Tonkin Highway Gap

The WA Government is undertaking improvements to the Tonkin Highway corridor. The Tonkin Highway is a 44-kilometre north-south highway and partial freeway in Perth, Western Australia, linking Perth Airport with the city's north-eastern and south-eastern suburbs.

  • new bridges over the Swan River, Guildford Road, Railway Parade, the Midland Line railway and Dunstone Road
  • upgrades to the Guildford Road and Great Eastern Highway interchanges
