Sydney Harbour Bridge

Sydney Harbour BridgeCall it iconic, symbolic, the gateway, the most famous, distinctive, landmark or whatever, but the Sydney Harbour Bridge is really Australia’s most well-known badge of recognition.  Oh yes!  The locals call it ‘The Coathanger.’

When it was officially opened on 19th March 1932, an estimated crowd of between 300,000 and a million people lined the shores around the harbour to witness it.

Construction work on the Sydney Harbour Bridge began in 1924. The first suggestion to build a bridge connecting the northern and southern shores of the harbour came as far back as 1815. The suggestion was put forward by a ‘convict,’ and architect, Francis Greenway. It was only in 1900 that design submissions were invited with the approved design, by Dr. J C Bradfield, accepted in March 1924.

There is still an ongoing debate (heated at times) as to which bridge is the model for the Sydney Harbour Bridge. The two contenders are the smaller Tyne Bridge in Newcastle-upon-Tyne, England and the Hell Gate Bridge in New York, USA.

Sydney Harbour Bridge Climb:  To get an absolutely stunning 360° view of Sydney and the Blue Mountains you have to take the Bridge Climb. This guided climb started in 1998 with tours, of 12 to 14 people, leaving every 10 minutes or so. The round trip takes roughly three and a half hours. There are also twilight and night tours when you can catch a fabulous sunset or the city as she lights up.

At around US$200, the price is a bit steep (pun intended).
