  • a new interchange at Tonkin Highway-Horrie Miller Drive-Kewdale Road;
  • a new interchange at Leach Highway-Abernethy Road;
  • upgrade of Leach Highway between Orrong Road and Tonkin Highway to an expressway standard and associated upgrades to local roads and intersections in the Kewdale area,
  • a principal shared path along Tonkin Highway and Leach Highway;
  • stage one of a new freeway-to-freeway interchange at Tonkin Highway-Roe Highway;
  • upgrade of Tonkin Highway between Great Eastern Highway and Roe Highway to six lanes; and
