CA RxR 3.08: I-5: Whatever Happened to I-5W

Episode 3.08 continues our exploration of I-5 with a slight digression: A discussion about I-5W. In the late 1950s, I-5W was proposed as a spur route from I-5 running along what is today Route 132, I-580 (both the Tracy Diagonal and the former US 50 portion between the I-205/I-580 junction and Oakland/Berkeley), I-80 between Berkeley and near Vacaville, and I-505 between Vacaville and I-5. This short episode explores these pieces and their history. In Episode 3.09, we return to I-5 proper when we explore the former US 99W section of I-5 between Woodland and Red Bluff.
