Episode 4.13 continues our exploration of Route 14, picking up from the end of the first segment at I-5, and continuing to the junction with US 395 near Inyokern. As usual, along the way, we explore the history of the route, the conversion to freeway, major projects on the route, and naming along the route. This includes a detailed exploration of the start of the route in the Newhall Pass and Solemint area. It also includes an exploration of the “Aerospace Highway” name, and all the firsts that occurred at Edwards AFB and the test center next to the highway. Ep. 4.13 marks the end of the main episodes of Season 4, although we do have a couple of bonus episodes planned for the season break to tide you over. The first bonus episode, 4.14, covers New Idria Road and Hites Cove Road, which are mining roads in San Benito and Mariposa counties.

  1. Thanks for the detailed history; I’ve traveled this route several times. I think this is the only route within L.A. County that has a posted speed limit of 70, from Palmdale north. Separately, the northern segment of the former Sierra Highway, between Backus Rd. and Silver Queen Rd., was in rough shape last time I drove it a few years ago.
    Finally, I also appreciated the explanation for where there highway ’14U’ is posted. I’ve driven that too; I don’t recall seeing posted ‘unrelinquished’ signs elsewhere.

Episode 1.02: Building a State Highway System: The 1920sEpisode 1.02: Building a State Highway System: The 1920s

August 13, 2022August 13, 2022| DanielDaniel| 0 Comments| 8:57 am

This first season of California Highways: Route by Route establishes the background listeners will need for our subsequent route by route podcasts. We’re starting with a history of the state highway system. In Episode 1.01, we discussed how the highway system started and got through the first three bond acts that created a large number of today’s routes. This second episode explores the 1920s: the start of the gas tax, the Melville Act that allowed the state to take over traversable highways through small cities that cannot afford them, as opposed to just rural highways between cities, the impact of the Breed Bill, and the establishment of the Division of Highways (today’s Caltrans). We’ll go over some of the major highways added during this time period, and most importantly, we’ll discuss the start of the Federal Highway system, better known today as the US Highways. We’ve got a special interview related to that subject: Joel Windmiller, President of the California Chapter of the Lincoln Highway Association.

CA RxR 4.02: I-8 and US 80 Between El Cajon and the Arizona BorderCA RxR 4.02: I-8 and US 80 Between El Cajon and the Arizona Border

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.
