Replacing an aging timber bridge with a safer, stronger, and more resilient crossing for future generations.

Delivered for Southern Downs Regional Council, the Bourkes Road Bridge upgrade transformed a narrow single-lane timber structure into a durable two-lane crossing designed to improve traffic flow, increase load capacity, and significantly reduce long-term maintenance requirements.

Key project points

Improved Safety
The new two-lane bridge removes the need for motorists to stop or give way to oncoming traffic, creating a safer crossing for all road users.

100-Year Design Life
Built to provide long-term performance with no structural maintenance required under normal service conditions.

Greater Capacity
Rated to SM1600 loading, the bridge supports heavier vehicle movements while improving network reliability.

Flood-Resilient Infrastructure
The replacement structure provides a more durable solution capable of withstanding future flood events.

Local-Economic Benefits
Construction utilized local labor, plant, and concrete, supporting regional jobs and keeping investment within the community.

The location

The project is located on Bourkes Road at Elbow Valley near Killarney in Queensland's Southern Downs region. Situated approximately one hour south of Toowoomba and two hours south-west of Brisbane, the region is known for its rural communities, agricultural activity, and diverse natural landscapes.

‍

The bridge crosses the Condamine River, providing an important connection for local residents, businesses, and agricultural operations. Reliable transport infrastructure is essential to supporting the region's economy and everyday mobility.

Challenges

The existing bridge was a narrow single-lane timber structure in poor condition that no longer met the needs of the community. Southern Downs Regional Council required a replacement bridge that could improve safety, increase load capacity, and provide a longer service life.

‍

Delivering a cost-effective solution while reducing future maintenance obligations was a key project objective. The new crossing also needed to provide improved resilience against flood events and support the demands of a modern rural road network.

How we helped

InQuik delivered a 12 x 8.4m integral bridge solution rated to SM1600 loading, providing a robust replacement for the aging timber structure. By integrating the deck and abutments into a single system, the bridge eliminates the need for bearings and tie-downs, reducing future maintenance requirements and improving long-term durability.

‍

The modular construction methodology simplified installation and provided greater cost certainty throughout delivery. The completed bridge now offers a safer, stronger, and more efficient crossing that will serve the Southern Downs community for decades to come.
