Project background

Wyong Road is the major road linking the M1 Pacific Motorway with Wyong, Tuggerah, The Entrance and the surrounding coastal suburbs. The roundabouts at Mingara Drive and Tumbi Road are heavily congested during peak hours.

The upgrade will replace the existing roundabouts with traffic lights to improve traffic flow and safety for the 48,000 vehicles using this section of Wyong Road each day.


Key benefits of the upgrade include:

  • Improved traffic flow on Wyong Road
  • Improved safety for all road users
  • Improved pedestrian and cycle network.
