Great Western Highway looking towards Hartley Valley

Great Western Highway Upgrade Program - Katoomba to Lithgow

The NSW Government is investing $2.5 billion towards upgrading the Great Western Highway between Katoomba and Lithgow. The program will provide safer, more efficient, more reliable journeys, and better connect communities with the Central West.

The first stage of consultation has now closed. We will be refining options and will be consulting again with the community in mid 2020.

The NSW Government has progressively upgraded sections of the highway to make it safer and reliable with the most recent project at Kelso opened to traffic in March 2017. In 2018, $30 million was announced to upgrade the highway between Kelso and Raglan.

There have already been important safety improvements delivered through the safety upgrade program along the Great Western Highway at Blackheath, Mount Victoria and Forty Bends. This work has seen improved road surfaces, intersection upgrades, and lane widening delivered as part of the $250 million investment by the Australian and NSW governments.

Project information

Nominations now closed

Transport for NSW is establishing the Blackheath Co-Design Committee to discuss and refine route options for upgrading the Great Western Highway through Blackheath. Options will then be made available for broader community consultation.

The Committee will be made up of Great Western Highway Upgrade Program team members, key local stakeholders, community representatives and Blue Mountains City Council representatives. Nominations for the Committee have now closed.

Transport for NSW supports the Government’s response to COVID-19. To ensure the safety of our staff and customers, we will be postponing the Blackheath Co-Design Committee meetings at this time.
