CA RxR 3.15: LA Metro Archives (Bonus)

With Episode 4.05, we turn our attention to Route 10. This first episode on Route 10 starts with an exploration of the 10^th route (the last ordinal route we’ll do), which was the Emigrant Gap Highway, and became the basis for LRN 37. This became part of the Lincoln Highway, then US 40, and is now part of I-80 from Sacramento to Nevada. We look at LRN 10, which became Route 198 from US 101 near San Lucas to Sequoia National Park. We then explore Sign Route 10 (which we discussed in our episode on I-5 in Los Angeles county), which ran from US 101A to US 101, later becoming Route 42 and US 101 Bypass, and eventually I-105 and I-5. Lastly, we turn to post-1964 Route 10, which is today’s I-10. In this episode, we focus on the first segment:  “From Route 1 in Santa Monica to Route 5 near Seventh Street in Los Angeles”, which is today’s Santa Monica Freeway. We look at its origins as Sign Route 6, which became Sign Route 26 along LRN 173, LRN 166, and LRN 171. We focus on LRN 173 (LRN 166 and LRN 171 were discussed in our episode on I-5 in Los Angeles county, as well as our episode on Route 6), which was Olympic Blvd. We explore the history of the Santa Monica Freeway segment, the experiments tried along this highway, some significant projects along this segment, and some significant names on this segment.

We will complete our exploration of Route 10 in Episode 4.06, which explores the San Bernardino Freeway: Its origins in LRN 26 and LRN 64 and the Ramona Airline. The history and strange intertwinings of the US highways that were signed on Route 10: US 60, US 70, and US 99. The transition to I-10 and the story of Route 10S. Lastly, we’ll cover projects and names on the segment.
