Toowoomba Second Range Crossing


The department is delivering a second range crossing that takes heavy vehicle highway traffic around north of Toowoomba rather than through it.


The 41km-long bypass route will run from the Warrego Highway at Helidon Spa in the east to the Gore Highway at Athol in the west, via Charlton.


The department is delivering an alternative crossing of the Toowoomba Range for all classes of heavy and super heavy vehicles to improve freight efficiency and driver safety, relieve pressure on Toowoomba’s roads, and enhance liveability for the city’s residents.


Nexus Infrastructure Pty Ltd


This project is being delivered under a Public Private Partnership (PPP) arrangement, with an indicative total cost of $1.606 billion. This includes an Australian Government contribution of $1.137 billion, with the balance to be funded by the Queensland Government.

The TSRC will result in the following benefits to the region and the State:

  • supporting up to 1800 direct and indirect jobs during the design and construction phases
  • improved road and driver safety
  • reduced travel time by up to 40 minutes and greater time travel reliability
  • avoiding up to 18 sets of traffic lights
  • relieved pressure on Toowoomba's local roads by redirecting heavy vehicles away from Toowoomba's Central Business District
  • removal of over-dimensional and all classes of dangerous goods vehicles from the suburban streets of Toowoomba
  • increased freight efficiencies
  • enhanced liveability of the Toowoomba and Lockyer Valley areas. 

The TSRC will bring $2.4 billion over 30 years of economic and productivity gain for business and industry to Toowoomba. When completed, the crossing will significantly increase the movement of freight along the national road network.

With an estimated construction period of around three years (from late 2015), the project will be delivered using a Public Private Partnership delivery model. Under this model, the State Government 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 TSRC will be a toll road. Tolls for the TSRC will not be finalised until closer to the opening of the road, expected in late 2018. Further consultation with industry and the community will be undertaken before the finalisation of a toll structure and toll tariffs.

The selection of Nexus as the preferred proponent was based on an extensive evaluation process which included financial, technical, commercial and legal criteria.

Nexus is a consortium of global leaders in road construction and public infrastructure, combined with Queensland based resources with a successful track record of local project delivery.

Nexus consists of:

  • Plenary Group, financial advisor and investor
  • Cintra, investor
  • Acciona Concessions, investor
  • Acciona Infrastructure and Ferrovial Agroman, construction joint venture
  • Broadspectrum, operations and maintenance provider. 

Key features of Nexus' proposed design solution include:

  • 4 lanes (2 lanes each way) from Warrego Highway East Interchange at Helidon to Warrego Highway West at Charlton
  • grade-separated interchanges at Warrego Highway West, Toowoomba-Cecil Plains Road and Gore Highway
  • grade-separated connections to Mort Street and Boundary Street
  • a 30m-deep cutting at the top of the Toowoomba Range as an alternative to the tunnel solution as detailed in the reference design
  • an 800m-long viaduct built over the existing Queensland Rail rail line, connecting the Lockyer Valley and the Toowoomba Range escarpment
  • continuity of the New England Highway through a new bridge over the cutting. 

The original reference design for the TSRC included tunnels at the New England Highway on the top of the Toowoomba Range. The Request for Proposals process encouraged tenderers to develop innovative design solutions. The evaluation of responses received included alternative value-added design solutions, such as a cutting of about 30m deep at the top of the Toowoomba Range. 

The Nexus design incorporated the open cut solution. The tunnel solution as detailed in the original reference design did not allow for the passage of some dangerous goods and over-dimensional heavy vehicles, while the proposed open cut solution provides a better outcome.
