CA RxR 4.03: Route 9: Santa Cruz and SaratogaCA RxR 4.03: Route 9: Santa Cruz and Saratoga

November 28, 2025| Daniel| 0 Comment| 5:50 am

Episode 4.03 starts a pair of episodes that explore Route 9, which in its post-1964 version runs from Santa Cruz to Saratoga and Los Gatos. Before 1964, Route 9 continued N up to the Mountain View area, and then across to Milpitas, and up to the Castro Valley. This episode (4.03) covers the current Route 9 from Santa Cruz to Los Gatos; the next episode (4.04) covers the remainder of pre-1964 Sign Route 9 through Mountain View, Milpitas, and up through Hayward and the Castro Valley. This episode also explores the 9^th State Route between Peanut and Kuntz (now Mad River), and LRN 9. LRN 9 ran all the way from Ventura to San Bernardino, and was Sign Route 118 from Ventura to Pasadena, and US 66 from Pasadena to San Bernardino. As always, we’ll talk about historical routings, projects along the route, and some significant names. As noted, the next episode explores the remainder of pre-1964 Sign Route 9 from Saratoga through Milpitas to the Castro Valley.

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, 2025| Daniel| 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.

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

October 17, 2025| Daniel| 0 Comment| 6:46 am

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.

CA RxR 3.13: Fresno Flats (Bonus)CA RxR 3.13: Fresno Flats (Bonus)

July 18, 2025| Daniel| 0 Comment| 8:09 pm

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?

CA RxR 3.12: Route 7: From Long Beach to the BorderCA RxR 3.12: Route 7: From Long Beach to the Border

June 22, 2025| Daniel| 0 Comment| 1:18 pm

Episode 3.12 brings Season 3 to a close, modulo our bonus episodes. In Episode 3.12, we explore all things Route 7. As is our tradition, we start by looking into the 7^th state highway, the Kings River Canyon Road, and LRN 7, which included portions of US 40 and US 99W. We then turn our attention to various incarnations of Route 7: Sign Route 7, both the section along the Eastern Sierras that is now US 395 and US 6 and the section that became Sepulveda Blvd in Los Angeles; 1964-1981 Route 7, which was the Long Beach Freeway before it was renumbered into I-710; and the current Route 7, which is a small border connection route near a new entry point near Calexico. We’ll then be taking a short break, during which there will be some bonus episodes. We’ll pick up in the fall with Season 4, which will cover Route 8 through Route 14. I’m also going to be working on improving the sound quality of the podcast once I retire in July.

CA RxR 3.11: US 6: A Major Route no MoreCA RxR 3.11: US 6: A Major Route no More

May 23, 2025| Daniel| 0 Comment| 11:44 am

With Episode 3.11, we turn our attention to Route 6, better known as US 6. As is our tradition, we start by looking into the 6^th state highway, and the LRN 6, and then the route that was originally signed as Sign Route 6. We then turn our attention to US 6, looking at the history of the route, and the historical routings in Long Beach, Los Angeles, Newhall, the Antelope Valley, the Eastern Sierras, and Bishop. We also talk about El Camino Sierra, the Midland Trail, and the proposals for trans-Sierra highways that would have included US 6. Lastly, we look at US 6 today: the portion between Bishop and the Nevada State line. Next up: The last episode of Season 3, where we talk about Route 7: both the current short route near the border, and the more interesting historical routings of LRN 7, Sign Route 7, and the original 1964 Route 7.

CA RxR 3.09: I-5: Former US 99WCA RxR 3.09: I-5: Former US 99W

April 6, 2025| Daniel| 0 Comment| 12:25 pm

Episode 3.09 continues our exploration of I-5 with the segment from Sacramento to Red Bluff, which primarily incorporates the former LRN 7 / US 99W routing between Woodland and Red Bluff, and a new routing that roughly followed LRN 238, then LRN 50 and LRN 232 between Sacramento and Woodland (near former Sign Route 16 and Sign Route 24). We talk about this history of this segment, as well as some discussion of historical routings in Natomas, Woodland, Williams, Willows, Corning, and Red Bluff. Our exploration of I-5 finishes in Episode 3.10, where we explore the former LRN 3/US 99 segment between Red Bluff and the Oregon Border.

March 13, 2025| Daniel| 0 Comment| 2:49 pm

Episode 3.08 continues our exploration of I-5 with a slight digression: A discussion about I-5W. In the late 1950s, I-5W was proposed as a spur route from I-5 running along what is today Route 132, I-580 (both the Tracy Diagonal and the former US 50 portion between the I-205/I-580 junction and Oakland/Berkeley), I-80 between Berkeley and near Vacaville, and I-505 between Vacaville and I-5. This short episode explores these pieces and their history. In Episode 3.09, we return to I-5 proper when we explore the former US 99W section of I-5 between Woodland and Red Bluff.

January 12, 2025| Daniel| 0 Comment| 11:00 am

Our I-5 exploration continues, with a focus on the segment of I-5 from the US 101 split in Downtown Los Angeles to the Route 99 split in Wheeler Ridge. This episode, Part 1 of 3.06, after a recap on LRN 5 and Sign Route 5, focuses on the history of I-5 from Downtown LA (DTLA) to and through the Newhall Pass. We explore the history of LRN 4 and LRN 161, the timeline of freeway construction to and through Burbank, the history of Route 5S (Colorado Blvd), and a dive into the history of routings through the Newhall Pass and in Saugus. We also talk about the Interstate number submissions for I-5, and have some updates on the projects we discussed in Episode 3.05p2. Our special guest this episode is Sydney Croasmun of the Ridge Route Preservation Organization. Sydney brings her expertise to our discussion in Part 2, when we’re going in detail over the Ridge Route. Part 2 also discusses projects and naming in this section, especially the history of the “Grapevine” name. Subsequent episodes will be looking at (3.07) the Westerly Routing; (3.08) the planned I-5W; (3.09) the former US 99W portion from Sacramento to Redding; and (3.09) the portion from Redding to the Oregon Border.

CA RxR 3.04: Route 4: The SierrasCA RxR 3.04: Route 4: The Sierras

November 29, 2024| Daniel| 0 Comment| 7:14 am

In this episode, we complete our exploration of Route 4, covering the segments from Stockton and Route 99 through Angels Camp, and then on over the Sierras to Route 89 near Markleville. This includes segments that go through Gold Country, as well as the Ebbetts Pass segment that includes some very steep grades. Along the way, we look at the history of the route in these areas, projects along the way, and naming of the route. As always, we conclude with a discussion of this segment of the route after the credits. Next up: The first of six episodes (some with two parts, making it really eight episodes) covering Interstate 5. Episode 3.05 looks at the former US 101 portion from the Mexico border to downtown Los Angeles.
