Yandhai Nepean Crossing
This architecturally designed, award-winning $50 million project is part of the great river walk which provides the community with a safe, dedicated footbridge and cycle path, as well as panoramic views of the Nepean River and surrounding areas.
BG&E with Seymour Whyte provided the detailed design of the bridge that spans 200 metres over the Nepean River and featured a 10 metre deep steel Warren truss with plan geometry that included two reverse curves.
This challenging geometry required a complex construction approach on land. BG&E was engaged to deliver the project, and we achieved this by developing a unique and novel construction technique called ‘node-by-node’launching, which articulates supporting and shifting the truss at each node using jacks and rolling skates to ensure precise execution throughout the launch.
In Australia, our technical experts were the first engineers to use the incremental launch construction method many years ago and today, it remains one of the most effective.
