B-H to Terwilliger
Scholls Ferry North to Beaverton-Hillsdale Hwy. Right on B-H and on up to Capitol Hwy., over the hill past Wilson High School, down about a half-mile, then left on Terwilliger. Terwilliger ends up at Sam Jackson; turn right and the road curves around and becomes 6th.
I have heard others express dislike for Beaverton-Hillsdale hwy, but I find it not bad at all, once you cross the line into Multnomah county, which is where the bike lane starts. There is a tricky spot right where B-H turns into Capitol Hwy: there is a turn-off for Bertha blvd. where cars are supposed to (according to the signage) "Yield to Bikes", but they *never* do.
This route has the least elevation gain, and Terwilliger is a beautiful stretch of road.
