Episode 4.06 continues our exploration of Route 10.  Episode 4.05 covered the first segment of Route 10: The Santa Monica Freeway between Route 1 and the I-5/US 101 junction. This episode, 4.06, covers the second segment of Route 10, from US 101 to the Arizona Border. Along the way, we explore the former I-110 segment, Route 10S, and do a deep dive into the US highways that shaped this segment of I-10: US 60, US 70, and US 99. We explore the historical routing of those highways across this segment. We also look at some of the names on the highway, and current projects along the highway.

In the next episode, 4.07, we'll turn our attention to Route 11. We'll start by exploring LRN 11, and then look at the original Sign Route 11. This was originally tied closely with the development of US 66, and became today's Route 110. We'll also talk about the current Route 11.
