“Bringelly Road Upgrade Stage 2 is part of a broader $3.6 billion program of road works which aims to support major growth areas planned for Western Sydney, including the Western Sydney Airport,” said Infrastructure Australia Chief Executive Philip Davies.

“With the first stage of the Bringelly Road upgrade already under construction, Stage 2 involves widening the remaining 4.3km of two-lane rural road between King Street and The Northern Road to a four-lane divided carriageway with a wide central median.

“Development initiatives such as the Western Sydney Priority Growth Area and South West Priority Land Release Areas, together with the Western Sydney Airport, will drive significant population and employment growth in the region.

“Over the next 30 years the south-west region's population will increase by 300,000 people, with some 57,000 new jobs expected to be created.

“This will lead to a marked increase in traffic volumes on major access routes in the region, with average daily traffic on Bringelly Road expected to increase from under 6,000 vehicles per day currently to around 24,000 vehicles per day, which is growth of over 300%.

“Along with a wider program of works that includes upgrades to The Northern Road and development of the M12 connecting The Northern Road with the M7, this project will ensure the region's road network can adequately meet this increase in traffic demand, and support economic growth in Western Sydney. It will also deliver improved safety outcomes for road users.

“The next task will be to increase investment in public transport to realise this economic growth and provide greater access between the south-west and major commercial centres such as Liverpool and Campbelltown,” Mr Davies said.

The Infrastructure Priority List identifies nationally significant projects and initiatives in every state and territory, and is regularly updated as the Infrastructure Australia Board receives and assesses new business cases from project proponents.
