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
