Episode 3.09 continues our exploration of I-5 with the segment from Sacramento to Red Bluff, which primarily incorporates the former LRN 7 / US 99W routing between Woodland and Red Bluff, and a new routing that roughly followed LRN 238, then LRN 50 and LRN 232 between Sacramento and Woodland (near former Sign Route 16 and Sign Route 24). We talk about this history of this segment, as well as some discussion of historical routings in Natomas, Woodland, Williams, Willows, Corning, and Red Bluff. Our exploration of I-5 finishes in Episode 3.10, where we explore the former LRN 3/US 99 segment between Red Bluff and the Oregon Border.

Episode 3.08 continues our exploration of I-5 with a slight digression: A discussion about I-5W. In the late 1950s, I-5W was proposed as a spur route from I-5 running along what is today Route 132, I-580 (both the Tracy Diagonal and the former US 50 portion between the I-205/I-580 junction and Oakland/Berkeley), I-80 between Berkeley and near Vacaville, and I-505 between Vacaville and I-5. This short episode explores these pieces and their history. In Episode 3.09, we return to I-5 proper when we explore the former US 99W section of I-5 between Woodland and Red Bluff.

Next up in our exploration of I-5: the segment between the I-5 / Route 99 split and where I-5 meets former US 99W (now Route 113) in Woodland. Generally known as the “Westside Highway”, this was mostly a completely new routing for I-5 along LRN 238, although some portions paralleled former US 50 between Stockton and Sacramento, and Sign Route 16 between Sacramento and near Route 113 in Woodland/Yolo. As usual, we cover the history of the route, naming, and projects. Subsequent episodes will be looking at (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.

In this episode, we continue our exploration of I-5, the central spine of California. We’re splitting the discussion over 6 episodes, some of which are two-parters. This first episode (a two-parter) looks at the former US 101 segment, from the Mexico Border to Downtown Los Angeles. Part 2, this part, looks at the projects along this segment of I-5, as well as some of the more significant names. Go back to part 1 for a discussion of all things 5: Maritime Highway M-5, the 5th state highway, Legislative Route 5, Sign Route 5, and then I-5. For I-5, we look at the history of the route, and the pieces that led to first the US 101 Bypass and then I-5 in this area. Subsequent episodes will be looking at (3.06) from Downtown LA to Wheeler Ridge, where Route 99 splits, including the Ridge Route; (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.

CA RxR 3.01: Route 3: Through the Mountains of JeffersonCA RxR 3.01: Route 3: Through the Mountains of Jefferson

September 29, 2024| Daniel| 0 Comment| 10:29 am

Welcome to Season 3 of California Highways: Route by Route. We promised that the season would start in September, and we’re making it by the wire. Season 3 covers Routes 3 through 7; this is the first episode covering Route 3, which is in Northwest California near Weaverville and Route 299. In this episode, we talk about all things “three”: The third state route, Legislative Route 3, Sign Route 3, and finally the current Route 3. For the current Route 3, we talk about the history of the route, projects currently ongoing on the route, and some naming along the route. We even have a digression on the proposed Interstate 3. We also talk about the state scenic highway system, and how routes earn the golden poppy. The next three episodes will be focused on Route 4.

CARxR 1.11: Highway NamingCARxR 1.11: Highway Naming

May 28, 2023| Daniel| 0 Comment| 4:27 pm

In our penultimate episode of the season, we explore highways and their names. Tom and Daniel discuss how highways got their names in the past, as well as how highways are named today through the legislature. You’ll see a discussion of historical names, destination-based names, and memorial names. We’ll also explore auto trail names, as well as some of the more notorious names that highways have been given. Lastly, listen until after the end credits for a discussion about an aspect of naming that people often forget.

Our last episode in the season will explore the organizations related to the state highways. We’ll then have a short hiatus while we write season two, and then we’ll start exploring the California state highway system, route by route.

CARxR 1.09: Highway Numbering: Interstate HighwaysCARxR 1.09: Highway Numbering: Interstate Highways

March 25, 2023| Daniel| 0 Comment| 1:04 pm

In this episode, we continue our exploration of numbering of state highways by turning our attention to the Interstate Highway system. This system, started in 1956, uses the red, white, and blue shields. It is the third episode in a four part miniseries on highway numbers in California. In this episode we talk about the history of the Interstate Highway system, how the Interstate Highways are numbered, the history of California’s chargable interstates (i.e., highways that counted towards the federal 42,500 mile limit), the history of California’s non-chargeable interstates, some interstate submissions that were never approved, and we opine about some of the most common questions about California interstates.

There is no interview. We’re going to move the interview segments into separate bonus episodes, owing to the difficulty of obtaining and scheduling the interviews.

The remaining episode in this miniseries will explore the numbering of and the history of California’s signed county route system.
