Construction

The Queensland Government appointed John Bradfield  on 15 December 1933 as consulting engineer to the Bureau of Industry who were in charge of the construction of the bridge. In June 1934 Bradfield's recommendation of a steel cantilever bridge was approved. The design for the bridge was based heavily on that of the Jacques Cartier Bridge

. Work sometimes continued 24 hours per day. The bridge has only one pier on the northern bank but two piers on the lower southern bank, one to bear the weight (the main pier) and, further to the south, one to prevent the bridge from twisting (the anchor pier). There was no need for an anchor pier on the northern bank as the bridge was anchored into schist
