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.

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.

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.
