Why not ask your question on the new OpenStreetMap Community Forum?

Using JOSM 5485 I have copied someone else's method for a tiny road bridge over a stream. I cut the road way, added in a new small section a few metres either side of the stream. I kept the keys of the original way; "highway=residential", "name=rue de boyaval" and a relation to walking route.

I added "bridge=yes" to the section. Every time I try to upload to openstreetmap I get a warning message saying "crossing waterway/highway" - which of course I do know, being a bridge.

What am I doing wrong?

It sounds like you just need layer=1

You can read more about the bridge and layer tags here:

Some users think that bridge/tunnel automatically imply layer=1/layer=-1 but this is not the case. They always have to be added, sometimes even with other values depending on additionally crossing ways.
