What's happening
Perth’s latest Smart Freeway is progressing on the Mitchell Freeway southbound between Hester Avenue and Vincent Street. Construction works are underway with day and night works requiring intermittent lane and full freeway closures, full and partial ramp closures and detours.
Works include:
- Construction of the additional lane between Warwick Road and Hepburn Avenue.
- Construction of the concrete barrier along the median.
- Shifting traffic onto the median and right lanes, creating a safe space to enable construction works to occur along the left lane and verge.
- Ramp widening works at Whitfords Avenue and Ocean Reef Road to install Intelligent Transport System technology, street lighting, drainage and barriers.
- Changes to the Vincent Street on-ramp.
Path upgrades
Work is under way to construct the Principal Shared Path (PSP) between Ocean Reef Road and Warwick Train Station, with existing sections being upgraded to meet current access and mobility standards.
Paths detours are in place to ensure the safety of path users, road users and our workforce. Signage displaying detour route maps is located at shared path entry points and work locations. Directional signage will guide cyclists through the detour routes.
The Ocean Reef Road to Warwick Train Station PSP is anticipated to be completed early 2024.
Works progressing well
Works to install smart technology on entry-ramps from Hester Avenue to Vincent Street is well underway, and temporary traffic management at these sites can be anticipated until the end of 2023.
We’re continuing to explore innovative design solutions to retain vegetation and increase areas for urban landscaping and a comprehensive landscaping and revegetation plan is being finalised.
Works will soon begin at the Hutton Street on-ramp in Osborne Park and include widening of the on-ramp and improvements to Cape Street, Hector Street and McDonald Street.
During the works, there will be traffic, pedestrian, cyclist and e-vehicle detours. Please allow additional time for travelling through the detour, drive to the conditions, and follow signage and directions from traffic controllers.
