I accept they are not actively under construction! Is that what the tag is meant to mean? It's quite possible they will never be finished.
The streets directly to the north which have more houses on them appear paved with kerbs to me. Also one lane of the dual carriageway is not continuous around the corner, suggesting it is unfinished.

I'm not massively invested in the concept though, and have absolutely zero local knowledge. Feel free to change them if you are sure.
