Road Resilience Program


Project overview

The NSW Government is delivering the Resilient Valley, Resilient Communities - Hawkesbury-Nepean Valley Flood Risk Management Strategy (the Flood Strategy).

As part of the Flood Strategy, Transport for NSW has identified more than 100 infrastructure improvements at key low points of the flood evacuation road network in the Hawkesbury-Nepean Valley.

Latest news

Dec 2022 – Investigation work on The Northern Road and Londonderry Road

Transport for NSW will carry out investigations from Monday 12 December to Friday 28 April 2023. Work will include ground survey, geotechnical investigations involving drilling boreholes, test pits and core drilling to test soil and road conditions.

Aug 2022 – Concept design and current planning stage

Transport for NSW is working closely with local councils on the planning of the improvements across state, local and regional roads.

Planning work will commence from August, including site investigations to inform the development of identified improvements.

Preliminary site investigation works will be undertaken across the four Local Government Areas of Penrith, Hawkesbury, Blacktown and The Hills.

Site investigation work

Investigations will include survey, utility, environmental and geotechnical investigations.

Transport will soon be in contact with property owners where we require access to private property to carry out the investigations.

Project information

Road Resilience Program

The NSW and Australian Governments will commit $33 million towards planning for more than 100 infrastructure improvements that will help people evacuate safely ahead of a flood in the Hawkesbury-Nepean Valley.

The improvements will make the flood evacuation network more resilient, particularly at road low points in key locations within the valley.

Transport for NSW has identified road infrastructure improvements across four Western Sydney Local Government areas: Penrith, Hawkesbury, Blacktown and The Hills.

The improvement projects include road shoulder widening, new culvert and bridge structures, road raising, pinch point upgrades and drainage improvements.

These projects will improve the resilience of the road network so that residents can evacuate from the area safely in the event of a flood.

Transport will work closely with local councils to deliver the improvements across state, local and regional roads.

Hawkesbury-Nepean Flood Risk Management Strategy

The Hawkesbury-Nepean Valley has the highest flood exposure in NSW due to its unique landscape and large existing population. Floods in the valley can have a significant impact on people’s lives, livelihoods and homes.

The NSW Government is delivering the Resilient Valley, Resilient Communities – Hawkesbury-Nepean Flood Risk Management Strategy (the Flood Strategy) to reduce and manage the risk of flooding in the region – now and into the future.

Transport for NSW has an important role in leading road and transport outcomes in the Flood Strategy. Due to the potential depth, extent and duration of floods in the valley, mass evacuation during flooding is critical to reduce the risk to life.

The Flood Strategy outcomes being led by Transport include:

  • coordinating the development of a regional evacuation model that identifies the flood evacuation capacity requirements for different areas in the valley
  • developing Regional Evacuation Road Guidelines that identifies the flood evacuation road network design requirements for the valley
  • design and rollout of flood evacuation road signage across the valley (completed)
  • planning for targeted flood evacuation road infrastructure improvements for local and regional flooding to enhance access to and resilience of the existing flood evacuation routes (Road Resilience Program).

Next steps

We will continue to keep the community updated as we progress the investigation work that will determine our Concept Design.
