So again I have to ask what the bonuses would be--some bridges have tolls, many, like the Pont du Rialto, do not (also the Golden Gate Bridge did not charge visitors on foot last I checked; just motor vehicles). Many bridge wonders suggested above are simply pretty bridges with some history; hardly the tourist draws like the Pyramids or Statue of Liberty for example. The best bonuses I can think of them for them would be Great Engineer point generation; hardly something awesome. There are plenty of actual world wonders that have more history and more to them than just nice statuary decoration.
