What exactly is "Line Roads" in cartouche?

What exactly is "Line Roads" in the Layers Panel of cartouche? Is it something I can ignore?

Looking at this spaghetti interchange that I have been working on, I have this "Line Road" right in the middle of it. I am assuming it is only because of some of the GPS tracks running through there. I just want to make sure that I don't have a problem in there somewhere.

Yes you can ignore this layer. Can't remember exactly what was said about this, but I believe it was for non-roads during the alpha, and has been depreciated since then, just never removed from cartouche.
