Highway system

The Toowoomba Second Range Crossing (TSRC) is a highway construction project that will route heavy vehicle traffic around Toowoomba, Queensland. The route, being delivered by the Department of Transport & Main Roads and Nexus Consortium will be 41 kilometres (25 mi) long and will pass Toowoomba on its northern side, linking the Warrego Highway at Helidon Spa in the east and the Gore Highway at Athol in the west (via Charlton).

The Federal and Queensland governments are jointly funding the $1.6 billion project on an 80:20 basis. It is being delivered in a 25-year public–private partnership with the Nexus Infrastructure consortium.

Benefits[edit]

The Queensland Government says the benefits include:[1]

  • Avoids up to 18 sets of traffic lights in Toowoomba
  • Reduces travel time (by up to 40 minutes) and greater travel time reliability
  • Improved freight efficiency by redirecting up to 80% of heavy and super heavy commercial vehicles away from the Toowoomba central business district
  • Reduction in vehicle operating costs by ensuring a maximum slope gradient of 6.5% across the Toowoomba Range, a significant decrease from the existing range crossing which is up to 10%
  • Accommodate regional growth and increase productivity on the Darling Downs
  • Safer and less congested route than the existing range crossing

Route[edit]

The 41 kilometres (25 mi) route of the project is expected to include: 41 kilometres (25 mi) of bypass, a 30-metre cutting at the top of the range (instead of the twin, 700 metre, three lane tunnels in the reference design),[2] 24 bridges, six interchanges, nine creek crossings and one viaduct.[3]

The reference design, the basis for planning and environmental approval, features:[4]

Section Length Carriageway Speed Limit
Gore Highway and Warrego Highway West 13.25 km 2 Lane (single) 100 km/h
Warrego Highway West to Mort Street 9.15 km 4 Lane (divided) 90 km/h
Mort Street to Warrego Highway East 18.6 km 4 Lane (divided) 100 km/h

The planned maximum gradient is 6.5%

Construction[edit]

The contract to design, construct, and maintain the Toowoomba Second Range Crossing was awarded to Nexus Infrastructure, a consortium of the Plenary Group, Cintra, Acciona, Ferrovial and Broadspectrum.[7][8]

Milestones[edit]

  • 31 January 2014 - Federal and state governments agreed to underwrite $1.6 billion to build a tunnel[9]
  • 21 August 2015 - The Nexus consortium awarded to finance, build, operate and maintain the motorway.[2]
  • 15 April 2016 - Start of major construction

Timeline[edit]

  • August 2015 — Contract awarded to Nexus Infrastructure[10]
  • April 2016 — Construction commenced
  • Late 2018[10]-mid 2019 — Scheduled completion. Originally scheduled for late 2018, but geological issues set back expected completion by 4 to 7 months.[11]
