Unable to answer "Are pedestrians forbidden to walk on this road without sidewalk here?" – North Santiam Highway [OR 22;OR 99E Bus] (Trunk Road) – https://osm.org/way/34894567 via StreetComplete 58.1:

Street complete wants to know if it's forbidden for people to walk along the street here. There's room for it and I'm sure people do and it looks like there's a bike lane, but I don't know if it's actually legal. The presence of sidewalks and crosswalks on either side of the bridge suggest that it's at least tolerated
