The Canning Highway northbound on-ramp has been a major contributor to traffic congestion on Kwinana Freeway.
Converting the emergency lane into a full time traffic lane means vehicles no longer need to merge into freeway traffic from Canning Highway. This will reduce congestion and keep traffic flowing more smoothly for Perth-bound vehicles on Kwinana Freeway.
To make merging easier, traffic signals have been installed on five northbound on-ramps along Kwinana Freeway.
These signals work the same as normal traffic lights, only faster. They switch quickly between green, yellow and red, allowing one car per lane to join the freeway at a time.
Managing the flow of vehicles onto the freeway makes merging easier and safer. It prevents stop-start conditions building from the merge point and helps keep freeway traffic moving.
