   CA RxR 5.01: I-15 (Part 1): South of Temecula

   Welcome to Season 5. We start the season with three episodes covering Route 15. The first (this episode), covers LRN 15, Sign Route 15, and today's Route 15 between San Diego and Temecula. LRN 15 ran from what is now Route 1 near Fort Bragg to what is today's I-80 near Emigrant Gap; it is today's Route 20. Sign Route 15 is what became Route 7 and later I-710, and is today's Long Beach Freeway. We have some interesting exploration of the ends of Sign Route 15 in Pasadena and Long Beach. We then turn to the main focus of the episode: Route 15, which runs from San Diego to the Nevada border, and has a complicated history. So complicated, in fact, that this episode focuses only on the portion between San Diego and Temecula, exploring both former Route 103 and US 395, as well as the transition from US 395 to today's I-15 routing. Episode 5.02 will cover Temecula to Devore, and explore the history of I-15, I-15E, I-215, Route 71, US 91, US 395, and Route 194. Lastly, Episode 5.03 will cover Devore to Nevada, including I-15, US 395, US 66, US 91, and US 466 (with a bit of Route 195 and US 95 thrown in).For more information, and for additional links, see this episode's page at the show's forever home on CARouteByRoute.org (https://caroutebyroute.org/2026/09/18/ca-rxr-5-01-i-15-part-1-south-of-temecula/).

   CA 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.For more information, and additional links, see this episode's page on its forever home, CARoutebyRoute.org (https://caroutebyroute.org/2026/07/28/ca-rxr-4-14-bonus-new-idria-road-and-hites-cove-road).
