Two-way LTO
This two-way bicycle left-turn lane installation on Stark SE between 41st and 42nd connects offset segments of a bicycle boulevard. This is one of the very few locations in Portland where there is any special provision for bicyclists to turn left. Question, however: Oregon traffic law prohibits motorists from driving in bike lanes. Is the motorist in the photo here breaking the law by driving in this unusually-placed bike lane? Is a motorist turning left here required by law to keep to the right of the bike lane, and then turn left after its end, possibly forcing a left-turning bicyclist into oncoming traffic on the cross street? The issues are similar on the two-way center bike lane on Hennepin Avenue in Minneapolis, Minnesota.

More usually, a special left-turn bike lane is placed to the right of a left-turn lane for motor vehicles, or adjacent to a median where motor vehicles can not turn left, see example from Palo Alto, California.
