Toowoomba Second Range Crossing

ACCIONA as a Design and Construct JV partner of the Nexus Infrastructure consortium, awarded with the contract to design and construct the $1.6 billion Toowoomba Second Range Crossing (TSRC).

In August 2015, Nexus Infrastructure was awarded the contract to design, construct, operate and maintain the 41km-long TSRC, connecting the Warrego Highway at Helidon Spa in the east with the Gore Highway at Athol in the west, via Charlton. We reached partial opening in December 2018 and the remaining section is anticipated to open around mid-2019.

Key Features

Key features of Design and Construct solution for the TSRC include:

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


ACCIONA and our partners recognise the significance of this Toowoomba Second Range Crossing in terms of regional economic development, employment and supply chain opportunities and training and skills development. Benefits to the region include:

  • The avoidance of up to 18 sets of traffic lights
  • Reduction of travel time across the range by up to 40 minutes for heavy commercial vehicles
