Episode 4.04 is our second episode exploring 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. The previous episode covered post-1964 Route 9 (and the first segment of pre-1964 Sign Route 9) from Santa Cruz to Saratoga and then into Los Gatos, as well as all the 9th State Route and LRN 9. This episode (4.04) covers the pre-1964 Route 9 portions N of Saratoga: Sign Route 9 through Mountain View, Milpitas, and up through Hayward and the Castro Valley. This portion of Sign Route 9 became Route 85, Route 237, Route 17/I-880/I-680 (in portions) and Route 238.  The next pair of episodes will be covering I-10, with episode 4.05 covering the Santa Monica Freeway portion, and episode 4.06 covering the San Bernardino Freeway portion.

In this episode, we commence a 3-part exploration of Route 4. This episode starts with all things Route 4: The 4th state route, DOH and Legislative Route 4, and pre-1964 Route 4, finally setting on today’s Route 4. We talk about the LRNs that make up today’s Route 4: LRN 106, LRN 75, and LRN 24. We focus on the first segment of the route, from I-80 in Hercules to I-5 in Stockton. We talk about Route 4 in cities such as Hercules, Martinez, Concord, Antioch, Brentwood, the wetlands, and the Port of Stockton. We also talk about freeway segments, projects, and names along the route. The subsequent two episodes continue Route 4, with 3.03 focusing on the Stockton Crosstown Freeway.
