+1
Bridge or culvert, one way has to be split (the road for bridge or the
stream for culvert) to identify the structure and one of the ways
needs a tag layer. It's true that the shared node is wrong here
excepted if it's a ford. It needs a local survey.
Same mapping issues can be found between roads and railways, railways
and rivers, etc
