In preparation for the completion of the Toowoomba Second Range Crossing (TSRC), Department of Transport and Main Roads engaged RMA as the lead engineers to undertake a preliminary route investigation focused on the movement of heavy vehicles east of the TSRC. The TSRC, a major infrastructure initiative designed to improve freight efficiency, required a strategic assessment of the Warrego Highway corridor between Helidon and Dinmore.
RMA was tasked with evaluating the highway’s capacity to support Performance-Based Standards (PBS) Level 3A, 3B, and 4A multi-combination vehicles.
Drawing on our deep understanding of transport infrastructure and commitment to delivering practical solutions, RMA investigated six key areas to determine the route’s suitability. These included a formation width analysis, curve speed assessments, climbing lane performance reviews, geometric route evaluation, operational constraints identification, and assessment of freight efficiency potential.
The investigation was guided by RMA’s focus on enabling safe and efficient freight movement, supporting regional connectivity, and delivering quality infrastructure. The findings provided critical insights into the route’s capability to accommodate high-productivity vehicles and informed future planning to align with the state’s freight strategy. RMA’s involvement in this project reflects its ongoing commitment to helping clients navigate complex transport challenges with clarity and confidence.
