Proposed Auto Club State Route Signage

Proposed Auto Club State Route Signage

In this episode, we’re continuing to explore the history of the State Highway System, focusing on the 1930s and the early 1940s. This is part of our first season of California Highways: Route by Route, where we are exploring the background needed for our route by route journal. In this episode, we’ll see the establishment of the legislative route system, the creation of state sign routes and the signage by the auto club, a major expansion of the state highway system, and continuing growth on the Federal side, laying the groundwork for the eventual interstates. This episode also features an interview with Morgan Yates, Archivist of the Auto Club of Southern California. During his interview, Morgan shared a picture of alternative state routing signs proposed by the ACSC (included here thanks to the auto club). You can write to Morgan at: Corporate Archivist; Automobile Club of Southern California; 2601 S. Figueroa St., MS H-118; Los Angeles, CA 90007.
