Dawson Highway—Roundstone Creek Bridge Replacement

We are replacing the ageing timber Roundstone Creek Bridge on the Dawson Highway to increase safety, reliability, capacity and improve flood immunity.

The bridge was built in 1945 and is one of the few remaining timber structures on the Dawson Highway.

We are delivering a project to replace the existing bridge with a new concrete structure.

This project is part of an ongoing program of works to replace timber bridges in the Fitzroy District and will support future growth in the agricultural and freight industries by enabling increased freight connectivity across Central Queensland while ensuring a safer driving experience for all motorists.

During works, we will ensure strategies are in place to minimise impacts to nearby residents and road users.

In addition to replacing the existing timber bridge, the nearby intersection with Glenmoral Roundstone Road will be upgraded to accommodate B-Doubles.

The Roads of Strategic Importance (ROSI) initiative will also provide a $6 million investment for the Roundstone Overflow project. These works will improve existing culverts as well as install new drainage structures to improve flood immunity.
