What's happening
Mitchell Freeway northbound off-ramp and southbound on-ramp lane closures
As works progress on the future Stephenson Avenue grade-separated interchange there will be changed traffic conditions when you access and exit Mitchell Freeway from Stephenson Avenue and Cedric Street.
The Mitchell Freeway northbound off-ramp access to Cedric Street eastbound has been reduced to one right turn lane and the Mitchell Freeway southbound on-ramp at Stephenson Avenue has been partially reduced to one lane.
These changes are part of ongoing works to improve traffic flows, provide better local access throughout the area and increase capacity for the local transport network.
There will be signage in the area to support these changes and motorists are encouraged to follow this signage and exercise caution when moving through the area.
These changes mark significant progress, and a step towards the opening of the new Stephenson Avenue Interchange later this year.
These reductions will be in place until the new Stephenson Avenue interchange is open in late 2025.

When traffic management meets innovation
The Stephenson Avenue Extension project has recently had the exciting opportunity to take part in an automated cone truck trial, testing out the only one of its kind in WA.
The Main Roads automated cone truck is designed to deploy and retrieve traffic cones automatically, using a robotic arm. The truck stores 399 cones and can lay a cone approximately every 10 seconds. This means a kilometre of road can be delineated in approximately 7 minutes.
The truck reduces disruption to road users, increases productivity and significantly reduces the risk of injury to traffic management workers who are often in high-risk situations by laying cones next to traffic.
Trials on our project has allowed drivers to gain experience operating the truck in a controlled environment coinciding with planned lane closures on Mitchell Freeway.
This trial also enables Main Roads to compile data on the truck’s operations including timing and speed which can help improve the trucks efficiency.
The truck will predominantly be used across the Perth Metro area but will also feature on regional road projects, particularly where high speed roads are involved.
Take a look at the truck in action during the trial.
