it is about the distinction "property" and "feature". For example "embankment" can be a property of a road or railroad way (key: embankment), or it can be a feature of it's own: man_made=embankment Similarly, a road can be signed as being on a bridge (property bridge=yes) but the bridge can also be mapped on its own: man_made=bridge If you want to map a culvert without anything else, you could use man_made=culvert Cheers, Martin
