https://www.openstreetmap.org/note/4072832 brought to attention that there seems to be some connectivity issues with this or some related edit.  I'm not sure which edits introduced it but this was mentioned.
It looks like the upper and lower decks of the bridge are connected which is a bit problematic.  TBH, OSM is not very well suited for overlapping layers so having the two layers slightly offset is better than having them connected but of course it's not exact.  What are your thoughts?
