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.

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.

Episode 4.10 concludes our exploration of Route 12 with an exploration of the final section of the route: From Route 99 in Lodi to Route 49 near San Andreas. This is a segment that travels through the foothills of the Sierras, running through Lodi, Lockeford, Clements, Valley Springs, and San Andreas along what was originally LRN 24. We also review LRN 12, which we visited before in our episodes on Route 8, for LRN 12 became I-8 between San Diego and El Centro. In our next episode, our attention turns to Route 13, and includes a discussion of LRN 13, the original Sign Route 13 which was quickly renumbered as Sign Route 17, and today’s Route 13 which runs through Oakland and Berkeley, although the route is unconstructed between the Oakland Airport and I-880.

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.
