Following the works, there will be two lanes of traffic in each direction on Collier Road, traffic lights on the bridge and pedestrian paths opening between Embleton Avenue and Beechboro Road South and Grey and Jackson streets.
Works to complete landscaping will continue around the interchange which will involve lane closures, speed reductions and traffic management.

Access to businesses in this section will be available with traffic management in place.
Tonkin Highway will remain open but there will be no access to Collier Road.
There will be no restricted vehicle access to surrounding industrial area.
