Construction started under three different contracts : the southern approach and the Stanley-Vulture Street interchange were done by Thiess Bros; the bridge was built by  Transfield Constructions and McDougall-Ireland built  the South Brisbane superstructure. Work began in 1968 and was completed at the end of 1972.

 ‘The bridge forms part of the Riverside Expressway. A box casting yard is visible on the narrow riverbank below the Kangaroo Point Cliffs at the south abutment. A gantry crane was used to stack the completed boxes along the riverbank. A floating crane was used during construction of the bridge. Inner city buildings are visible from the construction site, with Mount Coot-tha and the Victoria Bridge in the background.’ (State Library of Queensland)
