Gateway WA

Principal: Main Roads WA
Location: Kewdale  WA, Metro
Status: In Progress

The Gateway WA Perth Airport and Freight Access Project is the largest infrastructure project ever undertaken by Main Roads WA. This billion-dollar project involves a major upgrade to the road network surrounding Perth Airport and the freight and industrial hubs of Kewdale and Forrestfield. It focuses primarily on Tonkin Highway, between Great Eastern Highway and Roe Highway, and Leach Highway, between Orrong Road and Perth Airport. Early works packages began on-site in February 2013 in preparation of the main construction effort which is scheduled to commence in mid 2013. The entire Gateway WA upgrade is expected to be completed by 2017, ahead of the planned consolidation of the domestic and international terminals at the Perth Airport.

The project includes:

  • A major freeway-to-freeway interchange at Tonkin Highway-Leach Highway, including a new primary access road to the consolidated airport terminal;
  • A new interchange at Tonkin Highway-Horrie Miller Drive-Kewdale Road;
  • A new interchange at Leach Highway-Abernethy Road;
  • Upgrading 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;
  • Upgrading of the existing Tonkin Highway-Roe Highway interchange to a partial freeway to freeway interchange;
  • Upgrading Tonkin Highway between Great Eastern Highway and Roe Highway to six lanes; and
  • A new interchange at Boud Avenue (subject to further funding negotiations).
