The (limited) consensus on this page seems to be that we should abandon 
aqueduct= and viaduct= and just use bridge= for everything.

While it seems to me that this isn't current consensus or practice, it 
isn't necessarily nuts; I've already proposed bridge_type, and someone 
has said that it's easier to have alternative values for bridge, so 
instead of bridge=yes, we have bridge=motorised_swing, etc.

So why not bridge=viaduct, bridge=aqueduct?

Thoughts?
