Project Details

The work will include widening the highway from four to six lanes, and building new facilities for pedestrians and cyclists along the corridor with links to the City's cycling network.

Planning and development work is underway to improve safety and reduce delays along the heavily congested section of Tonkin Highway from Roe Highway to Kelvin Road. The project will be delivered under two contracts; the first includes the intersections along Tonkin Highway at Hale Road and Welshpool Road, and the second includes Tonkin Highway and Kelvin Road.

• Widening Tonkin Highway from four to six lanes from south of Roe Highway to Kelvin Road
• Grade separations (Tonkin Highway travelling over intersections at):
  • Tonkin Highway / Welshpool Road – Connections to and from Tonkin Highway north and south
  • Tonkin Highway / Hale Road – Partial connection with north-facing ramps (to and from the airport and Perth)
  • Tonkin Highway / Kelvin Road – Connections to and from Tonkin Highway north and south
• Median and verge barriers
• Principal Shared Path connecting to existing paths north on Tonkin Highway, including underpasses at ramps at the new intersections
• Lighting and noise walls
• Local urban design and landscaping opportunities.
