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.

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.

Our I-5 exploration continues, with a focus on the segment of I-5 from the US 101 split in Downtown Los Angeles to the Route 99 split in Wheeler Ridge. This episode, Part 1 of 3.06, after a recap on LRN 5 and Sign Route 5, focuses on the history of I-5 from Downtown LA (DTLA) to and through the Newhall Pass. We explore the history of LRN 4 and LRN 161, the timeline of freeway construction to and through Burbank, the history of Route 5S (Colorado Blvd), and a dive into the history of routings through the Newhall Pass and in Saugus. We also talk about the Interstate number submissions for I-5, and have some updates on the projects we discussed in Episode 3.05p2. Our special guest this episode is Sydney Croasmun of the Ridge Route Preservation Organization. Sydney brings her expertise to our discussion in Part 2, when we’re going in detail over the Ridge Route. Part 2 also discusses projects and naming in this section, especially the history of the “Grapevine” name. Subsequent episodes will be looking at (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.

January 12, 2024January 12, 2024| DanielDaniel| 0 Comment| 5:00 am

Episode 2.06 of California Highways: Route by Route continues our exploration of Route 1 by exploring everything about Route 1 from Pacifica, just N of the Tom Lantos Tunnels near Montara (in San Mateo Couny) to and through San Francisco up to the Golden Gate Bridge. This includes communities such as Pacifica, Daly City, and of course, San Francisco. As always, we go over the history of this segment of the route, the history of the route through various communities , the freeway plans, discuss relinquishments, names, and some current plans (although there’s not much in the relinquishment or plans area). As part of the freeway plans in the area, we include a discussion of the freeway revolt and some broader plans for San Francisco. Looking forward, episode 2.07 will continue our exploration of Route 1 with something Route 1-adjacent: The Golden Gate Bridge.
