MAIN Roads has released a concept plan for the $65 million Wanneroo Road-Ocean Reef Road interchange as contractors prepare to start work on the $50 million Joondalup Drive flyover.
It expects to award a contract for the southern project in late 2018, which will include building a road bridge as well as on and off ramps with traffic signals.
Main Roads developed the concept design after considering options to meet current and future traffic needs, but said the final configuration would be determined during the detailed design stage after it awards the contract.

Plans include installing a U-turn facility on Wanneroo Road, north of Villanova and south of East Road, to help southbound motorists.
Vehicles will still be allowed to turn right from Wanneroo Road into Villanova Street, and left-turns in and out of the junction.
Main Roads also plans to remove access to Cockman House from Ocean Reef Road, creating parking and access via a new road off Woodvale Drive.
A community reference group established for the project includes residents from Regent Waters Estate, Pearsall and Woodvale, as well as representatives from the cities of Wanneroo and Joondalup, and the Main Roads project team.
According to the 2017 Australian Road Research Board Report, the Wanneroo Road-Ocean Reef Road intersection was ranked Perth’s 13th most congested intersection and there were 197 crashes there, including 167 rear-end crashes, between 2013 and 2017.
CPB Contractors is due to start building the interchange at Joondalup Drive in November.
It will install barriers on Wanneroo Road, Joondalup Drive and the northern side of the Burns Beach Road roundabout early next month.
Two bus stops on Joondalup Drive will temporarily close while works take place, with alternative stops operating farther west.
While the roads will remain open with lower speed restrictions, some pedestrian and cycle paths will be temporarily relocated.
Daytime works planned until February will include earthworks, drainage and paving, and will require the use of excavators, loaders, rollers, dump trucks, graders, bob cats, water carts and light vehicles.
Night works, starting this week, will include locating underground services and barrier installation.
The Wanneroo Road-Joondalup Drive interchange project is due for completion in early 2020.
