Episode 4.12 starts our exploration of the last route of this season: Route 14. Segment (a) of Route 14 is the unbuilt “Reseda to the Sea” freeway, so we take this opportunity to discuss the unbuilt freeways of the San Fernando Valley: the Reseda Freeway (Route 14), the Whitnall Freeway (Route 64), the Laurel Canyon Freeway (Route 170), and the freeway plans for Sunland Tujunga, the Angeles National Forest (Route 118, Route 122, Route 249), and the plan for the Mulholland Expressway (Route 268). We also discuss LRN 14 (part of US 40) and Sign Route 14 (which became Route 91). We’ll discuss the built portion of Route 14 between I-5 and US 395 in the last official season 4 episode. With respect to Tom’s sound quality: It’s better. Daniel’s mic has an occasional “pop” or “thump” problems; we’ll hopefully fix that in Ep 4.13. We’re also working to line up 2-3 bonus episodes during the season break.

CA RxR 4.05: I-10: Santa Monica FreewayCA RxR 4.05: I-10: Santa Monica Freeway

January 7, 2026January 7, 2026| DanielDaniel| 0 Comment| 6:04 am

With Episode 4.05, we turn our attention to Route 10. This first episode on Route 10 starts with an exploration of the 10th route (the last ordinal route we’ll do), which was the Emigrant Gap Highway, and became the basis for LRN 37. This became part of the Lincoln Highway, then US 40, and is now part of I-80 from Sacramento to Nevada. We look at LRN 10, which became Route 198 from US 101 near San Lucas to Sequoia National Park. We then explore Sign Route 10 (which we discussed in our episode on I-5 in Los Angeles county), which ran from US 101A to US 101, later becoming Route 42 and US 101 Bypass, and eventually I-105 and I-5. Lastly, we turn to post-1964 Route 10, which is today’s I-10. In this episode, we focus on the first segment:  “From Route 1 in Santa Monica to Route 5 near Seventh Street in Los Angeles”, which is today’s Santa Monica Freeway. We look at its origins as Sign Route 6, which became Sign Route 26 along LRN 173, LRN 166, and LRN 171. We focus on LRN 173 (LRN 166 and LRN 171 were discussed in our episode on I-5 in Los Angeles county, as well as our episode on Route 6), which was Olympic Blvd. We explore the history of the Santa Monica Freeway segment, the experiments tried along this highway, some significant projects along this segment, and some significant names on this segment.

We will complete our exploration of Route 10 in Episode 4.06, which explores the San Bernardino Freeway: Its origins in LRN 26 and LRN 64 and the Ramona Airline. The history and strange intertwinings of the US highways that were signed on Route 10: US 60, US 70, and US 99. The transition to I-10 and the story of Route 10S. Lastly, we’ll cover projects and names on the segment.

September 29, 2024September 29, 2024| DanielDaniel| 0 Comment| 10:29 am

Welcome to Season 3 of California Highways: Route by Route. We promised that the season would start in September, and we’re making it by the wire. Season 3 covers Routes 3 through 7; this is the first episode covering Route 3, which is in Northwest California near Weaverville and Route 299. In this episode, we talk about all things “three”: The third state route, Legislative Route 3, Sign Route 3, and finally the current Route 3. For the current Route 3, we talk about the history of the route, projects currently ongoing on the route, and some naming along the route. We even have a digression on the proposed Interstate 3. We also talk about the state scenic highway system, and how routes earn the golden poppy. The next three episodes will be focused on Route 4.

November 7, 2025November 7, 2025| DanielDaniel| 0 Comment| 11:35 am

This is Episode 4.02, which continues our exploration of Route 8, better known as Interstate 8. In this episode, we focus on the portion of I-8 from La Mesa (just outside of San Diego) to the Arizona border. We look at not only current I-8, but the routing of the predecessor route, US 80. We discuss the communities of La Mesa and El Cajon, Alpine and Descanso, Boulevard, the Mountain Springs Grade, Jacumba, Ocatillo (with a digression on the Imperial Highway), El Centro, Holtville and the Algondenes Dunes (with a digression on the Plank Road), Winterhaven and Yuma. We also briefly talk about the interesting routing of US 80 within Arizona, and how it differs from I-8. We talk about historical routings, projects along the route, and some significant names. In the next episode, we’ll turn our attention to Route 9, which currently runs from Santa Cruz to Los Gatos, but which once ran all the way to Castro Valley.
