Project overview

What is the Toowoomba Second Range Crossing?

The Toowoomba Second Range Crossing is a 41 kilometre heavy vehicle bypass route to the north of Toowoomba. When finished, it will connect the Warrego Highway at Helidon Spa in the east to the Gore Highway at Athol in the west via Charlton.

The project is the largest Australian Government commitment to a single road project in Queensland’s history and will ensure freight efficiencies, and significantly improve driver safety and community amenity by removing heavy vehicles from Toowoomba’s CBD.

As the centrepiece of major economic development taking place in south-western Queensland, the road will create a safer, faster and more efficient route for connecting freight to major ports and markets.

Who is Nexus Infrastructure?

Nexus Infrastructure was awarded the contract to design, construct, operate and maintain the Toowoomba Second Range Crossing in August 2015. Nexus Infrastructure comprises a consortium of global leaders with extensive experience in road construction and social infrastructure, plus a track record of successful local project delivery.

Who is Nexus Delivery?

Nexus Delivery is the Construction Joint Venture of Nexus Infrastructure, and is responsible for the design and construction of the project. Nexus Delivery consists of Acciona Infrastructure Australia and Ferrovial Agroman.

Who is funding the Toowoomba Second Range Crossing project?

Nexus Infrastructure has entered into a Public-Private Partnership with the Australian and Queensland Governments, who are jointly funding the delivery of the $1.6 billion project on an 80:20 funding split arrangement.

This cost covers the full design and construction of the toll road, including road and pavements, cuttings, structures and underground services, plus a 25 year operation and maintenance contract.

What are the benefits of the Toowoomba Second Range Crossing?

The Toowoomba Second Range Crossing will:

  • improve road and driver safety
  • reduce travel time across the Toowoomba Range by up to 40 minutes for heavy commercial vehicles
  • avoid up to 18 sets of traffic lights
  • relieve pressure on local roads by redirecting trucks away from Toowoomba’s CBD
  • increase freight efficiency
  • enhance liveability in the Toowoomba and Lockyer Valley areas.

What are the key features of the Toowoomba Second Range Crossing?

The key features of the Toowoomba Second Range Crossing include:


What are the project’s working hours?

Work hours are from 6am to 8pm for general construction activities and 6am to 10pm for maintenance activities. Most works will still be undertaken during standard construction hours from 6:30am to 6:30pm, Monday to Saturday.

As part of constructing the Toowoomba Second Range Crossing, Sunday and out-of-hours works may also occur. Directly affected residents will be notified prior to Sunday and out-of-hours works commencing.

Construction time frames and scheduled activities may change due to weather conditions, site conditions or unforeseen circumstances.

What impacts will the community experience during construction?

During construction, the community can expect:

  • increased vehicle and machinery movements onsite and on local roads
  • short delays and traffic changes on local roads
  • increased noise, dust and vibration associated with the use of heavy equipment and machinery. For the safety of onsite workers, reverse beepers cannot be switched off
  • construction works between 6am and 8pm with some maintenance, night works and additional works out-of-hours.

We thank you for your patience while we undertake works to complete the project. For more information contact the Community Relations team on 1800 198 878 or email

Why do dates change?

On a project the size of the Toowoomba Second Range Crossing there are many moving parts. As a design and construct project, dates and time frames can change as the project progresses and construction methodologies are informed by design updates. Time frames are also dictated by site conditions, construction and delivery schedules, weather impacts and project priorities.

We’re working hard to ensure the community is aware of construction activities ahead of time and every effort is made to minimise the impacts of these activities. Make sure you’re always in the loop by regularly visiting our website for construction notifications and traffic impacts as well as the controlled blasting schedule. You can also connect with us on Facebook, and share updates with your family and friends.

The Toowoomba Second Range Crossing is a design and construct project. What does that mean?

As a design and construct project, the Toowoomba Second Range Crossing’s initial concept through to completion is a streamlined process delivered by one team. It also means design is completed before and during construction. While this collaborative process promotes innovation and efficiency, it also means that construction dates and time frames can change as the project progresses and construction methodologies are informed by design updates.

When will the Toowoomba Second Range Crossing be completed?

We are expecting a delay of around four to seven months for the completion of the Toowoomba Second Range Crossing project.

While the project is progressing well overall, the delay is due to a complex geological issue under one of the embankments in the Ballard area.

The issue has resulted in us changing the construction methodology and building the foundation of the embankment from a deeper level. As a result, extensive additional earthworks are now required in a small section of the project.

All other scheduled activities for the project will continue as planned.

