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.

In this episode, we continue our exploration of I-5, the central spine of California. We’re splitting the discussion over 6 episodes, some of which are two-parters. This first episode (a two-parter) looks at the former US 101 segment, from the Mexico Border to Downtown Los Angeles. Part 2, this part, looks at the projects along this segment of I-5, as well as some of the more significant names. Go back to part 1 for a discussion of all things 5: Maritime Highway M-5, the 5th state highway, Legislative Route 5, Sign Route 5, and then I-5. For I-5, we look at the history of the route, and the pieces that led to first the US 101 Bypass and then I-5 in this area. Subsequent episodes will be looking at (3.06) from Downtown LA to Wheeler Ridge, where Route 99 splits, including the Ridge Route; (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.

November 9, 2024November 9, 2024| DanielDaniel| 0 Comment| 8:07 am

In this episode, we continue our a 3-part exploration of Route 4. This episode focused on the Stockton Crosstown Freeway: A short freeway segment of Route 4 that bisects the city of Stockton, essentially running from I-5 to Route 99. We talk about the LRNs that made up this segment: LRN 75, and LRN 24. We spend much of the episode talking about the impact the construction of the route had on Stockton, including an interview with Dr. Paul Ong of UCLA, lead author of a paper (“Stockton’s Crosstown Freeway, Urban Renewal, and Asian Americans: Systemic Causes and Impacts“) that explored the impact of the construction of the Stockton Crosstown Freeway on the Asian-American community. We also talk about the project to complete this freeway, and the names given to the freeway. Our last episode on Route 4 will focus on the segment of Route 4 from Stockton to near Markleeville, including the segment through Ebbetts Pass.

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

November 28, 2025November 28, 2025| DanielDaniel| 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 9th 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.
