Princes Highway at Acacia Road, Oak Road, Kingsway and President Avenue, Kirrawee

The NSW Government is funding this project to ease congestion and improve travel time on Sydney’s busiest corridors.

Updates and announcements

Roads and Maritime Services will continue work on this project. For details of work completed and work coming up, please view the March 2019 project update (PDF, 346Kb).

Pedestrian access detours

Several pedestrian detours are in place within the project site. Until the end of June 2019, there will be a temporary footpath closure along the western side of Princes Highway between Oak and Bath roads. Pedestrians will need to walk down Oak Road, along Monro Avenue and up Bath Road as a detour while this closure is in place. There will be no impact to residential driveway access.


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 of the project

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.

Work to date

Since work started in April 2018 we have:

  • set up the site compound
  • started work to upgrade the central median on Princes Highway
  • moved services and started to relocate utilities on Princes Highway and President Avenue
  • completed President Avenue work with new medians, upgraded turning lanes, new lights and right turn peak hours ban to improve traffic flow.

What's happening next?

  • Construction of a southbound slip lane at Kingsway, and opening of third right turn bay onto Kingsway for eastbound traffic.
  • Night work will continue along Princes Highway and Acacia Road.
  • Set up of an additional site compound on the corner of The Boulevarde and Wandella Road, Miranda.
  • Drainage work at Acacia Road south will continue.
  • Traffic light upgrades will continue in stages.
  • Construction of the service road will continue.
  • Construction of the retaining walls on the service road along Princes Highway.

Community engagement

Roads and Maritime invited feedback on the proposal in May and June.2017. A total of 220 submissions were received in response to the display of the Review of Environmental Factors (REF). This included one submission from the Sutherland Shire Council, and 219 submissions from the community. Of the total submissions, 19 were in support of the proposal, two opposed the proposal, 142 did not state a preference on the proposal, and 56 were not relevant to this proposal (ie concerned other proposals of the Gateway to the South Pinch Point Program, or more general road network improvements).
