Project completion was marked on 21 September 2021, with remaining traffic management removed and all lanes in operation. The result has been immediate congestion relief, improved journey times and better safety outcomes at what had previously been one of Perth's busiest intersections.
More than 3 km of shared path was constructed as part of this project, which offers better connectivity between Forrestfield, Maida Vale and High Wycombe.
- Construction of a grade-separated intersection at the Roe Highway and Kalamunda Road intersection including a new bridge, two roundabouts and on and off ramps
- Lowering Roe Highway to pass beneath Kalamunda Road. This will minimise noise and visual intrusion for the surrounding residential area
- Creation of a shared path on the eastern side of the highway and on Kalamunda Road, with local links for pedestrians and cyclists. The path will then extend to Berkshire Road and complete a missing link in the Shared Path network along Roe Highway
- New drainage, street lighting and other supplementary works