We will continue to keep the community informed about these works, and provide updates as the extent of delays and construction impacts are known.


Where are the entry and exit points for the Toowoomba Second Range Crossing?

The Toowoomba Second Range Crossing is a heavy vehicle route designed to increase freight efficiency.

There will be six entry and exit points:

Local residents will be able to use these points in conjunction with the local road networks to leave the TSRC and access their destination.

Our website has a number of maps which give more detail on each of the above interchanges.

Is the Toowoomba Second Range Crossing going to be two lanes in each direction?

The road will be four lanes (two in each direction) from the Warrego Highway east interchange at Helidon Spa to the Warrego Highway west interchange at Charlton. It will then be two lanes (one in each direction) from the Warrego Highway west interchange to the Gore Highway at Athol.

Will there be noise barriers along the Toowoomba Second Range Crossing once the road is operational?

Nexus recently completed an operational noise assessment in accordance with the Department of Transport and Main Roads’ Road Traffic Noise Management: Code of Practice 2014 (CoP). The CoP provides guidance and instruction for the assessment and management of the impact of road traffic noise.

The assessment involved a three-dimensional noise model which predicts future noise levels by using digital topography information, anticipated future traffic volumes and speed, road gradient, road surface, height and location of residential dwellings and other buildings, and the noise reducing effects of natural noise attenuation (such as dirt mounds).

Calculations conducted in accordance with the CoP predict the project will be in full compliance with operational noise requirements. This means no noise barriers are planned for the Toowoomba Second Range Crossing.

Will there be pedestrian access along the New England Highway at Mount Kynoch once the Toowoomba Second Range Crossing is completed?

Yes. Pedestrian access will be provided as part of Toowoomba Second Range Crossing project works alongside the New England Highway at Mount Kynoch.

Toowoomba Regional Council is working with the Department of Transport and Main Roads to develop long term pedestrian access on the New England Highway outside the Toowoomba Second Range Crossing project area.

What allowance has been made for emergency stopping bays in the final design?

There will be 20 emergency truck stopping bays spaced along the Toowoomba Second Range Crossing alignment, as well as an additional bay with access from either direction of travel between the Mort Street interchange and Boundary Street. This will allow heavy vehicles to check load security and brakes prior to descent (eastbound) and after the ascent (westbound) of the Toowoomba Range. There will also be a heavy vehicle de-coupling bay and rest area on Nass Road that will be accessible from the Warrego Highway west interchange.

Is there going to be an on-ramp/off-ramp onto the New England Highway from the Toowoomba Second Range Crossing?

No. Our design of the Toowoomba Second Range Crossing is based on the reference design provided by the State Government which details the alignment, interchange locations, on- and off-ramps and traffic configurations for the corridor. There isn’t provision as part of the project for on/off ramp facilities at the New England Highway. The closest point of access to the Toowoomba Second Range Crossing will be via the Mort Street interchange, about 4.5km away.

However, the Toowoomba Second Range Crossing has been designed so that on- or off-ramps may be added at any stage in the future.

Where can I see a detailed map showing the location of the project?

Please take a look at our interactive map. If you zoom right in and view in ‘street’ mode, it’s easy to see how the current road network interacts with the Toowoomba Second Range Crossing.

Does the Toowoomba Second Range Crossing include an off-ramp to the Toowoomba Wellcamp Airport?

No. Construction of an off-ramp to Toowoomba Wellcamp Airport was not included in the State Government’s reference design and does not form part of the Nexus design solution. Motorists on the road bypass will be able to use the Toowoomba-Cecil Plains Road interchange to access the Toowoomba Wellcamp Airport.

How will the Warrego Highway east interchange affect the local road network around Helidon Spa?

The median break at the  intersection of the Warrego Highway, Postmans Ridge Road and Twidales Road at Helidon Spa will be closed as part of the Warrego east interchange works due to the safety impacts of merging and weaving traffic. The Department of Transport and Main Roads is developing a design to build U-turn loops either side of the intersection to keep access open after the Toowoomba Second Range Crossing is built.

The intersection plan involves building a U-turn loop, allowing westbound traffic to exit the Warrego Highway at Helidon Spa and travel on the loop road to rejoin the Warrego Highway eastbound before turning left into Postmans Ridge Road or continuing on towards Brisbane.

Another U-turn loop for Warrego Highway traffic travelling eastbound will mean access remains open to Twidales Road.

Is there any provision for animals to go under or over the Toowoomba Second Range Crossing?

The Toowoomba Second Range Crossing features a number of fauna-sensitive design elements. This includes fauna passages, furniture and fencing to support biodiversity and allow safe fauna movement.

