The Historic Highway 99 Association of California, in conjunction with the Ridge Route Preservation Organization, has produced a video on the basics of the Ridge Route and some of the features that make the road unique. Learn about the curbs, rails, footprints of all types, tire tracks, and more that can be found on the road. They also talk about the different pavement types on the road as well as how you can get up there and see the road yourself.

The Historic Highway 99 Association of California has also produced other videos talking about other sections of the highway, including the bridges over the Santa Clara River and Castaic Creek in their “History along US 99” series.
