In the Madrona neighborhood of Seattle, part of East Pine Street is really just a pedestrian/bicycle path with a trestle bridge spanning a ravine. This house, 3900 E. Pine, has no direct access to any normal street, just to the pedestrian trestle along E. Pine and to another pedestrian trestle reached by a staircase from 39th Avenue, which T-junctions into the one on E. Pine.
