The Batemans Bay Bridge replaced the existing steel lift bridge with a new precast segmental box girder bridge. The $274 million project delivered improved connections in and around Batemans Bay for motorists, freight, river users, pedestrians, and cyclists. The new bridge was built using prefabricated concrete elements, installed from the piers toward the centre of the spans using the balanced cantilever method.
CaSE & Pike Design were engaged by John Holland to design the propping system that ensured the stability of the bridge during construction. The system was notable for its simplicity, with a clear load path and elements that were easy to assemble, dismantle, and re-use on subsequent piers.
Following the successful completion of the new bridge, CaSE & Pike Design were also engaged by John Holland to assess the existing bridge during its demolition, one span at a time. This included the design of special temporary works to maintain the structural integrity of the bridge and its foundation throughout the demolition process. CaSE’s approach focused on ensuring a clear load path and sufficient robustness, delivering a fit-for-purpose methodology developed in close collaboration with the John Holland team.
