​​​​​​​​​​​​Tonkin Highway Corridor

Roe Highway to Kelvin Road

We are widening a 6 km section of Tonkin Highway to reduce congestion. Planning and development is currently underway.
Cars driving along Tonkin Highway


From 2014-18 there were 140 crashes at Tonkin Highway and Hale Road intersection. Additionally, 80 per cent of total crashes on the Tonkin Highway were rear-end incidents - which exceeds the Perth metropolitan average of 45 per cent.

We are planning to upgrade this critical section of the State’s transport network by upgrading Tonkin Highway between Roe Highway in Kewdale and just south of Kelvin Road in Orange Grove. 

We are planning to:

  • Widen the highway from four to six lanes
  • Upgrade the intersections at Hale Road, Welshpool ​​Road and Kelvin Road
  • Build new facilities for pedestrians and cyclists along the corridor with links to the local cycle network
