This project involves upgrading the intersection of Leach Highway and Welshpool Road, currently one of Perth’s most congested intersections.

Constructions works include a grade-separated interchange at the intersection with a new road bridge installed at Leach Highway over the Armadale/Thornlie rail line.

There will also be a shared path for cyclists and pedestrians along Leach Highway from Sevenoaks Street to Orrong Road, including over the Armadale rail line.

The project will also support the east-west freight link connecting Fremantle with the Kewdale and Welshpool industrial area.

Benefits

  • Improved traffic flow and efficiency
  • Significantly reduced travel times and improved road safety
