The council listing is secondary in this - I've walked down these streets, they are about 7m wide and have "street" in their name. Pedestrian streets having these characteristics are routinely tagged like this all over Ireland and have been since the beginning of the project. In addition, I've just been shown a photo of the entrance from Patrick Street. It carries, as I mentioned above, the usual no vehicles sign and has a plate naming the street a "Pedestrian Zone" between 11:00 and 18:00 Monday-Saturday. There's really no more to say here.
