Leach Highway and Welshpool Road Interchange

Construction has started on the new interchange to improve safety and efficiency at one of Perth’s most congested intersections.
Intersection of Leach Highway and Welshpool Road

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
  • duplication of the existing Leach Highway bridge over the railway at Railway Parade and Sevenoakes Street
  • a shared path along Leach Highway from Sevenoakes Street to Orrong Road

The roundabout design provides:

  • increased safety to all road users
  • improved network capacity
  • better traffic flows

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.

The project is being delivered by the Leach Welshpool Alliance (LWA), comprising local contractors Georgiou Group Pty Ltd, BG&E Pty Ltd, Golder Associates Pty Ltd and Main Roads.
