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.

CA RxR 4.07: Route 11: From Pasadena to the BorderCA RxR 4.07: Route 11: From Pasadena to the Border

February 21, 2026February 21, 2026| DanielDaniel| 0 Comment| 8:01 am

In Episode 4.07, we examine Route 11.  We’ll start by exploring LRN 11, which was essentially the first state highway, running from Sacramento to Placerville, later extended to run from Antioch to the Nevada State Line near Lake Tahoe. Today, it is primarily US 50 with a bit of Route 160. We then the original Sign Route 11, which was LRN 165 and LRN 205, and is today’s Route 110. It was also US 60, and is perhaps better known as the Harbor Freeway and the Pasadena Freeway / Arroyo Seco Parkway. We explore the history and various routings of Sign Route 11, including the history of the Figueroa Tunnels. Lastly, we explore the current Route 11, which is a short route near the Mexico border that connects the San Diego Freeway System (Route 905/Route 125) to the Otay Mesa East port of entry.

On deck: In episode 4.08, we start a three-episode group that will cover Route 12. Route 12 runs from Route 1 near Valley Ford to US 101 and thence to Sonoma area. It then runs through Napa to meet I-80 near Cordelia. That part is episode 4.08. Episode 4.09 will cover Route 12 from I-80 near Suisan City through the Sacramento Wetlands to Lodi and Route 99. Lastly, Episode 4.10 will cover Route 12 from Route 99 to the Sierra Foothill and San Andreas, where it meets Route 49.

CARxR Ep. 1.05: Chronology – The Great Renumbering and New FreewaysCARxR Ep. 1.05: Chronology – The Great Renumbering and New Freeways

November 15, 2022November 15, 2022| DanielDaniel| 0 Comment| 9:35 pm

In this episode, we’re continuing to explore the history of the State Highway System, focusing on the construction boom in the 1960s under the administration of Pat Brown. This period saw the great renumbering, as highways were unified under a combined legislative / sign route system (as opposed to the separate systems that existing previously). It also saw a tremendous expansion of the freeways as construction worked hard to meet the construction deadlines. The period ended with the passage of the California Environmental Quality Act (CEQA), the election of Ronald Reagan, and the Freeway Revolts.

Our interview is with Arturo Salazar, a retired District 7 Caltrans engineer and moderator of the Freeways of Los Angeles Facebook group.
