Hello,

Who is your source for this, please?

I’ve just had a look at official data and way 34320346 is officially named "Hoefijzerstraat - Rue du Fer à Cheval", and so are the addresses of all the buildings here.
This word means "horseshoe" and is the name of this street because of its shape.
I unfortunately don’t have any Mapillary picture to prove it but just to be sure I had a look at a famous street view website and the street sign confirms official data.

My opinion is that the person who asked for this change is not reliable and that it should not have been changed without checking.  Please undo your changeset.
