Toowoomba–Cecil Plains Road, improve safety

Toowoomba-Cecil Plains Road is a critical transport route for the Darling Downs region, connecting agricultural communities to markets and essential services.

To improve safety and traffic flow, a range of upgrades are being implemented to reduce the risk of crashes and enhance the driving experience of all road users.

In 2024, local residents and community members were consulted to identify concerns and gather ideas for improving the road. Feedback from this consultation has been incorporated into the final project design to ensure it addresses community needs.
