On NW 19th Avenue approaching Everett Street, a shared-lane marking is located at the right side of a right-turn lane. Some expermintal installations have placed a shared-lane arrow at the left side of a right-turn lane. Riding on the left side of a right-turn lane is reasonable for bicycle through travel if right-turning traffic is light. Riding on the right side is not reasonable, as it invites motorists to turn right from bicyclists' left side, but it is consistent with Portland's persistent practice of encouraging bicyclists to overtake right-turning motorists on their right.
Note the three bicyclists in the photo. One bicyclist is riding lawfully in the left lane. Two bicyclists in the next block are riding side by side in a bike lane. One of these bicyclists is riding in the door zone. Motor traffic is light on this street.
Comment by Kat iverson: The two signs in the picture (the arrow on the boom and the "right lane must turn right" on the telephone pole) have supplemental plaques saying "except bicycles." So, it is legal to go straight from the RTOL here, but I've never liked doing that because drivers in the cross street can see only the pavement turn arrow and should expect me to turn. (I've sometimes wondered about the safety of stop sign supplements that say "right turn permitted without stopping".) Early in the block, where the RTOL begins there is a "right lane must turn right" without an exception added, so any through cyclist driving properly would already have moved to the left lane before he can read the exception posted at the intersection.
