TMR is upgrading and extending the guardrail on Carnarvon Highway during September 2022


The Department of Transport and Main Roads (TMR) is upgrading and extending the guardrail, and upgrading signage and line marking on the Carnarvon Highway (Mungindi – St George) at the Moonie River Bridge.

Upgrade works will commence from 12 September 2022 and are expected to be completed by late September 2022, weather and conditions permitting.

Early earthworks have been underway since 16 August 2022, in preparation for the improvements.

TMR will try to minimise traffic delays as much as possible by using single lane closures, traffic control and speed restrictions. Motorists should slow down, drive carefully and follow the instructions of traffic controllers and construction signage and allow up to an additional 10 minutes for their journey.

Works may restrict wide-load vehicle access and permit holders should check the TMR Conditions of Operation Database before travelling.
