Princes Highway and Port Hacking Road, Sylvania

The NSW Government is funding this proposal as part of its $300 million Gateway to the South Pinch Points Program which aims to ease congestion and improve journey reliability on Sydney’s key southern corridors.

Updates and announcements

Roads and Maritime sought feedback from the community and stakeholders on intersection improvements at the Princes Highway and Port Hacking Road between May and June. A community consultation (PDF, 1.19Mb) report summarising the comments and responses was released in August 2017, including community notification (PDF, 453Kb) that was distributed to residents.


The intersection of Princes Highway and Port Hacking Road, Sylvania has been identified as part of the NSW Government’s $300 million Gateway to the South Pinch Point Program. This program aims to address critical pinch points along the A1, A3 and A6 routes south of the M5 Motorway, including The Princes Highway. It focuses on short to medium term solutions to improve travel time and reliability for all road traffic including buses and freight.

Princes Highway is the principal route linking southern coastal towns of NSW with Sydney. In a regional context, Princes Highway is one of three routes that cross the Georges River to link Sutherland Shire with the Sydney CBD as well as the inner southern and inner western suburbs of Sydney.

Currently, the Princes Highway and Port Hacking Road intersection is heavily trafficked, catering for approximately 6,500 vehicles during the AM and PM peak hours. The major movements are the vehicles traveling through the intersection along Princes Highway, and the right turn from Port Hacking Road onto Princes Highway (eastbound).


This proposal includes:

  • Widening the westbound side of Princes Highway to increase the length of the three through lanes from 42 metres to 123 metres
  • Relocating the bus shelter with a new indented bus bay on Princes Highway eastbound
  • Upgrading traffic signals and signs
  • Asphalting and painting line markings
  • Relocating lighting and power poles
  • Adjusting existing utilities.

Community engagement

Roads and Maritime invited feedback on the proposal in May and June. We received feedback from 43 people, with 18 supporting the proposal, 24 not stating a preference and one person who opposed the proposal

Next steps

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