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.

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 9^th 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.

CA RxR 2.11: Route 2: In the Flatlands (Santa Monica and Los Angeles)CA RxR 2.11: Route 2: In the Flatlands (Santa Monica and Los Angeles)

Episode 2.11 of California Highways: Route by Route is the first of two episodes on Route 2. In this episode we explore the general history of all things Route 2: What was the second state route defined; what was legislative route (LRN) 2, what was Sign Route 2, and what is today’s Route 2. We focus on the flatland segment: From Santa Monica to the Glendale Freeway. We do a detailed exploration of the relationship of the Pacific Electric and Santa Monica Blvd; the history of Route 2 and US 66 — and the ever changing routing in Los Angeles and Santa Monica — and the whole story of the never-constructed Beverly Hills Freeway. The last episode of the season will complete our exploration of Route 2 by looking at Route 2 in the hills — the Glendale Freeway and the Angeles Crest Highway.

Note: I made one error in the show: I said the street in West LA was San Vincente. It is San Vicente (and I should know better — I grew up in the area and lived nearby on Darlington). Here’s the history of that name.
