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.

We’ll go over the freeway plans, discuss relinquishments, names, and some current plans.

Episode 4.09 continues our exploration of Route 12 through an exploration of the middle section of the route: From Fairfield/Cordelia through the “Drive to Stay Alive” corridor, on through the wetlands of Rio Vista, and into the central valley and Lodi. We explore the big change in routing that happened in Rio Vista. We also look at some major projects within this segment, as well as some of the interesting names. We also review LRN 12, which we visited before in our episodes on Route 8, for LRN 12 became I-8 between San Diego and El Centro. Our exploration of Route 12 will conclude in Episode 4.10, which will cover Route 12 from Route 99 to the Sierra Foothill and San Andreas, where it meets Route 49.

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.
