The lights at N 175th St and Midvale Ave N in Shoreline. The Interurban Trail goes through the intersection (North-South) and they have buttons for the trail users / pedestrians. However, if you are in the main (traffic) lane on Midvale, the light will never change. I don't see any bike detector, either.
