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

  • Constructing a bridge over Ocean Reef Road
  • Commencing in March 2019, construction 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.

TheOpen Concept design PDF for the interchange provides more details.

Project update

Temporary alignment now in place

​​A temporary roundabout has been opened to the east of Wanneroo Road to move traffic away from the existing intersection during the construction of the new interchange. The temporary alignment will maintain traffic flows in all directions during the construction works. Traffic management and signals are in place during peak hours to help users adjust to the changed conditions and allow traffic patterns to become established.
Read the December 2019 Project Update​ for more information.

The second stage to the temporary alignment will be in place from 10 December, with road users on new lanes to the south of the existing traffic lanes on Ocean Reef Road west of Wanneroo Road.

Relocation of Western Power Infrastructure

Western Power will be removing street lights and relocating portions of the existing distribution and transmission network close to both Wanneroo Road and Ocean Reef Road from October through to early next year.

Both daytime works and after hours works will be required. Open Roadworks Update document​ for more information. 

Construction underway

A new access road for the historic Cockman House has been created from Woodvale Drive. It is fully bitumised and has additional parking and bus bays for visitors. A shared path also runs adjacent to the access road, linking through from Ocean Reef Road to Woodvale Drive.

The const​ruction of noise walls si well underway, with completion anticipated by the end of 2019. See the​Open Noise Wall Fact Sheet PDF for more information.

The right turn movement out of Villanova Street to head south on Wanneroo Road has now been closed, and replaced with a u-turn facility. Sixty per cent of all accidents occurring at this intersection over the past five years have resulted from vehicles turning right out of Villanova Street, with the majority occurring in morning and afternoon peak times. The u-turn provides a safer movement for vehicles exiting Villanova Street to head south on Wanneroo Road. It includes a 70 metre slip lane that can accommodate approximately 11 vehicles, and has been designed for vehicles of up to 8.8m in length, including hearses.

Community engagement

A Community Construction 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

Open the sixth meeting's notes PDF was held in November 2019.

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.

Open June 2019 Project Update

​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.
