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.
