Wybong Creek Bridge - Yarraman Road

The Yarraman Road Bridge project replaced a flood prone causeway with a new 102.3 metre concrete bridge, providing a reliable all weather crossing over Wybong Creek. Delivered as part of the Mangoola Coal Continued Operations Yarraman Road Upgrade, the project improves safety, connectivity and network resilience while supporting future growth in the Wybong region. MLEI delivered the bridge engineering from initial investigations through to detailed design and construction support.
