text: If it was abandoned, it was abandoned long ago.  The 1943 and 1958 USGS topo maps of the area (http://ngmdb.usgs.gov/maps/TopoView/viewer/#11/47.6154/-117.6704) both show it as an unimproved dirt road.  The 1901 topo doesn't extend quite that far west, but it doesn't show any railroads approaching Spokane from that direction, either.
