Wanneroo Road and Ocean Reef Road Interchange
- Constructing a bridge over Ocean Reef Road.
- Commencing in March 2019, construction is due for completion in late-2020.
- Improve safety at one of Perth’s most congested intersections.
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. View the map to find out more about the interchange.
Bridge beam installation
The project reached a major milestone on Thursday 4 March, with the installation of 12 bridge beams being completed within just 15 hours. Work commenced on the installation of the 12 beams, which range in length from 18.1 m to 21.8 m, on Wednesday 3 March. All beams were in place by close of business Thursday 4 March. The rate of installation - averaging just over an hour per beam - was achieved by locating the crane and beams in a position that minimised the need to relocate the crane multiple times. The next step is to prepare the steel reinforcements to support the 200mm concrete slab that will be laid on top of the beams.
Traffic control before and after school hours
Traffic controllers will be on site from 7.15am to 8.45am, and from 3pm to 4pm, Monday to Friday during school term to ensure students can safely cross Ocean Reef Road west of Wanneroo Road during the construction of the project.
Open Roadworks Update document for more information.
A temporary roundabout was installed to move traffic away from the existing intersection and maintain movements in all directions during construction of the new interchange.
Traffic management and signals remain in place during peak hours.
The temporary roundabout operates under the same road rules as all roundabouts in WA. It has been independently audited three times and confirmed to be compliant with all road safety regulations. View the Temporary Roundabout Fact Sheet for more information from the Road Safety Commission.

How will traffic be managed during construction?
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
How will noise levels be managed?
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.
How will impacts on visual amenity be managed?
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.
Will construction affect my home?
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.
