Far North Collector Road

Talis provided consultancy services for the civil design to prepare concept designs for the proposed Far North Collector Road, linking Illaroo Road to Moss Vale Road. Council had secured funding of $13.8M for the planning and construction of this road and is a priority for Council.

Talis’ scope of involvement included:

  • Detailed floodplain mapping and flood study;
  • Concept design for three bridge options to cross Bomaderry Creek;
  • Two concept design options for a signalised intersection with Moss Vale Road at the north;
  • Two concept design options for a roundabout at Illaroo road at the south;
  • 6Conceptual alignment of the Far North Collector Road, considering constraints such as flood levels and land acquisition; and
  • Detailed design of ten culverts.


Being a strategic route for the future of the Council, it has several constraints on the design parameters, as well as significant stakeholders. The alignment and intersection design had to consider the long term objective of the surrounding area, including:

  • Future planning for release of urban lots, which would see the design traffic exceed 9,000vpd in the future;
  • Future western bypass reservation and the Princes Highway, as part of the Nowra Bomaderry Structure Plan;
  • Flood levels for 5% AEP events surrounding Bomaderry Creek; and
  • Proposed options to retain existing dwellings, as well as options to limit necessary land acquisitions.

Talis considered all these factors in its Concept Design and resulted in significant design development and input from stakeholders including RMS.


The design included significant design development and client consultation, to achieve a ‘client focused approach’. The final Concept Design was pragmatic to Council’s needs. Talis is pleased to have received a score of 95% on the Council’s post project Performance Evaluation.
