Swing is usually rendered, at least on maps which focus on the thing 
_under_ the bridge rather than the thing over the bridge, as a filled 
black circle with a line extending from it, the line being the bridge 
over the e.g. canal.

Why does viaduct need a different rendering from bridge? Surely you know 
it's a viaduct because there's a train track running over it?
