The paper describes aspects of design and construction of what is believed to be the largest example of installation of precast concrete units by hydraulic jacking in Australia. The two separate carriageways of the Jacana Underpass, consisting of 18 precast inverted U shaped units each, were successfully jacked up to 110 m through materials consisting of residual clays and boulders through to medium to slightly weathered basalt beneath a busy arterial road, railway tracks and a suburban street without disruption to these overhead services.
