This is what I’ve heard about the Lincoln Highway, it can be in 3-4+ places in the same general area. There was a PBS show that I watched a few months ago, though I think the show itself was about 10 years old, where people were trying to follow as much of the Lincoln Highway as possible. There was one place where a dirt road was right next to another dirt road and both of them were parts of the highway.
This might the show I saw.
