Pyrmont Bridge was originally made of wood. Opened in 1858 then demolished and reopened on stronger stone piles in 1902. Closed to car traffic in 1980s, today this swing bridge carries mainly pedestrians. You can also see the elevated monorail and the Sydney Tower at Centrepoint in the heart of the cities central business district.
A couple of people mentioned Darling Harbour as somewhere worth visiting on my visit to Sydney. After a couple of walks down to the area at different times of the day and evening I came away with a few photographs.
