can we have an abandoned road territory?

I was thinking about the dark part of the map again, and I was wondering if it'd be possible to have an abandoned road?

Hypothetically, humans would've come to teekon years ago to start construction, but the state comes in and says "hey you can't do that. this place is reserved for wildlife". Or the construction team would lose funding for the road somehow. Either way it'd be abandoned and left to erode.

I can understand why this wouldn't be allowed. The guidebook says there's no human involvement and teekon is untouched. I just see this as an exception cause humans aren't involved anymore, and characters wouldn't know who put the road there. And I just think it'd be a neat change in scenery :)
