The largest bridge and tunnel project in the history of Queensland, Australia, has reached two milestones. Spending on the scheme has passed AU$2 billion (US$820 million), coinciding with the second anniversary of the signing of contract documents.
Construction activity on the project has now reached its peak along the 20km corridor, said Main Roads minister Warren Pitt. A US$2.4 million time and cost saving has been achieved for the project's main structure - the 1.65km-long Second Gateway Bridge - following the use of match-casting.
Key project achievements to date include significant progress on the construction of the bridge, with five of the 10 deck spans completed on the 750m northern approach. The remaining concrete deck segments on the northern river bank will be installed by an 800t launching gantry. On the southern bank, the five deck piers have been constructed in less than five months, and the main piers in the Brisbane River are nearing their full height of 54m.
