John Job Crew Bradfield graduated BE from the University of Sydney with a Gold Medal in 1889 and ME with first Class honours and a University Medal in 1896. He joined the New South Wales Department of Public Works and in 1909 was promoted, assistant engineer. In 1912, he submitted designs for both a suspension bridge and a cantilever bridge to link Sydney and North Sydney. The cantilever design was accepted and Bradfield was promoted chief engineer for metropolitan railway construction, in which capacity he developed plans for a city railway. In 1924, he was awarded the University of Sydney’s first doctorate of science in engineering for his thesis entitled ‘The city and suburban electric railways and the Sydney Harbour Bridge’. He revised his plans for the bridge as an arch design, which was opened on 19 March 1932. Although there was some controversy over who was entitled to claim credit for the final design, the highway over the bridge was named in Bradfield’s honour. In 1934, he designed the cantilever Story Bridge over the Brisbane River, which was opened in 1940, with the highway over the bridge again named in his honour.
