ACCIONA Infrastructure as part of Acciona Ferrovial Joint Venture (AFJV), has been engaged to design and build the new bridge over the Clarence River at Harwood, located on the Pacific Highway, in New South Wales.
Location: Harwood, NSW, Australia
Our role: Design and construct
Infrastructure: Design and construction of 1.5km single deck bridge
Project value: Part of the overall AU$4.36 billion Woolgoolga to Ballina Pacific Highway upgrade
Estimated completion date: End 2019
Construction of the new bridge involves:
The project is part of the larger AU $4.36 billion Woolgoolga to Ballina Pacific Highway upgrade and is jointly funded by the state and federal governments.
Once complete, the upgrade will improve road safety, reduce travel times and increase transport efficiency.
Piling work on the foundations for the new bridge has started and will continue through to the end of 2017.
Land cranes and support vehicles will move materials from the land to the temporary jetty on the river. Supporting marine vessels will transfer the materials from the temporary jetty to the main barges on the water. The main barges will support two to three cranes to insert the piles into the river.
The first permanent pile for the new bridge was successfully driven in April. The test pile had four steel pile casings welded together and was vibrated and hammered about 65 metres into the ground. The test pile confirmed the data from the geotechnical investigations and confirmed the piling depths required to build the bridge. The pile passed through marine clay and gravel and into a harder layer of rock at about 65 metres. The test pile is one of 117 permanent piles for the bridge.
