Episode 4.08 is the first of three episodes focusing on Route 12. We start by exploring LRN 12, which we visited before in our episodes on Route 8, for LRN 12 became I-8 between San Diego and El Centro. We then look at Sign Route 12 and Route 12, which are mostly the same route… except, of course, in the first segment where they differ in routing between Route 1 and US 101. Episode 4.08 focuses on the first two segments of Route 12, which covers the portions between Route 1 near Valley Ford or Jenner through Sebastapol, Santa Rosa, Sonoma, Napa, and into Cordelia. 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. As usual, we’ll cover historical routings, projects, and names along the route.

Welcome to Season 4 of CA Highways: Route by Route. Episode 4.01 is the first half of our exploration of Route 8. This episode covers the 8th State Highway, which became LRN 36 and later Route 194. It covers LRN 8, which ran from Ignacio (Novato) to Cordelia via Napa, and became parts of Route 37, Route 121, Route 12, and Route 29. We look at Sign Route 8, which became today’s Route 26. And lastly, we look at I-8 in San Diego, including its historical ancestor US 80. This includes former Route 209 to Point Loma, which was part of LRN 12 and possibly US 80, and former Route 109, which became the portion of Route 8 W of I-5 (and you’ll learn why that is not I-8). Episode 4.02 will pick up the story and explore the rest of I-8/US 80 between San Diego and the Arizona Border, including a discussion of the Imperial Highway.
