Dedicated exit lanes

The problem

Exiting the freeway can be a daunting task for some, resulting in significant traffic disruptions as drivers try to change lanes to position themselves correctly.

To ease some of the confusion and make exiting easier, we analysed major conflict points along the freeway and identified opportunities to provide dedicated exit lanes at key locations.

The solution

Completed in April 2016, four clearly marked exit lanes have removed merge points to allow traffic to exit the freeway without causing disruption to the flow of traffic.

The dedicated exit lane for Karrinyup Road has resulted in a 5 km/h (15 per cent) increase in freeway speeds between Wellington Street and Karrinyup Road in afternoon peak.
