Thank you for uploading this video! I just found this stretch of road on Google Maps today and I was instantly curious about it. From the research I have done, where Pine St. crosses this road, there used to be a bridge there, but it has since been torn down, and now it is a road built up with dirt. I have seen in some other videos about this, that the old Route 66 signs are still on this road where the exits would have been. I also heard that some of the locals didn't like driving this road because is was really dangerous because of the interchanges. Some of those are still there today, and you can see a bridge that doesn't cross anything on Google Maps.
