[OSM-talk] Ditches

[John F. Eldredge]

If you are going to tag every culvert in the world, you are talking about adding millions of additional entries to the database.  This seems rather unnecessary.

Honestly, it sounds like some kind of tag for the node would be
appropriate. I would support creating a junction and tagging it
"culvert=1", for small cases where "bridge=1" is overkill. (Like the
image provided).

That would remove ambiguity, and clarify exactly what's happening.
