Here's the first half of episode 1.08: https://caroutebyroute.org/2023/02/18/carxr-1-08-highway-numbering-u-s-highways-part-i/
This episode explores the history and numbering of US Highways. We were planning to have an interview with Jim McDonnell of American Association of State Highway and Transportation..., but we're still working out the scheduling and I wanted to get this out. So when we get the interview, it will be Part II. You can listen to the episode at caroutebyroute.org, at Anchor by visiting https://anchor.fm/dashboard/episode/e1v664p , or search for California Highways Route by Route in your favorite podcaster app. Please share with your friends, and listen to some of our old episodes. Let me know if I'm getting better with the sound quality. Next month will be everything Interstate in California.
