Heavy vehicle road safety assessments
What has happened so far
In late 2023, the National Heavy Vehicle Regulator (NHVR) introduced a live map detailing heavy vehicle network constraints across Australia.
In March 2026, Council finalised the first round of assessments on council roads that require heavy vehicle access at an individual road level.
These assessments showed sections of roads, including a number of intersections across the region, don’t meet current safety requirements for heavy vehicles (including b-doubles and road trains).
Since then, Council has hosted community meetings across the region where this matter, among others, was discussed.
No changes have been approved yet.
Roads being assessed
Over 60% of Council’s road network has been assessed and safety concerns have been identified on the following roads:
Saleyard Drive – Nebo
The corner on Saleyard Drive is too tight to allow the swept path of the Type 1 and Type 2 Road Trains to remain within the travel lane as they turn the corner.
Braeside Road – Nebo (between Peak Downs Highway and Oxford Downs Sarina Road)
The stacking distance between the Aurizon rail line and Oxford Downs Sarina Road is 32m. This results in the 36.5m Type 1 Road Train and 53.5m Type 2 Road Train stacking over the rail line or within the through lanes of Oxford Downs Sarina Road.
Russel Park Road – Kilcummin
The stacking distance between the Aurizon rail line and Kenlogan Road is 32m. This results in the 36.5m Type 1 Road Train and 53.5m Type 2 Road Train stacking over the rail line or within the through lanes of Kenlogan Road.
Alpha Bypass Road – Clermont
The configuration of the intersection of Alpha Bypass Road/Rubyvale Road is not wide enough to allow the swept path of Type 1 and Type 2 Road Trains to remain on the road.
Airstrip Road - Nebo (between Braeside Road and Bowen Street)
Road widths do not comply for Type 1 and Type 2 Road Trains and Council has received safety and amenity concerns as a result of road trains travelling through town.
Tropic Street – Clermont (Jellicoe Street to Lavarack Street)
Recent traffic counts have identified no road trains travelling on this section of road over the past few years.
Next steps
Council will continue to assess heavy vehicle routes and seek expert advice on potential safety treatments at identified locations, including intersections at Russell Park Road and Braeside Road.
These assessments will require a combination of reports, expert advice, technical works, and your feedback. As well as the information we will provide, the assessments will include information from the Department of Transport and Main Roads (TMR), road users, and where relevant, third parties including Aurizon.
All of this won’t happen overnight, but it is a priority for council.
We appreciate residents, landholders, operators and industry representatives who are proactively engaging in this process.
Frequently Asked Questions
IS IT TOO LATE TO HAVE MY SAY?
The official feedback period has closed. However, Council is always interested in your thoughts. Feel free to email Sean Robinson at records@isaac.qld.gov.au or call Council’s Customer Service Centre available 24 hours a day, 7 days a week on 1300 ISAACS (1300 472 227) to discuss any matter, not just this one.
HOW SOON WILL WE KNOW WHAT IS GOING ON?
We don’t have the answer yet. As there are many entities to consider, reports to read, inspections to take place and your input to evaluate, it will take time. If you’d like to subscribe to updates, please do so here: https://mailchi.mp/5125dece7dd8/community-roads-updates
WHEN WILL WE HEAR SOMETHING?
We are currently conducting further assessments. Please join our mailing list for monthly updates: https://mailchi.mp/5125dece7dd8/community-roads-updates Even if we don’t have anything new to share yet, we will still let you know where we are at.
I’VE HEARD THESE CHANGES MEAN THAT I WILL HAVE TO FIND AN ALTERNATE ROUTE, IS THIS TRUE?
Once we have full assessments done, we will know what the next steps are.
WILL COUNCIL SHUT ROADS?
There are no intended road closures related to this issue at present. You may find road works/road crews etc on these routes for other reasons, but we will not be closing any roads without notifying you first.
HOW WILL I KNOW IF YOU ARE GOING TO CLOSE A ROAD?
If any change to road usage is deemed necessary, we will inform subscribers to updates via email. We will also post on our social media channels, relevant community pages, and Council’s website.
WHAT IF I WANT TO KNOW MORE?
We are always up for a discussion. Please contact Sean Robinson at records@isaac.qld.gov.au or call Council’s Customer Service Centre available 24 hours a day, 7 days a week on 1300 ISAACS (1300 472 227).
