The Toowoomba Second Range Crossing (also referred to as the Toowoomba Bypass) is a 41 km (25 mi) grade separated bypass currently under construction to the north and west of Toowoomba, Queensland. Construction commenced in April, 2016 with an expected completion date in early 2019.
History
The city of Toowoomba is situated on a plateau on the edge of the Great Dividing Range. A defining chrematistic of the city is its high position on an escarpment of the range, which enjoys sweeping views of the Lockyer Valley below. [1] The existing range road was completed in its current alignment in 1939. This road has unfavourable road geometry including tight corners and a rate of climb as as high as 10.5%.[1] The Warrego Highway is a major Brisbane-Darwin highway that passes through Toowoomba and utilises the existing range road. The Gore Highway is a major freight corridor that travels from Melbourne (via the Newell Highway and the Goulburn Valley Highway) and terminates in Toowoomba. At present, up to 22,000 vehicles (including 2900 heavy vehicles) traverse the city’s CBD each day, passing through up to 18 sets of traffic lights.[2]
Planning
The need for a future second range crossing was first highlighted by Department of Transport and Main Roads in 1991.[1] In 1995, An Ove Arup Traffic Planning Study was completed confirming the need for a second range crossing.[1] In 1997, an alignment route option passing to the immediate north of Toowoomba City was identified in a Maunsell concept phase planning report. The traffic planning study determined that the bypass route has to be close to the city as 85 percent of Warrego Highway traffic is stopping in Toowoomba.[1] The proposed new alignment for the Warrego Highway commenced to the east, bypassing the Toowoomba City centre to the north and linking up to the Warrego and Gore Highways on the western side of Toowoomba.[1] The proposed alignment was 42.2km long; up to 40 bridge structures; 5 major interchanges; and twin 735 meter long three lane tunnels through the range crest.[1] Detailed planning of the project commenced in 2001 with the preferred alignment option ultimately refined by 2004.[1] In late 2005, the federal government announced funding of $10 million to advance the business case for the project.[1] Auslink committed $43 million towards further planning in 2008.[3][4]
Construction
In August, 2015 the Department of Transport & Main Roads awarded the contract to design, construct, and maintain the Toowoomba Second Range Crossing to Nexus Infrastructure, a consortium of the Plenary Group, Cintra, Acciona, Ferrovial and Broadspectrum.[2][5][6][7] Nexus was chosen for its design that employeed the use of a viaduct over the Toowoomba range (instead of tunnels) allowing the use of dangerous goods to utilise the bypass.[2] 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. Upon completion, the road will be tolled.[2]
Milestones
- 31 January 2014 - Federal and state governments agreed to underwrite $1.6 billion to build a tunnel[8]
- 21 August 2015 - The Nexus consortium awarded to finance, build, operate and maintain the motorway.[5]
- 15 April 2016 - Start of major construction
Timeline
- August 2015 — Contract awarded to Nexus Infrastructure[2]
- April 2016 — Construction commenced
- Late 2018[2]-mid 2019 — Scheduled completion. Originally scheduled for late 2018, but geological issues set back expected completion by 4 to 7 months.[9]
Route discription
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),[5] 24 bridges, six interchanges, nine creek crossings and one viaduct.[10]
The reference design, the basis for planning and environmental approval, features:[11]
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%
