Causality 61: West Gate Bridge

30 November, 2025

CURRENT

Planned for nearly a century, when the time came to build a permanent link across the Lower Yarra River, a relatively new style of bridge, the box-girder, was chosen. Using new computer technology assisting the engineers to design a bridge that was too complex to calculate by hand, and using a unique lifting strategy promised time and cost savings. Ultimately though when the pieces didn’t fit together in the air, their attempts to make them fit, didn’t work. We dive into what went wrong on Australia’s largest ever industrial disaster.
