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.For more information and additional links, visit this show's page at its forever home on CARouteByRoute.
