Oh the neighborhood groups were not happy when this plan was announced. It is kind of silly to restore a street grid without actually opening the streets. With most authorized traffic going directly to/from the VSC anyway, it’s not even clear who will drive on most of these “streets”.
In the end, I’m actually quite happy with it, because this whole area will effectively be one big pedestrian zone. FiDi would benefit from a lot more car-free streets. In any other major world city, a historic district with narrow winding roads — like most of FiDi — would be car-free or at least very limited-access (authorized delivery vehicles only, etc.) I’ve been all over Europe, and when this is done, it works well. It’s frustrating that NYC is still so stubbornly car-oriented when most residents don’t even own a car.
