BATEMANS BAY BRIDGE
Snapshot
Located in a coastal town in southern New South Wales, the Bateman’s Bay Bridge demolition project was undertaken as a collaborative arrangement with the principal contractor, John Holland. Due to the project’s complex nature, a global team of industry leading engineers was engaged to design a unique demolition methodology, encompassing both the superstructure and substructure.

Project Scope
The original Batemans Bay Bridge comprised ten spans with a central steel vertical lift truss, which at maximum height reached 23 metres. A custom designed and fabricated submersible diamond wire saw used to cut concrete piers of varying diameters from 2.3 metres up to 3.6 metres. Each span was then lifted as a single unit using multiple Self-Propelled Modular Transporters (SPMTs) positioned on an 54 metre x 21 metre barge. The barge relocated the bridge span to a specially constructed temporary jetty where the SPMTs drove it to the processing pad where it was deconstructed.
Project Highlights
- Innovative demolition method allowed for bridge spans to be removed in entirety in single lift.
- Over 90 percent of materials recycled and 100 percent steel salvaged.
- Project delivered during peak of state COVID border restrictions.
