‘Node-by-node’ – an Australian first

The award-winning Yandhai Nepean Crossing delivered by Seymour Whyte with VINCI sister company, Freyssinet, is opened to the public.

The landmark crossing in Penrith, western Sydney – with its 200m long unsupported span – is the longest single span shared user path bridge in the southern hemisphere. The crossing continues to draw crowds as an engineering marvel and has become a destination in itself.

An innovative and untested construction technique was developed to facilitate incremental ‘node-by-node’ launching of the steel truss. The ‘node-by-node’ launching is an Australian first – and is emblematic of the way the truss is supported and shifted at the node using jacks and rolling skates as the safest way to construct the truss over the river.
