Description & Facts: Take a tour of Sydney Harbor Bridge in Sydney, Australia -- part of the World's Greatest Attractions travel video series by GeoBeats. The Sydney Harbor Bridge is an iconic part of Sydney's skyline and Australia's image in general. Nicknamed "The Coat Hanger," this steel through arch bridge is among the world's tallest and widest of its kind. The bridge connects Sydney's central business district and the North Shore. The expanding and contracting of the steel, due to heat or cold, makes the bridge sway slightly. The bridge weighs around 52000 tons, and is held together by millions of hand-driven rivets. It has been the site of many celebrations of national pride, including the 2000 Olympics and countless New Years Eves. The bridge has rail, automobile, bike and pedestrian traffic, and continues to be a tourist and lookout attraction.
