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.
