Project Update

On 21 August 2015, the contract to finance, build, operate and maintain the $1.6 billion Toowoomba Second Range Crossing was awarded to the Nexus Infrastructure consortium in a 25-year availability-based public-private partnership.

Opening the Darling Downs for Business

Local residents and road transport operators who drive the Toowoomba Range Crossing have recognised the need for a second crossing for many years.

  • Contract value: Estimated $1.6+ billion
  • Client: Department of Transport and Main Roads
  • Contract style: Availability payment public-private partnership
  • Finance: Privately financed with government contribution
  • Procurement completed: August 2015
  • Delivery period: Late 2015 to late 2018
  • Maintenance period: 25 years from completion of construction

Now, with Federal Government committing funds to the project, the Queensland Government can deliver this much-needed piece of infrastructure. Funded on an 80:20 basis by the Australian and Queensland Governments, the Toowoomba Second Range Crossing will cost around $1.6 billion to build.

With an estimated construction period of around three years, the contract will be structured as an availability-based public private partnership. Using this model, the State will provide 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 project will deliver real benefits for the region by improving safety on the existing range crossing and across the Toowoomba CBD road network, enabling all types of trucks to bypass up to 18 traffic lights and significantly reduce travel times. It is also anticipated that, through improved freight movement, the crossing will facilitate an increase in economic activity in the region by $2.4 billion over 30 years. Local residents will also benefit from reduced noise, improved safety and improved local road conditions as traffic is removed from the main thoroughfare through town.

Project Benefits

The Toowoomba Second Range Crossing will deliver the following benefits:

  • Creation of up to 1800 full-time jobs during construction
  • Improved road and driver safety
  • Reduced travel time across the Range by up to 40 minutes for heavy commercial vehicles
  • Avoiding up to 18 sets of traffic lights
  • Relieved pressure on local roads by redirecting trucks away from Toowoomba’s Central Business District
  • Increased freight efficiencies
  • Enhanced liveability of the Toowoomba and Lockyer Valley areas

More information about the project can be found on the Department of Transport and Main Roads projects page.

Project Design

Nexus proposed design solution
Key features of Nexus’ proposed design solution include:

  • Four lanes (2 lanes each way) from Warrego Highway East Interchange to Warrego Highway West
  • Grade separated interchanges at Warrego Highway West, Toowoomba-Cecil Plains Road and Gore Highway
  • A grade separated connection to Mort Street
  • An approximately 30-metre cutting at the top of the Range will be constructed as an alternative to the tunnel solution as detailed in the reference design to allow all heavy vehicles, including dangerous goods and over-dimensional vehicles to use the TSRC
  • An 800m viaduct built over the existing Queensland Rail line
  • Continuity of the New England Highway through a new bridge over the cutting.

The Nexus consortium consists of Plenary Group, Cintra Infraestructuras Internacional S.L., Acciona Concesiones S.L., Acciona Infrastructure Australia, Ferrovial Agroman Australia and Transfield Services (Australia). The consortium brings together the ideal balance of global leaders in road construction and social infrastructure with a track record of successful local project delivery, and will combine with local Queensland-based resources.
