Wingecarribee Bridge is a three span, concrete-deck, dual steel box girder twin bridge on the Hume Motorway, approximately 134km south of Sydney.
In October 2017, a B-double travelling along the northbound carriageway lost control and crashed into the South-west corner of the Bridge before hanging over the side and bursting into flames. This resulted in significant heat and smoke damage to the bridge’s top and underside.
Between October 2017 and December 2017, emergency maintenance was undertaken to reinstate all damaged components of the bridge on the topside so that the Motorway could return to full operation. This project will close-out these remediation works by returning the girders to an acceptable pre-accident state.
Silver Raven has been engaged by TFNSW to help remediate the bridge from the damage to the carriageway.
- Vegetation clearing for access and establishment of site.
- Abrasive blasting of the heat affected box girder. Including lead paint removal.
- Scaffolding and negative airflow encapsulation installation to get access to the work areas and contain construction waste.
- Repainting of the heat affected box girder.
- Cleaning of the smoke affected box girders.
- Cleaning of the smoke affected areas inside and outside the bridge.
We have delivered another successful project to TFNSW to their specification and within the scheduled completion date which was greatly appreciated to the return the bridge to full service.
