​​​​​​​​Wanneroo Road and Ocean Reef Road Interchange

  • Constructing a bridge over Ocean Reef Road
  • Construction commenced in March and is due for completion in mid-2020.
  • Improve safety at one of Perth’s most congested intersections

Overview

Work will include construction of a bridge over Ocean Reef Road including signalised off and on ramps, service relocations and drainage improvements and realignment of paths and pedestrian crossing points.

Theconcept design for the interchange provide more details.

Project update

Construction underway

Construction is now underway, with the first stage of works involving:

  • Demolition of the former BP service station site and other redundant buildings
  • Site clearing of shoulders, median strips and other construction areas as required
  • Site investigations to identify the location of services and commencement of service relocations
  • The construction of a new access road to Cockman House
  • Temporary diversion of the shared path adjacent to Cockman House
  • Establishment of traffic management and site facilities

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 theNoise 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

Thefifth meeting was held in late- June 2019.

 FAQs

​Plans have been in place for more than 20 years. Projects of this nature are funded based on priorities related to congestion, safety and value for money. 

Interchange type selection

During construction, access on Wanneroo Road and Ocean Reef Road will be maintained, with the assistance of traffic management. The majority of the works will be undertaken from 7am to 7pm, Monday to Saturday. Out of hours works may be required to complete parts of the job due to safety, traffic volumes or space requirements.

Road users, nearby residents and local businesses will receive advanced notification for upcoming traffic disruptions.

A temporary road will be constructed to the south of Ocean Reef Road and east of Wanneroo Road, to maintain traffic flows during construction of the new Wanneroo Road bridge. It is anticipated that traffic will be moved onto this temporary road in early spring 2019.

Update - June 2019

​Noise walls will be built in various locations to reduce traffic noise for local residents.  

The location of noise walls is determined by noise monitoring to assess current noise levels, and noise modelling which calculates noise levels in 2041.

We are working closely with property owners to coordinate the construction of noise walls.

Find out more information in our fact sheet. 

​We're working closely with our Construction Reference Group to ensure the landscaping and urban design treatments compliment the local surroundings.

While some vegetation will be removed, it will be limited to locations where road and bridge works make it impossible to retain existing vegetation.

Landscaping and revegetation works will be undertaken during the winter of 2020.

​During construction, equipment and vehicle movements may create some noise, vegetation and dust. To minimise disturbance as much as possible, ongoing monitoring and testing will be undertaken and where necessary, proactive controls will be implemented including modification of construction activities.
