Great Western Highway Upgrade Program
Project at a glance
Senior Consultant | Sydney and Sydney Surrounds
Together, the Australian Government and the NSW Government are investing more than $4.5 billion towards upgrading the Great Western Highway between Katoomba and Lithgow.
Transport for NSW is planning and delivering the Great Western Highway Upgrade Program (GWHUP). This is an infrastructure program of national importance. It will make the Blue Mountains and the Central West and Orana more attractive places to live, and will unlock the potential of regional NSW.
The NSW Government has progressively upgraded sections of the Great Western Highway to make it safer and more reliable for all road users. This upgrade will complete the final 34 km connection of a modern dual-carriageway link across the Blue Mountains.
The Great Western Highway Upgrade Program consists of:
Katoomba to Blackheath (East section): Upgrade, duplication and widening of the existing surface road corridor, with connections to a tunnel portal at Blackheath. Through Medlow Bath, the upgrade also includes intersection improvements and a new pedestrian bridge. Click here to view the flythrough video of the East section.
Blackheath to Little Hartley (Central section): Construction of a tunnel bypass of Blackheath and Mount Victoria, with connectivity between the two proposed tunnels currently under further investigation. The Environmental Impact Statement exhibition is planned for late 2022.
Little Hartley to Lithgow Upgrade (West section): Upgrade, duplication and widening of the existing surface road corridor, with connections to a tunnel portal at Little Hartley. This includes a 2.4 km Coxs River Road subsection. Click here to view the flythrough video of the West section.
In addition, there will be packages of work including the subsections through Medlow Bath and Coxs River Road, along with early work enabling packages.
The Program will be delivered in stages over the next decade, with different sections coming to market sequentially.
