  • Upgrade Wanneroo Road and Ocean Reef Road interchange.
  • Construction commenced in March and is due for completion in mid-2020.

Project update

Construction underway

Work has commenced on the Wanneroo Road and Ocean Reef Road Interchange, with traffic management in place from 8 April 2019.

Early works including; surveying, service location, clearing, removal of kerbs and roadside furniture, and the establishment of signage relating to traffic management. The work also includes the construction of a temporary alignment that will move traffic away from the intersection during construction.

While two lanes will be maintained in all directions for the majority of the project, speed reductions will be in place to ensure the safety of both road users and workers on site. If there are occasions when it is necessary to restrict traffic to a single lane in order to safely undertake site works, this will be done outside of peak hours.

Close coordination with the Wanneroo Road and Joondalup Drive Interchange project will be undertaken to reduce the likelihood of works with the potential to significantly disrupt traffic occurring simultaneously on both projects.

Community engagement

As part of the project, noise walls will be constructed in various locations to reduce traffic noise for local residents. Consultation is currently underway with local residents. See the Noise Wall Fact Sheet for more information.

There has been some interest in the community about the different design options considered when upgrading the intersection. An interchange Type Selection Fact Sheet has been developed to explain how the chosen option was decided.

A Community Reference Group has been formed to:

  • assist in identifying, discussing and providing advice on the community issues associated with the project
  • exchange information between us, the contractor and the community
  • provide representative community and stakeholder input into the construction phase of the project

The fourth meeting was held in April 2019.
