The final leg of road construction for Collier Rd with the NorthlinkWA project will be happening this weekend! This will involve building of two roundabouts on Collier Road and opening up the on and off-ramps from the Tonkin Highway.
On completion, Tonkin Highway will transform to a freeway with six lanes and traffic will become free-flowing with the removal of traffic lights at Collier Road, Morley Drive and Benara Road.
Construction of the roundabouts will require a closure of Collier Road as follows: 7pm Friday 12 January to 5am Wednesday 17 January.
The roundabouts will have only one lane in each direction. They will be temporary. You can see here for the animation of what the final layout will look like.
Diversions will be in place and can be viewed here
