For the final episode, the duo look backwards. Built over 100 years ago, the Old Ridge Route was the original inspiration for the Forgotten Roads series. Build originally to connect Bakersfield to Los Angeles, the Old Ridge Route was one of the first sealed roads in California. This route finds both Brian and Alex discovering a new part of the area close to their home. With buttery smooth dirt tracks and rough sealed roads, this journey is a fascinating look into some important California history.
