Project information


The Princes Highway is an important urban arterial road, and forms part of the A1 road corridor. The A1 connects the south coast of NSW and Wollongong to Sydney. It also provides access to major roads including the M5 Motorway, A3 King Georges Road, A36 Princes Highway (city) and M1 Pacific Highway.

Road users are currently experiencing congestion due to high volumes of vehicles travelling along the corridor and turning right at the intersections of Acacia Road, Oak Road and Kingsway. In addition, there are currently high volumes of vehicles travelling in both directions on President Avenue and the Princes Highway. These delays are caused by turning vehicles blocking through traffic.

This project aims to ease congestion at these intersections and improve journey reliability for all road users.


Benefits include:

  • improved operation of Princes Highway along the corridor and at the intersections with Acacia Road, Oak Road, Kingsway and President Avenue
  • improved safety at the intersections, with a reduction in the number of rear-end crashes and crashes involving motorists changing lanes
  • reduced traffic delays and a better flow of traffic for motorists at all points along the corridor.

Program of works

Since work started in April 2018 we:

  • upgraded the central median on Princes Highway
  • moved services and relocated utilities on Princes Highway and President Avenue
  • moved the median strip, relocated the traffic lights and extended turning lanes at the intersection of President Avenue and Acacia Road.
  • extended the northbound right-turn slip lane on Acacia Road approaching President Avenue
  • completed a new left-turn slip lane from Princes Highway onto Kingsway
  • constructed a new retaining wall on the northern side of Princes Highway between Acacia and Oak roads, and carried out utility upgrades
  • completed retaining walls on Princes Highway
  • construct a new southbound left-turn lane from Oak Road onto Princes Highway
  • a third eastbound right-turn lane was constructed from Princes Highway into Kingsway
  • continued the drainage system on the Princes Highway.
