Stephenson Avenue Extension

The Stephenson Avenue Extension Project is part of the City of Stirling’s broader plan to transform the Stirling City Centre – an area bounded by Karrinyup Road, along Cedric Street and Ellen Stirling Boulevard to Scarborough Beach Road. 

The project will extend Stephenson Avenue from Scarborough Beach Road to the Mitchell Freeway and Cedric Street. It will also connect key activity hubs, including Westfield Innaloo Shopping Centre, the Osborne Park industrial area and the Stirling City Centre.

We are also delivering the Stirling Bus Interchange upgrade on behalf of the Public Transport Authority (PTA). The upgrade consists of increasing the capacity from an 18-stand bus station to a modern 30-stand bus interchange along with the construction of a new pedestrian access bridge between Stirling Station and the southern car park.

By co-ordinating with the Public Transport Authority for the Stirling Bus Interchange upgrade and the Stephenson Avenue works, we will be able to streamline the design and construction process minimising disruption to motorists, bus and rail passengers and the surrounding community.
