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.
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.
