Princes Highway and Port Hacking Road, Sylvania


Project overview

The upgrade of the Princes Highway and Port Hacking Road intersection at Sylvania was completed in early 2019.

Project information


The intersection of Princes Highway and Port Hacking Road, Sylvania was identified for improvement as part of the NSW Government’s $300 million Gateway to the South Pinch Point Program. Princes Highway is one of three routes that cross the Georges River to link Sydney’s CBD with Sutherland Shire and the inner southern and inner western suburbs of Sydney. Princes Highway is also the principal road link between Sydney and the Illawarra and south coast regions.

The intersection caters for around 6,500 vehicles during the AM and PM peak periods. The major movements are vehicles traveling through the intersection along Princes Highway and the right turn from Port Hacking Road onto Princes Highway.


The upgrade widened Princes Highway to allow more vehicle movements through the intersection. It also delivered a signalised pedestrian crossing over Madeira Street and a new, dedicated bus bay to ease eastbound congestion on Princes Highway.
