On the webcam thing
I'll drive past this on the way home tonight:

That pic's from an angle which belies the true shape of the bridge, BTW.

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).
[link|http://www.instacam.com/showcam.asp?id=ALVND&size=S|Here]'s a webcam at an elementary school a few miles from me. It's a bright sunny day but cool (a windy cold front came through yesterday).
Cheers, Scott.

The Newport Bridge has the up-down thing.
It's welded into the down position now, though. It's a mile or so upstream of the Transporter.

There's one just like that in Vallejo CA
had to radio to get it raised when I took my boat from Napa back down to SF Bay

I've seen bridges like that.
The old Ryde bridge in Sydney was like that, although it doesn't lift anymore. Caused an interesting problem when they started a ferry service up the river - solved by using low profile catamarans.
A number of bridges up and down the NSW coast used to have lifting sections. I think the one at [link|http://en.wikipedia.org/wiki/Batemans_Bay|Bateman's Bay] (no picture) still does.
We have a few opening bridges right in Sydney, though. One is the [link|http://en.wikipedia.org/wiki/Pyrmont_Bridge|old Prymont bridge] (now a pedestrian walkway) over the mouth of Darling Harbour. It has a turning section. Another is the Spit Bridge across [link|http://en.wikipedia.org/wiki/Middle_Harbour|Middle Harbour]. It has a tilting section and has set opening times because the road across is a major thoroughfare.

tilts up from one end
the others go straight up. Kelowna (interior BC) has a floating bridge with a tilt-up span as well. These things are dangerous becaues the road bed on the tilting section is open mesh steel, like a seive. Two wheeled vehicles tend to "squirm" when crossing them.

Amazing.
I've heard of elevated canals in Holland, too.
