In this episode, we complete our exploration of Route 4, covering the segments from Stockton and Route 99 through Angels Camp, and then on over the Sierras to Route 89 near Markleville. This includes segments that go through Gold Country, as well as the Ebbetts Pass segment that includes some very steep grades. Along the way, we look at the history of the route in these areas, projects along the way, and naming of the route. As always, we conclude with a discussion of this segment of the route after the credits. Next up: The first of six episodes (some with two parts, making it really eight episodes) covering Interstate 5. Episode 3.05 looks at the former US 101 portion from the Mexico border to downtown Los Angeles.
