Sydney Harbour Bridge, Dawes' Point to Milson's Point, suspension design 1912 ... for tramway, vehicular and pedestrian traffic only. [and] (Cross section near tower)1912
Civil engineer John Job Crew (JJC) Bradfield proposed several designs for a bridge across Sydney Harbour, including a suspension bridge in 1912, and a cantilever bridge later that year. In 1922 he recommended the arch bridge we know today. While it is unclear who designed the final Sydney Harbour Bridge, it was probably a collaboration between Bradfield, the consulting engineer for Dorman Long & Co of Middlesbrough, England (the successful tenderers for construction of the bridge), and other Australian engineers working on the project.
