Asking me how do I know that Eurovelo 3 is for tourism or bicycle trekking
is like asking me how do I know that Paris is the capital of France.
« Is there a sign saying that Paris is the capital of France? May be we
should remove that tag, don't you think?... »

You don't need sign post to have a route, do you have a sign post at the
intersection of those routes ?
I doubt that.

This is how the Wiki define a route:
« A *route* is a customary or regular line of passage or travel, often
predetermined and publicized. Routes consist of paths taken repeatedly by
people and vehicles: a ship on the North Atlantic route, a car on a
numbered road, a bus on its route or a cyclist on a national route. »

So to paraphrase this for road biking route :
« A road bicycle *route* is a customary or regular line of passage or
travel, often predetermined and publicized as such. Road bicycle routes
consist of paths taken repeatedly by road cyclist. »

And if you don't know then don't tag it and don't manage it.
