The Yandhai Nepean Crossing, in Penrith, west of Sydney, has been recognised by the Sydney Chapter of the Australian Engineering Excellence Awards (AEEA).

Seymour Whyte General Manager, Southern, Steve Lambert said to be selected as one of the Sydney winners is a fantastic achievement and praised the efforts of all project partners in delivering this landmark project.

“The award recognises our team’s achievements in successfully weaving physical and social elements into both the design and construction aspects of the project to achieve a vision of making the bridge a destination in itself. The outcome has improved life for the local community while clearly demonstrating engineering’s benefits to society”.

“Congratulations to our team which includes our client and delivery partners for an outstanding feat of engineering. A special thanks to the Penrith community; we hope that this landmark is enjoyed for many years to come,” he said.

The Yandhai Nepean Crossing is a pedestrian and cyclist shared path bridge that crosses over the Nepean River at Penrith – one of the fastest growing areas of western Sydney. Before this crossing was built the community used the existing Victoria Bridge, 200 metres downstream, which is a road bridge with a narrow pedestrian footpath on the side.

Key scope for construction:

  • 258m long 3-span steel bridge, incorporating a 200m long unsupported main span (the longest single clear-span of any shared path bridge in the southern hemisphere) over the heritage-listed rowing course of the Nepean River.
  • Extensive temporary works for an innovative ‘node-by-node’ incremental bridge launch methodology (an Australian first), as well as two temporary river piers.
  • Bridge-approach retaining walls and civil works, including 130m long reconstruction of Punt Road.
  • 455m of shared path connecting into the existing footpath networks.
  • Adjustments to overhead and underground utilities, including Sydney Train’s overhead 66kV transmission line, and Endeavour Energy’s 11kV electrical mains.
  • Architecturally-designed feature lighting to complement bridge aesthetics and viewing platforms.
  • Landscaping improvements to fit with the new bridge and approaches, including land-use restoration after construction.

Engineering excellence was a key feature of this extremely complex project, and was successfully delivered through perseverance, team collaboration and extensive stakeholder engagement. This enabled the team to overcome several design, construction and logistical challenges.

Since its completion, the bridge now provides a safe and enjoyable means of crossing the Nepean River for thousands of people every day.
