Warroo Bridge Replacement

Transport for NSW
In progress

Abergeldie, in collaboration with Transport for NSW, is delivering the Warroo Bridge Replacement. This three-span, 56.65m-long pretensioned concrete super-T bridge will replace the existing timber truss structure located over the Lachlan River on Warroo Bridge Road, 46km west of Forbes and 55km south-east of Condobolin. As the only major crossing connecting the Lachlan Valley Way to the Henry Parkes Way between these towns, the new bridge will improve access for wide vehicles and increase load capacity for heavy vehicles. Designed to be stronger and longer lasting, it will provide a smoother and safer ride for all road users.

Scope of works

The scope of works involves: 

  • Protection of existing services.
  • Bulk earthworks, including excavation and site preparation for bridge foundations and approaches.
  • Construction of piers and rock platforms within the waterway on both riverbanks.
  • Construction of abutments, wingwalls, and approach slabs.
  • Construction of the new reinforced concrete bridge with driven steel tubular piles, reinforced concrete columns, headstocks, and abutments supporting precast super-T girders.
  • Reinstatement works, including removal of all temporary working platforms from the waterway.

Innovation and complexity

The regional location of the project has presented challenges for procurement. From the outset, meticulous planning has ensured materials are sourced efficiently, and the team has actively fostered strong, collaborative relationships with local subcontractors and suppliers. This approach has also allowed the project team to build a strong sense of community with the residents of Forbes and surrounding areas, leaving a lasting positive impact on both our team and the local community.

Future-proofing the road network in regional NSW

The Warroo Bridge Replacement is a key investment in safer, more reliable infrastructure for the region. The new bridge has been designed with wider travel lanes and improved road approaches to support both local traffic and heavy vehicles. By lowering long-term maintenance needs and ensuring greater durability, it will provide lasting benefits for the community and the broader road network.
