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
• continuity of the New England Highway through bridges over the cutting.

In order to deliver the 41km road project, works were undertaken across three areas: east, central and west. Each area features major construction works critical to the overall road design.
