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.

CA RxR 3.08: I-5: Whatever Happened to I-5WCA RxR 3.08: I-5: Whatever Happened to I-5W

March 13, 2025March 13, 2025| DanielDaniel| 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.

Next up in our exploration of I-5: the segment between the I-5 / Route 99 split and where I-5 meets former US 99W (now Route 113) in Woodland. Generally known as the “Westside Highway”, this was mostly a completely new routing for I-5 along LRN 238, although some portions paralleled former US 50 between Stockton and Sacramento, and Sign Route 16 between Sacramento and near Route 113 in Woodland/Yolo.  As usual, we cover the history of the route, naming, and projects. Subsequent episodes will be looking at (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.

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.
