Copied from [ticket:9304#comment:26]:
> Well, highways should only start or end at the node sharing with the `man_made=bridge` and the highway on the bridge (inside the area) should have the same layer value.
Same is true for `man_made=tunnel`.

So we have two cases:
* A highway sharing a middle node with a man_made bridge or tunnel seems to be an error in most (all) cases.
* A highway sharing a start or end node with man_made bridge or tunnel and inside the area of the man_made needs the identical `layer=*` and a `bridge=*` resp. `tunnel=*` (not value `no`)
