Polonio Pass is the second of two passes US 466 over through the Coast Ranges. In the late 1950’s, a major realignment was undertaken to straighten the roadway and add passing lanes. A significant portion of the original alignment remains intact today and driveable for most vehicles. Wooden railing and some striping still remain on the crumbling pavement.
