The key features of the Toowoomba Second Range Crossing include:

  • four lanes from Warrego Highway East Interchange to Warrego Highway West
  • grade separated interchanges at Warrego Highway West, Toowoomba-Cecil Plains Road and the Gore Highway
  • grade separated connections to Mort Street and Boundary Street
  • an approximately 30m deep cutting at the top of the Toowoomba Range, to ensure all classes of dangerous goods and heavy vehicles can be accommodated
  • an 800m long viaduct built east from the New England Highway, crossing over the existing Queensland Rail line
