Apparently there's an "expressway" bypass of Pittston, PA, part of it US 11, part of it undesignated. There's a stub end at its southern end. Where would it have gone? Would it have fed into anything? Will it ever get built?

Seems that it was to continue to downtown Wilkes-Barre and perhaps beyond.