Six fauna passages will be positioned within fill embankments and areas of dense or significant vegetation habitat across the alignment. Fauna furniture, such as rocks, logs, ropes and poles, will also be used to provide refuge from ground predators and increase connectivity.

For more information on the project’s environmental commitments visit our environment page.

Why were fauna movement underpasses selected as opposed to land bridges?

Fauna movement underpasses were selected due to TSRC project footprint constraints. There are six fauna movement underpasses on the project.

Passage for arboreal fauna (fauna adapted for living and moving around in trees) between habitats will be through fauna underpass culverts. Culverts will include vertical hardwood refuge poles at the entry and exits, and a horizontal hardwood refuge pole bridge which extends through the culvert. These refuge poles help fauna move safely and escape from predators if needed.

Box culverts are being used on the TSRC because arboreal fauna prefer wider access and more light.

In areas where bats have been identified, culverts which are more than 1.5m high will include mesh for roosting.

Fauna fencing has also been included along sections of the alignment to assist in funnelling species into fauna movement underpasses, and will be used alongside the underpasses to deter and help prevent animals entering the operating road environment.

These environmental design elements comply with the Department of Transport and Main Roads Fauna Sensitive Road Design Manual Volume 1 and 2.

How much will the toll road cost to drive on?

The Toowoomba Second Range Crossing is a Federal and State Government funded toll road designed to increase freight efficiency and significantly improve driver safety and community amenity by removing heavy vehicles from Toowoomba’s CBD. The location and pricing of tolls will be managed by the State Government and is not currently part of the scope being undertaken by Nexus.

Who is the Operations and Maintenance (O&M) arm of Nexus Infrastructure?

Nexus Operations, consisting of Broadspectrum, is responsible for operating and maintaining the Toowoomba Second Range Crossing for 25 years after completion of the toll road.

Toowoomba Second Range Crossing - Cranley to Athol section

How much of the Toowoomba Second Range Crossing is opened?

The Toowoomba Second Range Crossing is open to traffic between Cranley on Toowoomba’s northern edge and the Gore Highway, 25km west of the city, providing 24m of new road.

When will the whole Toowoomba Second Range Crossing open?

A geotechnical issue has delayed the opening of the TSRC until around mid-2019, following completion of remediation works on the affected embankment at Ballard, road surface formation, paving, line marking and installation of guardrails and signs. We look forward to celebrating the full road completion with a fantastic community event mid-2019.

How advanced is the remediation work?

The substandard material below the embankment has now all been removed and reconstruction of the embankment from foundation level is well underway.

Why did you decide to open part of the road?

Nexus advised that the remainder of the project that is not influenced by the geotechnical issue would be complete by the original Date for Completion of 3 December 2018. This provided the opportunity to open the 24km-long section of road between the Mort Street interchange at Cranley and the Gore Highway interchange at Athol to traffic.

What are the benefits of the partial opening for road users?

The partial opening will provide benefits for the community through access to alternative routes between the Gore Highway at Athol and Warrego Highway at Charlton, and between Charlton and north Toowoomba, destinations north of Toowoomba.

How can drivers access the partially opened sections?

The partial opening means drivers can use the TSRC between the interchange with Mort Street at Cranley in Toowoomba’s north and the interchange with the Gore Highway at Athol, 25km west of Toowoomba.

They will also be able to use the western interchange with the Warrego Highway at Charlton, providing connectivity between the Toowoomba Central Business District, Warrego Highway at Charlton, Toowoomba-Cecil Plains Road – for access to Wellcamp Airport – and the Gore Highway.

Will the partially opened sections be tolled?

No tolls will be charged until the whole road is open between Helidon Spa in the Lockyer Valley east of Toowoomba and Athol west of Toowoomba, a distance of 41km providing an alternative to the existing range crossing in Toowoomba.

Why don't you charge a toll for the opened sections?

The toll gantry is located east of the Mort Street interchange so it is outside the opened section of the TSRC. The opened section does not provide an alternative crossing of the Toowoomba Range, which is the key objective of the TSRC.

When will you announce tolls?

Tolls for the TSRC will be announced closer to the opening of the whole road in mid-2019.

What are the key features of the partially opened sections?

  • Four lanes (two lanes each way) between Cranley and Charlton, a distance of 9km
  • Two lanes (one each way) between Charlton and Athol, a distance of 15km
  • Grade-separated interchanges at Cranley, Charlton, Wellcamp and Athol
  • Access to the Nass Road truck stop and decoupling pad at Charlton
  • A grade separated connection to Boundary Street
  • Sections of road where the centre line has been widened to provide a bigger gap between vehicles travelling in opposing directions to reduce the risk of head-on crashes

Will there be any restrictions on the use of the newly opened road?

