Yorke Highway Realignment

A proposal to realign 5 kilometres of the Yorke Highway near Pine Point sought to accommodate the proposed Rex Minerals Hillside copper mine, as the existing road is within the safety blasting zone of the mine. The design was developed in two phases – a planning investigation to determine a preferred alignment clear of the blasting zone, followed by the detailed design of the preferred alignment.

Tonkin Consulting developed the initial concept plan using contours obtained from aerial photogrammetry. A number of route options were analysed based on the Digitised Terrain Model before selecting the preferred alignment, and identifying a corridor which was then surveyed in preparation for detail design.

In addition to realignment of the Yorke Highway, modifications were required to the Ardrossan-Minlaton Road as well as an upgrade to Sandy Church Road, which is to be used as the main mine site access road.

The realignment of the Yorke Highway and re-routing the Ardrossan-Minlaton Road was undertaken in consultation with Department of Planning, Transport and Infrastructure.

Drainage conditions were also assessed and significant drainage infrastructure was designed.

The new design also catered for B-doubles carting grain to the Port Giles export terminal.

Tonkin Consulting facilitated development of the new design through the DPTI processes culminating in final plans receiving all the necessary DPTI approvals.
