Bridges

Robert Bird Group (RBG) was engaged by the CBGU JV to design a new pedestrian and cycle bridge over the rail corridor providing a connection between Joe Baker Street, adjacent the new Boggo Road Station and Kent Street, adjacent the Princess Alexandra Hospital and the nearby bikeway as part of the Cross River Rail Project.

The bridge consists of a cable stayed steel box girder segment with two steel box girder approach segments.

This paper describes the design process and the adoption of international standards to supplement the AS 5100 series of Australian Standards.

Further the systems adopted to achieve the required 100-year design life for the bridge as described.

The effect of the construction sequence on the design of the bridge is described.
