South Region road maintenance and infrastructure projects
Project overview
Our boundaries stretch from the bustling metropolitan city of Wollongong to the rich agricultural lands of the Riverina, and down to the far south coast and the Snowy Mountains.

About our region
Our region’s landscape - ranging from Australia’s highest peaks to rural and bush covered plains, hinterland areas and dramatic coastlines – is as diverse as we are.
It is a place where communities, transport networks and economic connections interact outside NSW, to both Victoria and the ACT, and to neighbouring regions. Businesses utilise direct freight access to Port Kembla, Port Botany and Port of Melbourne, as well as the many airports across the region.
Through strategic planning projects and delivering new and upgraded infrastructure, we improve road safety while enhancing tourism, driving economic growth and creating vibrant regional spaces.
What we do
Maintenance and safety improvements
We manage and maintain the state roads and bridges across southern NSW. Maintenance is a critical part of ensuring the road network runs smoothly and ensuring safe and reliable journeys for all road users. We also deliver safety treatment upgrades, such as rumble strips and widened centre lines, to improve safety for all road users.
Activities include:
- repairing and resurfacing roads
- maintaining bridges, culverts and slopes
- maintaining signage, vegetation and safety barriers
- clearing gutters and drains, and litter collection
- maintaining traffic signalling systems
- installing new safety treatments
- other routine works.
Major projects
We are delivering multiple large infrastructure projects to improve safety and connectivity, ease congestion, and improve journey times and reliability for our local communities, freight operators, commuters and visitors.
Some of our key major infrastructure projects include:
- Barton Highway upgrade
- Historic Nowra Bridge repurposing
- Marshalls Creek Bridge replacement
- Mount Ousley interchange
- Swan Hill Bridge replacement
Some of our recently completed projects include:
Planning
As well as maintaining roads and bridges across the state road network, we also plan for future improvements and upgrades to the network. This ranges from broad regional transport plans to more localised plans or studies for individual towns or transport modes. It also includes planning for future projects such as major infrastructure, safety improvement work or intersection upgrades.
Some of our current planning projects include:
- Picton Road upgrade
- Bulli bypass
- Milton and Ulladulla bypass
- Wagga Wagga Northern Access Strategy
- South East and Tablelands Strategic Regional Integrated Transport Plan
- Illawarra Shoalhaven Strategic Regional Integrated Transport Plan
- Riverina Murray Strategic Regional Integrated Transport Plan
Natural disaster recovery
Floods, bushfires and other natural disasters have caused significant damage across NSW state roads in recent years. We are working to repair natural disaster damage on several key roads across the Illawarra and South Coast, including Lawrence Hargrave Drive, Moss Vale Road and Snowy Mountains Highway.
