I noticed that too. My guess is that it was closed well before 2012 as I don't seem to remember this road ever being open to through traffic despite traveling through the area somewhat frequently around that time. Either that, or Way Road was technically open but under a low maintenance regimen by the county. There are a lot of those types of roads in the Lost Nation state game area region.
Interesting that apparently it was never specifically marked as "closed", at least not in any of the NBI listings, then it just up and disappears as of the 2012 listing.
