Leach Highway and Welshpool Road Interchange
A new interchange will be constructed to improve safety and efficiency. Construction is set to start in early-2021.

We are planning to build a new interchange at one of Perth’s most congested intersections. Used by around 50,000 vehicles per day, Leach Highway and Welshpool Road is currently ranked as the worst intersection across Western Australia for crash frequency.
The project will deliver:
- a new bridge taking Leach Highway over Welshpool Road to create a grade-separated interchange
- a new roundabout at the current Leach Highway and Welshpool Road intersection
- a shared path along Leach Highway from Welshpool Road to Orrong Road
The project will support the east-west freight link connecting Fremantle with the Kewdale and Welshpool industrial area. It will also provide access to many industries and businesses, as well as connecting the residential suburbs of East Cannington and Queens Park with Victoria Park via Albany Highway.
