Leach Highway and Welshpool Road Interchange

We are building a new grade separated interchange to improve safety and efficiency. Planning is underway and construction is expected to start in 2021.
Leach Highway and <em>Welshpool Road Interchange</em>

We are planning to build a new interchange at one of Perth’s most congested intersections in Welshpool.

The preliminary concept for the project includes a:

  • Grade separated interchange at Leach Highway and Welshpool Road with Leach Highway travelling over Welshpool Road;
  • New road bridge for Leach Highway over the Armadale/Thornlie rail line.
