Call it what you will, but the Sydney Harbour Bridge really is Australia\u2019s most well-known badge of recognition. Here’s some little-known fast facts about the coathanger.<\/strong><\/p>\n

On the 19th of March 1932, an estimated crowd of 300,000 to a million people lined the shores around Sydney to witness the unveiling of the momentous bridge. Considering the trials and tribulations that it took to finally open it’s gates, it’s no wonder why the Sydney Harbour Bridge attracted such crowds.<\/p>\n

The first suggestion to build a bridge connecting the northern and southern shores of the harbour dates as far back as 1815. Put forward by a convict and architect, Francis Greenway, the construction of a connecting bridge was not to be taken seriously until decades later. It was in 1900 that the Government invited design submissions for the bridge, although all submissions were deemed unsatisfactory. Renewed interest in the Bridge following the end of the first World War saw the design by Dr. J C Bradfield finally accepted in March 1924. It took 1,400 men eight years to build the Sydney Harbour Bridge and cost the government 4.2 million Australian dollars. Beyond the general history, here’s some lesser-known facts about Sydney’s most iconic landmark.<\/p>\n
