Project information

The official name of the bridge is Bridge 152, however it is often referred to as 'the narrow bridge over Woronora River'.

For the community this bridge symbolically represents a time, some 75 years ago, when the bridge was all that connected the south to the west.

Built by the military the narrow Heathcote Road Bridge over Woronora River history dates back to 1943. The bridge sits over the Woronora River nestled amongst the spectacular Heathcote and Royal National Park.

Transport for NSW is making improvements to the bridge as it is limited in width, and has a history of community concern for motorist safety when crossing the bridge.

  • The narrow bridge on Heathcote Road over the Woronora River is over 75 years old, and its being improved to make it safer to travel.
  • We've listened to the community and their concerns that the bridge is in need of safety improvements. Narrow road lanes and shoulders of the bridge do not provide for the free and continuous flow of road traffic.
  • Investigations have identified improvements to lane and shoulder widths, including on the approaches that will bring the bridge in line with today's safety standards.
  • The plan is to carry out the works uninterrupted over six months to complete the improvements swiftly and reduce how long the community is affected by the bridge and road closures.

The key benefits to the community include:

  • improved road safety across the bridge
  • reducing the risk of potential road accidents due to wider lane widths
  • improved travel time on Heathcote Road between New Illawarra Road, Lucas Heights and the Princes Highway, Engadine
  • support growth in Sydney's population by improving transport connectivity and better access to employment opportunities for the community
  • bridge improvements will preserve an important part of the local community's history

Thank you for your feedback, the REF submissions report is now available on the Heathcote Road bridge virtual information centre.

Once the decision to proceed has been made, final design will be completed. Transport for NSW will be able to advise the community about the full construction schedule.

We will continue to keep the community updated as the project progresses.
