Project information


Heathcote Road serves Sydney’s southern and southwestern suburbs, as well as Wollongong, the Illawarra and South Coast.

Around 20,000 vehicles pass through the Heathcote Road and Princes Highway intersection every day, while 3000 road users pass through the Heathcote Road and New Illawarra Road intersection every hour during daily peak periods

Currently, a large number of vehicles queue to turn right out of Heathcote Road onto the Princes Highway, causing congestion and delays at the intersection.

Road users also experience delays and queuing at the intersection of New Illawarra Road and Heathcote Road. This is caused by congestion in the right turn lane in the morning peak period and in the left turn lane in the afternoon peak period.

Project features

The improvements at Princes Highway and Heathcote Road, Engadine include:

  • widening Heathcote Road to add an additional right turn lane onto Princes Highway
  • maintaining the existing left turn slip lane from Heathcote Road onto Princes Highway.

The improvements at Heathcote Road and New Illawarra Road, Lucas Heights include:

  • widening New Illawarra Road to add additional left and right turn lanes onto Heathcote Road
  • installing traffic signals for roads users turning left from New Illawarra Road on to Heathcote Road.


The project will:

  • improve the efficiency and traffic flow at the intersections
  • improve road safety and help reduce the number of crashes
  • ease congestion and improve travel time reliability.
