Great Western Highway Upgrade Program

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

The first stage of consultation has now closed on the strategic corridor between Katoomba to Mount Victoria and for the corridor reserved in 2013 between Mount Victoria and Lithgow. All feedback received will continue to shape the project ahead of the next stage of consultation planned for mid 2020.

Once the highway has been upgraded between Katoomba and Lithgow, road users will save up to 10 minutes in travel time and over 95km would be two lanes each way between Emu Plains and Wallerawang.

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, $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.
