А что здесь за amenity=townhall? И smoking=no

Split this part of avenida on separate forward and backward ways (from Plaza E. Mitre to Las Heras).

To avoid misleading pedestrian crossing from Plaza to Gutierrez (avenida has sidewalk=both).

Is barrier=yes needed for buildings here?

"shop or kindergarten?"

Оставить тут какую-то одну подходящую дорогу.

Судя по всему тут с адресами мешанина ..
Вроде Ушестенская - длинная улица, но тут и Новогрудская встречается в домах. Вроде еще опечатка в addr:street. Кто местный?

What is the correct street name here?

Like in highway's name = "重慶北路一段152巷"
Or like in a addr:street = "重慶北路三段152巷"

First of all I'm not an expert here, but:

building-address here have "addr:street=萬大路322巷27弄"

At the same time, the nearest street is "name=萬大路322巷37弄"

Is it in general ok for Taiwan or some fancy building addr:street<->street's name match should happen?
