The Department of Transport and Main Roads is undertaking work to improve the Castlereagh Highway (St George - Hebel) near the intersection with and Noondoo - Mungindi Road.

Work will involve:

Realigning the curve to improve sight distance.
Installation of a light structure to improve visibility; and
Updating signage and line marking.

Work is being undertaken between 6am and 6pm up to five days a week and is expected to be completed in mid-2026, weather and conditions permitting.

We will try to minimise traffic delays as much as possible by using traffic control, speed restrictions and single lane closures. Motorists should slow down, drive carefully and follow the instructions of traffic controllers and construction signage and allow up to an additional 15 minutes for their journey.

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