Tonkin Highway and Dunreath Drive Interchange​

Modified and upgraded the busy interchange near Perth Airport to reduce queuing on Tonkin Highway exit ramps during peak periods.
Tonkin Highway and Dunreath Drive <em>Interchange​</em>

Modifications to the busy interchange of Tonkin Highway and Dunreath Drive will improve traffic flow and road user safety when entering the busy Perth Airport precinct. 

More than 14,000 vehicles previously exited Dunreath Drive daily, and this number increased with the opening of the Costco store. 

Work included: 

  • Removal of the eastern roundabout on Dunreath Drive, within the airport estate 
  • Transforming the exit from Tonkin Highway southbound to Dunreath Drive eastbound into a dedicated turning lane 
  • Installing traffic signals on Dunreath Drive’s western roundabout​ to help manage traffic flow during peak hours
