Dawson Highway (Gladstone - Biloela), various locations, strengthen bridges and widen and rehabilitate pavement

The department has widened 3km of road, and completed headstock strengthening works at Collards Creek and Callide Creek bridge between Calliope and Biloela, to improve the efficiency of the Dawson Highway. Detailed design has been completed for strengthening works at Callide Creek bridge.

The former $40 million Dawson Highway Timber Bridge Project, fully-funded by the Queensland Government, was completed under budget and ahead of schedule in early 2018. It delivered regional freight efficiency improvements and flood immunity on the Dawson Highway.

The $14.2 million savings from that project was reinvested into the Queensland Transport and Roads Investment Program 2019-20 to 2022-23.

The next stage of work is part of the continuing improvement of the Dawson Highway to support regional growth and enable economic development.
