Construction of the second Gateway Bridge: Brisbane, Australia

The Gateway Upgrade Project is a Queensland State Government initiative delivered by Queensland Motorways and the Leighton Abigroup Joint Venture. The project involves the upgrade of 20 kilometres of Brisbane's Gateway Motorway, with its signature feature comprising duplication of the 1.6km long Gateway Bridge, with a central main span of 260m. The approach structures to the main span are constructed using a pre-cast balanced cantilever method, while the main span is built using a cast in-situ balanced cantilever method. When complete, the second Gateway Bridge will join its twin in the top 10 longest of its kind in the world. The second Gateway Bridge includes the addition of a 4.25m wide pedestrian and cycle facility, making it a total 28m wide and requiring a different design and construction method to its existing counterpart. This paper will discuss detail the methodology and challenges involved in constructing the second Gateway Bridge.
