That's about the weirdest bit of functional civil engineering I've ever seen. When I first saw the picture I thought the whole span moved up and down and wondered - What, do they move a Feris wheel back and forth underneath it? The wikipedia link helped clear that up. :-)
The [link|http://en.wikipedia.org/wiki/Forth_Bridge_%28railway%29|Forth Bridge] is neat too. My father has a book on it (I've not seen it).

Cheers,
Scott.
