Katoomba to Blackheath - Great Western Highway Upgrade Program

Reviewed

Together, the Australian and NSW Governments have committed more than $2.5 billion towards the East and West sections of the Great Western Highway Upgrade, between Katoomba and Blackheath, and between Little Hartley and Lithgow, respectively.

The Katoomba to Lithgow duplication will provide major economic and safety benefits. It will improve the connection between Central West NSW and Sydney, reduce congestion, improve resilience and freight productivity, and provide a safer and more reliable journey for thousands of residents, commuters, tourists and freight operators who travel in, around and through the Blue Mountains.

Transport for NSW is proposing to widen the Great Western Highway between Katoomba and Blackheath to two lanes in each direction.

The upgrade is split into two sections:

  • Katoomba to Medlow Bath between Rowan Lane, Katoomba and Bellevue Crescent, Medlow Bath (about 3.5 kilometres)
  • Medlow Bath to Blackheath between Station Street, Medlow Bath and Evans Lookout Road, Blackheath (Approximately 2.3km).

Both the Katoomba to Blackheath (East section) and Medlow Bath upgrades have 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.

The Submissions Reports and Community Consultation Reports for both sections are now available on the project website portals at nswroads.work/gwheast and nswroads.work/gwhmedlow

Project information

Background

In March 2019, the NSW Government committed $2.5 billion towards the upgrade of the road corridor between Katoomba and Lithgow and Transport began consultation on strategic options for this upgrade.

In the 2021 Federal budget, the Australian Government committed $2.03 billion towards the delivery of the eastern and western sections of the upgrade, including the section between Katoomba and Blackheath.

Transport investigated a wide range of upgrade options between Katoomba and Lithgow, to make sure we deliver a connection that minimises environmental impacts, supports local economies, improves travel times and safety and is financially responsible.

A range of options connecting these towns were progressively evaluated against viability criteria.

The result of the options selection process was to progress a surface upgrade of the highway between Katoomba and Lithgow, including duplication of the existing roadway, improved intersections and facilities and an upgraded active transport link through the mountains.

Traffic modelling indicates that approximately 40 per cent of traffic on the Highway between Katoomba and Little Hartley is traveling between Katoomba, Medlow Bath, Blackheath, Mount Victoria and/or the Darling Causeway.

Benefits

  • Improve road alignment
  • Water quality
  • Recognising historical significance
