The Great Western Highway Upgrade Program is a major investment project which involves the construction of a new four-lane carriageway, and 11km 2-lane dual tunnel, set to reduce traffic congestion and provide safer, more reliable journeys for all through the Blue Mountains.

Covering a distance of approximately 34 kilometres, this upgrade program will cater to the future growth of the region, which is projected to reach a staggering 300,000 by 2036. To achieve this, multiple projects have been put in place, including several surface works projects and the construction of an impressive 11-kilometer twin tunnel between Blackheath and Little Hartley.
