The Australian and NSW governments are upgrading Bringelly Road as part of the Western Sydney Infrastructure Plan, a 10 year, $3.6 billion road investment program.
The Bringelly Road Upgrade will deliver new and upgraded roads to support integrated transport in the region and capitalise on the economic benefits from developing a western Sydney airport at Badgerys Creek. It will also improve safety, increase road capacity and reduce congestion and travel times in the future.

This 10km project will include the upgrade of Bringelly Road from two lanes to a six lane divided road between the eastern side of Upper Canal bridge and the western side of the Eastwood Road intersection, through the future Leppington Town Centre. The rest of Bringelly Road will also be upgraded from two lanes to a four lane divided road with a central median, which would allow for widening to six lanes, when required
