The turning lane arrow does not recognize a bike rider and therefore does not provide a bike rider in the turn lane with a green arrow to turn. This is a 5-minute signal adjustment (you've done it for two other intersections with me) and I would be happy to meet a traffic engineer out there so that he/she can calibrate it to recognize a bike. Thanks.
