On 19 March 1932 the Sydney Harbour Bridge opened to the public. The event marked the end of almost a century of speculation and planning around a bridge or tunnel that would cross the harbour.
In 1922 the New South Wales Parliament passed the Sydney Harbour Bridge Act and preparation for the building got underway.
Construction began on the approaches to the span in 1923 and on the bridge itself in 1925. More than 1600 people worked on the bridge during its construction.
In 2017 more than 200 trains, 160,000 vehicles and 1900 bikes used the bridge every day.
