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.

Between Maryborough and Torbanlea, a new high-level bridge at Deadmans Gully has been constructed on a new alignment to replace the existing crossing.

Construction continues to replace the existing Saltwater Creek crossing with a new high-level bridge and upgrade 4 floodways to provide 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.
