The Sydney Harbor Bridge is largest single span arch bridge in the world. The sweeping span over Sydney's famous harbor is 503 meters long, 134 meters high and 49 meters wide. Flanked by four towering concrete and granite pylons, it is the crucial center piece of Sydney's transport network. The weight of the steelwork alone totals 52,800 tons and includes an extraordinary six million rivets. The bridge officially opened on Saturday 19th March 1932 and has become an enduring international symbol of Sydney.
