Hello, I would consider each situation from #3 to #9 here as a bridge.
Here’s why. If there had never been a railway, the road would be where it is now, and it is perfectly flat and aligned with the houses nearby (implicitely level=0 and layer=0 in OSM). On the contrary, the embankment is an artificial structure that has been built to raise the railway and make it fly over the road. I tried to have a look at Infrabel’s Open Data portal, but couldn’t find a list of their bridges so far. They manage about 4,800 bridges and it would make sense that our data match theirs. Cheers.
