CA RxR 3.05p1: I-5: San Diego to Los Angeles (Part 1)

In this episode, we start 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 1, this part, starts with 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. We’ll finish the discussion in Part 2, where we look at projects along the route and names along the route. 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.

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

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.
