What's happening
Path upgrades
A number of path closures are in place to facilitate construction of the new shared path along Mitchell Freeway. Learn more about the locations and detours under the 'Roadworks and path closures' heading below.
A series of intermittent detours will be required to ensure the safety of path users, road users and our workforce whilst construction works are taking place.
Vegetation clearing
Removal of vegetation in the road reserve between Ocean Reef Road and Warwick Road is continuing, to enable construction of the shared path, noise walls, dedicated freeway lane from Hepburn to Warwick, emergency lane and emergency bays on the freeway.
The vegetation to be removed has been independently assessed and approval has been granted by State and Federal environment authorities.
Read more in the ‘Environment’ heading below.
Works progressing well
Construction of the new freeway lane in the median is progressing well, along with drainage works and installation of a new barrier along the rail line.Works to install smart technology on nine freeway entry-ramps from Hester Avenue to Warwick Road have commenced, with temporary traffic management in place.
We’re continuing to explore innovative design solutions to retain vegetation and increase areas for urban landscaping. A comprehensive landscaping and revegetation plan is being finalised.
In mid-2022, freeway traffic will be switched to the newly constructed median lane to allow works to commence on the verge side of the freeway.
The next ‘Smart Freeway’ is being rolled out from Hester Avenue to Vincent Street, with all 16 entry ramps to be modified with co-ordinated signals. Smart technologies will be installed from Reid Highway to Vincent Street, including 20 overhead electronic signs which can display speed reductions and let you know when a lane is closed ahead.
Detailed design is being finalised from Hester Avenue to Warwick Road for freeway ramp modifications, emergency lane and stopping bays and the shared path.
Other upgrades along the freeway include:
- Construction of an additional southbound lane from Hodges Drive to Hepburn Avenue.
- Construction of a dedicated lane from Hepburn Avenue entry ramp to Warwick Road exit ramp.
- Upgrade and build new shared paths between Ocean Reef Road and Warwick Train Station, connecting to the path adjacent to the freeway.
- Installation of safety barriers, emergency stopping bays, emergency breakdown lanes, and noise walls where required.

Noise walls
Noise monitoring was undertaken to determine the locations and heights of noise walls, in line with State Planning Policy 5.4.
As a result, we will be building 5.5 km of noise walls between Ocean Reef Road and Warwick Train Station. We are currently finalising the design. Residents who will have a wall installed on their rear boundary have been, and will continue to be, consulted with.
Read more in the Noise Mitigation Fact Sheet.
Shared path
Both new and upgraded shared paths will be constructed to create a high standard route between Ocean Reef Road and Warwick Train Station. Forming part of the State Government’s PSP Expansion Program, the path will connect to paths adjacent to Mitchell Freeway.
Learn more about what we're doing in our Shared Path Fact Sheet.Our Technical Path User Working Group has come up with some innovative designs to enable a three metre verge alongside the 8 kilometre shared path, which will be replanted with vegetation to improve community aesthetics.
We continue to work with key stakeholders to balance competing demands within the complex site constraints such as available land, sloping freeway verges, underground services, access and maintenance of the shared path, accessibility requirements in the design of the path, safety and efficiencies for the motoring public and path users, community needs, aesthetics and preferences.
Vegetation clearing
To enable construction of the new freeway ramp alignments, shared path and noise walls, the removal of vegetation in the road reserve adjacent to Mitchell Freeway southbound lanes has commenced.
The extent of vegetation clearing is varied along the freeway alignment. In some locations where the available land to construct the new infrastructure is narrow, or constrained by existing underground services, all of the existing vegetation will need to be cleared. In other locations, larger areas of vegetation will be retained because there is adequate land available to build the infrastructure.
Landscaping
To reinstate vegetation wherever possible, landscaping will be undertaken after construction activities are completed in the cooler months to ensure they adapt to the natural conditions and thrive.
The planting will comprise a mix of seeds and tubestock. To ensure similar species are used, seeds were collected along the vegetation alignment prior to construction, and stored for re-use during the landscaping program.
Community Reference Groups
Members of the community were invited to join our Community Reference Group which was established to provide a forum to facilitate and improve communication between the community, stakeholders and the project.
We make every effort to minimise impact on the surrounding environment.
Flora, vegetation and fauna surveys for the project were completed in 2019 and 2020 to help inform the planning. The design for this project has maximised the retention of existing vegetation wherever possible in the constrained areas.
However, clearing of vegetation is required along the infrastructure corridor within our road reserve. Most of this was planted by us when the freeway was constructed, with the intention of removing it when freeway expansion was required.
Environmental approvals
An environmental proposal was submitted for a section of the works adjacent to the freeway in November 2020 to Commonwealth Department of Agriculture, Water and the Environment (DAWE) for approval. The proposal was considered a controlled action under the Environmental Protection and Biodiversity Conservation Act 1999 (EPBC Act) in December 2020 and will be assessed under preliminary documentation by DAWE.

On 5 October 2021, the Department of Water and Environmental Regulation (DWER) approved our application for a Native Vegetation Clearing Permit, under Section 51C of the Environmental Protection Act 1986 (EP Act), to clear native vegetation for this section of the works.
To facilitate construction of the shared path and works on the Hodges Drive and Hepburn Avenue entry ramps, a small area of native vegetation will be cleared under the Main Roads state-wide clearing permit CPS818/15 issued by DWER.
In some areas the proposed clearing will require removal of patches of Black Cockatoo habitat trees and Tuart Woodlands of the Swan Coastal Plain Threatened Ecological Community.
To counterbalance these impacts the proposed clearing will be offset by the acquisition of 31.9ha of native vegetation at Lake Clifton, which includes Tuart Woodlands TEC and Black Cockatoo habitat, and is now under management by the Department of Biodiversity, Conservation and Attractions (DBCA). We are also consulting with DBCA to implement revegetation of an additional 7.1 ha of land near the project area.
