West Central East

Overview

Together the Australian and NSW Governments are investing more than $4.5 billion towards upgrading the Great Western Highway between Katoomba and Lithgow. The Great Western Highway Upgrade will reduce congestion, deliver safer, more efficient and reliable journeys for those travelling in, around and through the Blue Mountains, and better connect communities in the Central West.

The Great Western Highway Upgrade Program (the Program), once completed, will reduce congestion and provide safer, more efficient and reliable journeys for everyone travelling in, around and through the Blue Mountains, and better connect communities in the Central West.

The NSW Government has progressively upgraded sections of the Great Western Highway to make it safer and more reliable for all road users.
