The Sydney Harbour Bridge was opened in 1932 and is the widest steel arch bridge in the world.
The design for the Sydney Opera House was chosen after the New South Wales Government conducted a competition in the late 1950’s. Danish Architect Jorn Utzon’s vision was the winning design. Unfortunately in 1966 Jorn Utzon resigned from the project because of disagreements with the Government. Jorn Utzon died in 2008 without ever returning to Sydney to see in person the amazing Opera House he designed.
