Gatton Heavy Vehicle Decoupling Facility

The permanent Gatton Heavy Vehicle Decoupling Facility allows heavy vehicle drivers to reconfigure their combinations to conform to national regulations before continuing their journey east.

When the Toowoomba Bypass opened in 2019, Type 1 road trains and Performance Based Standards (PBS) Level 3A networks were extended to the eastern side of the Gatton interchange. A temporary short stay Road Train Transfer Facility was developed at the Gatton interception site on the Warrego Highway to help accommodate trailer transfers until a new permanent facility could be built.

In March 2021, construction will be complete (weather permitting) on the permanent Gatton Heavy Vehicle Decoupling Facility for heavy vehicle drivers to reconfigure their combinations to conform to national regulations before continuing their journey east. Once the permanent facility is complete, the temporary facility will revert to its previous function as an interception site.

All Type 1 road trains and PBS Level 3A combinations must conform to complying B-doubles or otherwise permitted combinations (for example, PBS A-double) before continuing east of the Gatton Heavy Vehicle Decoupling Facility.

It is an offence for Type 1 road trains to travel east of the Gatton Heavy Vehicle Decoupling Facility.

Users must leave the site clean and tidy at all times. The site will be monitored via CCTV and will be clearly sign-posted advising drivers that penalties apply for dumping onsite.
