Originally constructed in 1939, the Leven River Rail Bridge had been gradually deteriorating due to exposure to wind and the saline environment. An analysis of options lead to recommending the complete replacement of the existing structure on a new southern alignment. The benefits of this option include an improved alignment, increased load capacity, certainty of outcome compared to rehabilitation and lowest lifecycle costs.
The project comprises of the design and construction of a 160 metre long railway bridge. This construction required the use of a false work bridge to build the bridge over water. The falsework consisted of steel beams spanning between timber pile bents, a timber deck and running boards. This system was designed to accept a 70t pile driving rig, a 30t pile driving excavator and a 160t crane.
