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.

Welcome to the first season of California Highways: Route by Route. This first season will be establishing the background listeners will need for our subsequent route by route podcasts. We’ll start with a history of the state highway system. We’ll then explore how highways are numbered in the state. Lastly, we’ll look at how highways are named, and some of the organizations involved with state highways.

This first episode explores the start of the state highway system. We’ll start with the humble beginnings with the first routes defined by the legislature, and then go into the routes defined by the first three bond acts. We’ll also explore the Good Roads movement, and we’ll have a special interview with Adam Prince of Gribblenation.

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

March 25, 2023March 25, 2023| DanielDaniel| 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.

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.
