This project involved the construction of a bridge over Ocean Reef Road, including signalised off and on ramps, service relocations, drainage improvements and realignment of paths and pedestrian crossing points.

A new U-turn facility was installed on Wanneroo Road (north of Villanova Street) to assist southbound traffic movements and a new access road for Cockman House off Woodvale Drive has also been constructed.

Congestion relief has been noticeable already, with 75,000 daily commuters saving approximately 7 minutes in travel time through this busy intersection.


  • Improved connectivity and travel times for local businesses and the community
  • Allow traffic to flow more freely by raising Wanneroo Road over Ocean Reef Road
  • Improved road safety
  • Safer road access to nearby suburbs
