The TSRC is a bypass route to the north of Toowoomba, approximately 41 kilometres in length, running from the Warrego Highway at Helidon in the east to the Gore Highway at Athol in the west via Charlton. At $1.6 billion, it is one of Queensland’s highest priority road infrastructure projects and is funded on an 80:20 basis by the Australian and Queensland Governments.

The project’s scale, complexity and value meant that it was essential that Treasury’s Commercial Group, in consultation with the Department of Transport and Main Roads (TMR), conduct a rigorous and innovative procurement process to ensure commercial arrangements that delivered the best and most innovative technical solution for the money.

Following an interactive bidding process which allowed the State to drive enhanced technical and value for money outcomes (when compared with the reference design and tender requirements), and innovation in a number of key elements, Nexus Infrastructure consortium* was named as the successful bidder.

Nexus Infrastructure consortium was successful on the basis of its alternative (no tunnel) design solution, which was evaluated as offering best value for money to government. Their open-cut solution offers an alternative to a tunnel and will allow for heavy vehicles (including dangerous goods and over dimensioned vehicles) to be diverted from the Toowoomba city area – a key objective of the project.

With an estimated construction period of around three years, the contract is structured as an availability-based public private partnership. Using this model, the State is providing upfront government funding contributions during the construction stage of the project and ongoing service payments over the 25 year operation and maintenance stage, which will be dependent on performance.

The TSRC project has now transitioned from Treasury Commercial Group to TMR, which will manage the Nexus contract including the Project’s delivery, operation and maintenance phases. TMR will also oversee Nexus’ final design and community engagement activities throughout construction of the TSRC.
