Bruce Highway (Maryborough – Gin Gin), Saltwater Creek and Deadmans Gully, flood immunity upgrades

Construction is underway to improve flood immunity along an 11km section of the Bruce Highway between Maryborough and Torbanlea.

This Bruce Highway Upgrade Program funded project will improve the safety and reliability of the Bruce Highway and reduce the social and economic impacts associated with flood-related highway closures.

West of the existing highway, 2 new high-level bridges will be constructed on a new alignment, to replace the existing Saltwater Creek and Deadmans Gully crossings. 

Between Maryborough and Torbanlea, 4 floodways north of Saltwater Creek, will be upgraded, with the floodways and bridges constructed to provide a flood immunity for a one-in-100-year flood event. 

The project will minimise disruption through flood related closures and improve safety along this section of the Bruce Highway for all road users.
