Hey Piagno, you're absolute right.
My problem is that the authorities haven´t yet published (or I didn´t found it) the route of the new "Hauptstrasse 2". Even though I know the approximate new route but not the exact one.

A living street can not be set up on a primary (https://www.fedlex.admin.ch/eli/cc/1979/1961_1961_1961/de#art_2_a Abs 5). So primary is wrong, but no primary is also wrong.

Do you have an idea how to map the current state?
