Pile foundation and approach embankment design for Coronation Drive Viaduct in Brisbane

The design and construction of the Coronation Drive Westbound Viaduct was a component of the Hale Street Link Alliance project. This paper presents the geotechnical issues and the importance of obtaining sufficient geotechnical information highlighting the key challenges arisen from the concept to detail design developments for the viaduct foundations. The experience gained from the westbound approach embankment in limiting the long term settlement and its interaction with the new sewer rising main is also discussed.
