​Wanneroo Road and Ocean Reef Road Interchange

The Wanneroo Road and Ocean Reef Road Interchange project is funded by the Commonwealth and State Governments as part of a $2.3 billion investment in road and rail infrastructure, announced by Premier Mark McGowan on 7 May 2017.

Both Wanneroo Road and Ocean Reef Road carry high traffic volumes, and the intersection ranks as one of the most congested in Perth. This project will boost capacity and traffic flow, ease congestion and improve safety for all road users.