The newly opened section is a designated B-Double Route, providing access to the New England Highway for travel north from Toowoomba.

Completion of the current upgrade on Griffiths Street by Toowoomba Regional Council, expected in the coming weeks, will complete the permanent link between the TSRC and New England Highway at Harlaxton.

B-Doubles using this route from 8 December 2018 will be detoured via Jellicoe Street until the Griffiths Street upgrade is complete.

Type 1 Road Trains can use the opened section between the Warrego Highway interchange at Charlton and the Gore Highway at Athol.

The TSRC provides access to the newly opened truck stop and decoupling pad on Nass Road at Charlton through traffic signals installed at the Warrego Highway-Nass Road intersection.

This will enable operators to “decouple” (reconfigure) vehicles and temporarily store the trailer on the pad before travelling east of Charlton, or to check their loads and take a break.

How can people find out more about how to use the newly opened section of the Toowoomba Second Range Crossing?

Precast deliveries

Will the community be notified when deliveries take place?

Yes. We will notify the community in advance of road closures, detours and traffic impacts via and our traffic page.

Will the community be advised of alternative routes for road closures during precast deliveries?

Motorists will be advised to seek alternative routes when precast deliveries significantly impact the road network. Please visit or our traffic page. Traffic management will be in place for all traffic detours.

Where are the Super T girders and deck units made?

Precast beams (deck units and girders) are manufactured offsite to minimise disruption to nearby residents and transported via preapproved haulage routes. Deck units and Super T girders are being manufactured by Wagners Precast and Enco Precast.

Who is transporting precast beams?

Precast beams are being transported by ALE.

What volume of precast beams will be transported?

500 Super T girders and 600 deck units are being transported for use across the project alignment. 22 of 24 structures across the project require precast beams.

How will precast beams be transported?

Super T girders will be transported in convoys and the longer Super T’s require two prime movers to travel up the Toowoomba Range.

What’s a Super T?

Super T girders were developed in Australia in the early 1990s for bridge construction. Precast bridge girders used on the Toowoomba Second Range Crossing will be up to 37m long and weigh around 90 tonnes each, with 33 cubic metres of concrete used to make each girder.

How do I find out more about precast deliveries?

Please visit the traffic page for more information, or call the Nexus Community Relations team on 1800 198 878. You can also sign up for eNews updates via our website.

How many Super Ts are transported during each Toowoomba Range closure?

The delivery of precast materials needed to construct bridges across the alignment is a huge operation. We aim for multiple deliveries during each intermittent Toowoomba Range closure, however this is dependent on permits, the construction stage of each bridge being built, the size and weight of the precast material, and weather conditions.

Intermittent closures of the westbound up lanes of the Warrego Highway, Toowoomba Range, occur between midnight and 4am and last for approximately one hour at a time. Click through for current traffic impacts.

Controlled blasting

What is controlled blasting?

Controlled blasting is a safe and precise method for loosening hard rock which is used alongside conventional construction methods such as excavators and scrapers. For more information click through to the earthworks and controlled blasting factsheet or take a look at our controlled blasting schedule.

What does controlled blasting look and sound like?

Controlled blasting involves:

  • a momentary increase in noise, dust and vibration from the blasting and associated machinery activity. Blasting itself takes only a number of seconds
  • changed traffic conditions. Depending on the proximity of blasting to local roads, a temporary hold and release of traffic may occur while the blast is operational
  • motorist delays of up to five minutes during hold and release activities
  • traffic control to safely direct motorists through the work area.

You can see a video of our controlled blasting here.

Will emergency access be maintained during controlled blasting activities?

Yes. Working directly with emergency services is a necessary part of the controlled blasting process and access will be maintained at all times. Should emergency services require access, controlled blasting activities will be put on hold until there is no longer an emergency situation.

Where can I find a schedule of controlled blasting activities for the project?

You can find the controlled blasting schedule, including locations, timing and impacts here.

Haulage routes

Where can I find information about approved haulage routes for the project?

For information about haulage and the approved routes in use, please visit the project haulage page. Additional or alternate routes may be used occasionally depending on traffic conditions, the needs of the project, emergency situations or other unforeseen events. Traffic controllers will be used, as required, to ensure safe vehicle movements along local streets.

I have a question or concern about driver behaviour on the project’s haulage routes. Who do I contact?
