https://www.google.com/maps/@47.6757218,-117.3849352,3a,75y,70.4h,83.24t/data=!3m6!1e1!3m4!1sqdzvokjXjkutvCYJLOWh_A!2e0!7i13312!8i6656!5m1!1e4

That's a bicycle lane on the road, plus a distinct bicycle path running
parallel to it.  It's mapped in OSM as a "cycleway=lane" on the road and a "highway=cycleway" running parallel to it.
