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, of many rounds of consultation, closed in December 2019. We want to thank the community for providing valuable feedback. We have now published the Community Consultation Summary Report which responds to the 1759 submissions received from community members in and beyond the Blue Mountains. View or download the Community Consultation Summary Report.

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

In November and December 2019 Transport for NSW held the first round of community consultation on the proposed upgrade from Katoomba to Lithgow. The Community Consultation Summary Report (PDF, 18.4Mb), summarises what you have told us so far, and allows us to provide information on key areas that you are interested in, like the environment and road use, safety, village impacts, and freight.

Meetings underway

Transport for NSW has established 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 is made up of Great Western Highway Upgrade Program team members, key local stakeholders, community representatives and Blue Mountains City Council representatives.

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