Kilcoy Creek Bridge replacement project


The Department of Transport and Main Roads has started construction works to replace the timber bridge over Kilcoy Creek on the D’Aguilar Highway just east of Kilcoy. The timber bridge will be demolished and replaced with a 15.25 metre wide 2-lane concrete bridge which includes a dedicated pedestrian pathway. Kilcoy Creek Bridge on the D’Aguilar Highway is a key freight route network linking the lower part of the Sunshine Coast and Moreton Bay region with the Darling Downs region and is the only remaining timber bridge on the route. This new concrete bridge will ensure the freight network is catered for into the future.

Detailed design work is complete. Funding was allocated in 2018 for the upgrade and construction is underway and expected to be complete by mid-2020, weather and construction conditions permitting.


The new 15.25 metre wide concrete bridge will improve safety and capacity for pedestrians, cyclists and motorists travelling on the D’Aguilar Highway. This project will improve freight productivity by removing the current load restraints at the bridge. Improvements include increasing the bridge width from 8.5 metres to 15.25 metres, providing a dedicated pedestrian pathway on the bridge, reducing the inspection and maintenance costs associated with maintaining the existing timber bridge and removing current load constraints.


The $5.88 million upgrade is jointly funded by the Australian ($2.94m) and Queensland ($2.94m) Government.

Project info

The Department of Transport and Main Roads has received funding to replace the timber bridge on the D’Aguilar Highway east of Kilcoy. The Kilcoy Creek Bridge will be demolished and a new concrete, wider bridge will be constructed. 

Detailed design work was finalised in 2017 and the $5.88 million project has been funded and will be delivered as part of the Federal Government’s Heavy Vehicle and Productivity Program. The Queensland Government has contributed 50% towards the construction of the important bridge upgrade. 

The upgrade will provide a 15.25 metre wide concrete bridge with a dedicated pedestrian pathway to improve capacity and safety for pedestrians, cyclists, motorists and heavy vehicles travelling on the D’Aguilar Highway.

Transport operators will benefit from the upgrade as current load constraints for the timber bridge will be removed and any risk of future load limiting. The upgrade will service several key economic activities nation-wide. For example, the Beef and Agriculture industries contribute significantly to the Queensland economy and this important upgrade will provide a vital link route for the freight industry. 

Construction started in early July 2019 and is expected to be complete by mid-2020, weather and construction conditions permitting.

As part of the program of works, traffic will be diverted onto a temporary 2-lane side track which will carry traffic over Kilcoy Creek while the timber bridge is being demolished and replaced.
