Indicative only, final layout to be determined through detailed design

The Medlow Bath Upgrade has now been approved, with the Medlow Bath section to be the first section of the highway to be upgraded. The project will managed by Transport and funded by the Australian and NSW Governments.

In December 2022, Transport for NSW (Transport) announced Abergeldie Complex Infrastructure had been awarded the contract to begin major roadwork at Medlow Bath in early 2023. This marks the first section of major work on the Great Western Highway upgrade between Lithgow and Katoomba.

We will continue to update the community as the project progresses.
