CA RxR 3.13: Fresno Flats (Bonus)

Episode 3.13 is our first bonus episode, bridging the gap while we write Season 4. This bonus episode is a presentation that our co-host, Tom Fearer, gave at the Fresno Flats museum back in May 2025. The presentation focuses on the highways of the Oakhurst area, and was described as: “Since the establishment of the Stockton-Los Angeles Road in 1853 the Sierra Nevada foothills of what is now Madera County has been a hub of highway development. Much of the existing infrastructure in the area was established by the late 1880s with the plotting of the Fresno-Fresno Flats Road and Yosemite Stage Road. The area was of great interest during the early State Highway era due to the desirable access it could provide for logging interests and automotive based recreational travel to Yosemite National Park. Even Minaret Summit was briefly considered for a proposed extension of Interstate 70 into California before the era of environmental impact assessment began.” We’ll pick up in the fall with Season 4, which will cover Route 8 through Route 14. I’m also looking into better software for recording the podcast: In particular, does anyone have opinions on Zencaster, Riverside, or Squadcast?

In this episode, we commence a 3-part exploration of Route 4. This episode starts with all things Route 4: The 4th state route, DOH and Legislative Route 4, and pre-1964 Route 4, finally setting on today’s Route 4. We talk about the LRNs that make up today’s Route 4: LRN 106, LRN 75, and LRN 24. We focus on the first segment of the route, from I-80 in Hercules to I-5 in Stockton. We talk about Route 4 in cities such as Hercules, Martinez, Concord, Antioch, Brentwood, the wetlands, and the Port of Stockton. We also talk about freeway segments, projects, and names along the route. The subsequent two episodes continue Route 4, with 3.03 focusing on the Stockton Crosstown Freeway.

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.

CA RxR 4.01: I-8, Former Route 109, Route 209, and US 80 in San DiegoCA RxR 4.01: I-8, Former Route 109, Route 209, and US 80 in San Diego

Welcome to Season 4 of CA Highways: Route by Route. Episode 4.01 is the first half of our exploration of Route 8. This episode covers the 8th State Highway, which became LRN 36 and later Route 194. It covers LRN 8, which ran from Ignacio (Novato) to Cordelia via Napa, and became parts of Route 37, Route 121, Route 12, and Route 29. We look at Sign Route 8, which became today’s Route 26. And lastly, we look at I-8 in San Diego, including its historical ancestor US 80. This includes former Route 209 to Point Loma, which was part of LRN 12 and possibly US 80, and former Route 109, which became the portion of Route 8 W of I-5 (and you’ll learn why that is not I-8). Episode 4.02 will pick up the story and explore the rest of I-8/US 80 between San Diego and the Arizona Border, including a discussion of the Imperial Highway.
