Tonkin Highway between Collier Road and Great Eastern Highway

We are upgrading Tonkin Highway – between Collier Road and Dunreath Drive - as we work to deliver a high standard north-south transport link in Perth’s eastern corridor.

The Tonkin Gap Project will eliminate the current ‘gap’ where highway capacity reduces between Guildford Road and Great Eastern Highway. We will be increasing the number of lanes and upgrading interchanges as well as improving connectivity for pedestrians and cyclists.
