The Dinmore to Helidon Spa section of the Warrego Highway falls below modern safety standards, with a high average fatal crash rate of between three and 10 times that of a contemporary motorway standard. In addition, there is low flood immunity along this section of the highway, which significantly affects freight productivity and access for passenger movements.
The Warrego Highway is Queensland’s principal east–west freight route. The section between Dinmore and Helidon Spa is the gateway to western Queensland and connects Darwin and Melbourne to the Port of Brisbane.
Strong freight growth to the Port of Brisbane, together with population growth, particularly around Ipswich, will place greater pressure on the highway.
