues east to Evergreen Rd and finally back to 59th to the dog park.
