Last week Brady Marine & Civil’s Harwood team completed the last land driven pile for the new bridge over the Clarence River at Harwood, which is the longest bridge on the Woolgoolga to Ballina upgrade.
The new bridge will be about 20 metres east of the existing bridge, 1.5 kilometres long and four lanes wide. It will be safer for road users, eliminate the need for motorists to stop when the bridge is raised for maritime users and it will support regional development.
The Australian and NSW governments are jointly funding the $4.36 billion Woolgoolga to Ballina Pacific Highway upgrade. Roads and Maritime Services Pacific Highway Project Office and Pacific Complete are working together to deliver the 155 kilometre upgrade.
The new bridge is being delivered by Acciona Ferrovial joint venture under a design and construct contract. Brady Marine & Civil is a subcontractor for Acciona Ferrovial joint venture and responsible for:
- Driving 2 metre and 2.4 metre large-diameter steel tubes on land (52 piles) and in the river (65 piles)
- Excavating and concrete plugging of the driven tubes
- Forming and casting of submerged pile caps in the river.
We have installed 113 of the 117 piles for the new bridge. To install the marine piles we are using our new construction barge ‘Rebecca Lily’ to drive piles with single lengths up to 53 metres. We have also imported a IHC S500 piling hammer from Singapore that weighs in excess of 100 tonnes.
We are working collaboratively with Roads and Maritime Services, Pacific Complete and Acciona Ferriovial joint venture to deliver the bridge over the Clarence River which is a key part of the upgrade.
Brady Marine & Civil’s work is expected to be completed in March 2018.
