  • improving traffic flow for better and more reliable trips
  • making it easier to move freight
  • allowing for predicted increases in traffic
  • providing safer access to and from the motorway.


Work will take place between the Kariong and Somersby interchanges, Tuggerah and Doyalson interchanges and at the Weakleys Drive and John Renshaw Drive intersection. Key features include:
