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 October 2018 project update (PDF, 36.5Mb).

Acacia Road north closure at Princes Highway, Kirrawee from 26 November

The upgrade work requires the closure of the left turn access to Acacia Road north of Princes Highway from Monday 26 November for about nine months, weather permitting. Access will be available for residents from Auburn Street and Clio Street. Pedestrian access will be maintained at all times, although temporary detours may be in place.

We will also be working during extended day time hours on the service road between Acacia Road and Bath Road to complete service relocations.

Our day work hours will be between 7am and 6pm from Monday to Friday and 8am to 1pm Saturdays. Our night work hours will be between 8pm and 5am from Sunday to Friday. We will not be working on public holidays.

Works will be winding down in late December for the Christmas shutdown from 24 December 2018 until the 4 January 2019.


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:

  • moved services to accommodate the water main
  • set up the site compound
  • started work to upgrade the central median on Princes Highway
  • started to relocate utilities on Princes Highway and President Avenue
  • moved the median strip and relocated the traffic lights at President Avenue
  • closed access to Kenneth Avenue to and from Princes Highway.

What's happening next?

  • night works will continue along Princes Highway and President Avenue
  • the drainage works at Acacia Road south at President Avenue intersection are due to be completed in early December
  • the current works on Princes Highway median will continue in preparation for traffic changes in late October/early November
  • right turns from Princes Highway into Oak Road in both directions will be permanently closed. Signs will be installed for road users indicating the closure date
  • from October 2018 to January 2019 the Princes Highway and President Avenue intersection will open in stages.

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).
