The spectacular Christopher Cassaniti Bridge (formally the Lachlan’s Line Bridge), located in New South Wales, is ones of Australia’s most innovative and striking new structures.
Commissioned by Landcom as part of the Lachlan’s Line Precinct development project connecting north-west Sydney suburbs Macquarie Park and North Ryde, this design is the first of its kind in Australia. Utilising a double helix arrangement with a varying diameter along its curving 178m length, at its narrowest it is 5.5m and reaches 7.8m at its widest. This incredible structure provides visual flair, safe accessibility, and excitement to the typically heavily traffic-congested area with a promotion of reduced car dependency, creating a significant positive impact to the surrounding environment.
Fabricated by New South Wales customer S&L Steel, Stirlings Performance Steels supplied around 100 tonnes of high-grade 2205 Duplex grade Stainless steel for the project. 2205 Duplex grade presented as an ideal material, thanks to its hybridised microstructural properties granting it superior mechanical properties to many forms of mild and Stainless steel, as well as offering advantages in durability and low maintenance due to its superior corrosion performance.
