The upgraded Byron Road will function as an access road to the future Leppington Town Centre Precinct. Amid increased traffic volumes and population density, it will serve as an important link between the Leppington Precincts, to Camden Valley Way and to other Growth LGA (e.g. Liverpool and Campbelltown).

The upgrade works consist of:

• Upgrade of Byron Road between Ingleburn Road and Heath Road from a rural standard to an urban standard two-lane road;
• On-road parking lane on both sides;
• Upgrade of the existing Heath Road and Byron Road T-intersection to a three-leg roundabout; 
• Pedestrian and cycle path network;
• Streetscaping; 
• Stormwater drainage upgrade;
• Utilities relocation and adjustment; and 
• Review of Enivronmental factors.

The project will also deliver works associated with the upgrade of Heath Road and Scalabrini Creek East (Drainage and Open Space) project. These works consist of:

• Upgrade of 200 metres of Heath Road pavement, kerb and gutter and drainage line;
• Installation of box culverts associated with the Scalabrini East project; and 
• Installation of an electrical substation and electrical works for Leppington Oval.
