Episode 1.01 – Before 1920 – Building a State Highway System

Welcome to the first season of California Highways: Route by Route. This first season will be establishing the background listeners will need for our subsequent route by route podcasts. We’ll start with a history of the state highway system. We’ll then explore how highways are numbered in the state. Lastly, we’ll look at how highways are named, and some of the organizations involved with state highways.

This first episode explores the start of the state highway system. We’ll start with the humble beginnings with the first routes defined by the legislature, and then go into the routes defined by the first three bond acts. We’ll also explore the Good Roads movement, and we’ll have a special interview with Adam Prince of Gribblenation.

We explore the big change in routing that happened in Rio Vista. We also look at some major projects within this segment, as well as some of the interesting names.

CA RxR 4.14: Bonus: New Idria Road and Hites Cove RoadCA RxR 4.14: Bonus: New Idria Road and Hites Cove Road

Episode 4.14 is the first of two bonus episodes. It tells the story of the corridors of New Idria Road and Hites Cove Road. Both of these historic highway corridors lead to mining in Central California. This episode is based off blogs released on Gribblenation during October 2025 and May 2026. New Idria Road is an approximately 21.5-mile rural highway located in the Diablo Range of San Benito County. It branches off of Panoche Road, and winds its way south-ish through the Diablo range to the ghost mining town of Idria, continuing as Clear Creek Road. Hites Cove Road is an approximately seven-mile rural highway corridor located in the Sierra Nevada range of Mariposa County, south of Route 140, and west of El Portal. Hites Cove, and its successor forest and OHV trail roads, leads to the ghost town of Hites Cove on the south fork of the Merced River. Two interesting stories about two interesting ghost towns. Next up: Our second bonus episode to close out Season 4: A roundtable discussion with Adam Prince and Doug Kerr as we celebrate the 25th anniversary of the start of Gribblenation.
