Well, that might be correct if they're at layer -1 or +1 relative to a 
feature that hasn't been mapped yet.  A conversation with the original 
mappers (or a visit) should be able to resolve that easily.

Please tell me that you've actually visited these places to check that 
there is actually a bridge there (and not something best described as a 
tunnel), and note where the start and end of bridge actually are.  If I 
railway crosses a river and there's nothing indicating how it's a very 
useful indication that something's mapped incorrectly and needs 
checking.  Faking the data so that it doesn't look wrong actually 
removes very useful information from the map.
