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

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

Background

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.

Project

The project includes:

  • permanently banning the right turn movements from Princes Highway into Oak Road (in addition to the current peak period ban)
  • widening Princes Highway on northern side to accommodate additional lanes along the road corridor
  • an additional northbound right turn lane from Princes Highway into Acacia Road
  • an additional northbound through lane on Princes Highway at Auburn Street
  • an additional southbound through lane on Princes Highway at Acacia Road
  • an additional northbound and southbound through lane on Princes Highway at Oak Road
  • an additional northbound right turn lane from Princes Highway into Kingsway
  • extension of left turn filter lane from Princes Highway southbound into Kingsway
  • new pedestrian crossing facilities at Oak Road intersection
  • enhancing local service road parallel to Princes Highway between Acacia Road and Oak Road
  • closing access to Kenneth Avenue to and from Princes Highway
  • removing about 115 trees along the corridor
  • widening on the south-eastern side of the intersection and into the existing median on the eastern side of the intersection, to accommodate lengthened right and left turn lanes from President Avenue, onto Princes Highway. This would result in the removal of about six trees
  • widening into the existing median on the southern side of the intersection to accommodate a lengthened right turn lane eastbound onto President Avenue
  • widening into the existing median on the western side of the intersection to accommodate a dedicated left turn lane from President Avenue onto Princes Highway
  • introducing a peak hour right turn ban from President Avenue into Princes Highway northbound between 3pm and 7pm, Monday to Friday
  • modifying the median on the northern side of the intersection to improve safety for vehicles turning right from President Avenue northbound onto Princes Highway
  • relocating the traffic control signals in the existing median on the western side of President Avenue
  • installing new pavement, kerbs, drainage and signage
  • relocating other utilities
  • installing two new 750mm water mains under the service road
  • asphalting and line markings.

Benefits of the project

Benefits would 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.

Community engagement

Roads and Maritime is continuing to work with the Sutherland Shire Council regarding local traffic and access matters, including a landscaping plan.

We sought feedback on the Review of Environmental Factors (REF) for the proposed intersection improvements along Princes Highway at Acacia Road, Oak Road and Kingsway Kirrawee in May, June and July.

Community information sessions were held in three locations in the local area during consultation, providing one-on-one time with the project team.

An online tool was also available for the community to provide feedback on the projects via an interactive map.
