Smart Freeway - Mitchell Southbound

Construction activities kick off

From Monday 28 June, traffic will be progressively shifted to a temporary alignment from Hester Avenue to Warwick Road. New lines will be painted and traffic barriers installed, which will allow us to start constructing a new third lane in the median. The changed conditions will be in place for several months.

Read about the impacts under the "Roadworks" section below.

Existing line markings will be removed during night works, and nearby residents may experience noise as machinery moves along the freeway. We apologise for the disruption this may cause.

Finalising the detailed design 

Detailed design is being finalised from Hester Avenue to Warwick Road for freeway ramp modifications, emergency lane and stopping bays and the shared path. Some of the activities include:

• Geotechnical and site investigations
• Environmental approvals
• Noise monitoring and assessment
• Consultation with key stakeholders

Currently in procurement 

Three consortia have been shortlisted to submit design and construction proposals for the roll-out of smart technologies from Reid Highway to Vincent Street:

• CPB, GHD, UGL and SAGE
• Intelligent Freeways Alliance (NRW, Lendlease Services, WSP)
• SmartWays Alliance (BMD, Ventia, Arup).

A consortia is where contractors come together with their resources and expertise to deliver a project.

The contract is expected to be awarded later this year.

Reid Highway to Vincent Street

• Mid-2020: Project planning and development

• Late-2021: Contract award
• Early-2022: Anticipate construction to start
• Late-2023: Estimated completion

Freeway widening - A new lane will be added southbound from Hodges Drive to Hepburn Avenue, and a new dedicated lane added from Hepburn Avenue entry ramp to Warwick Road exit ramp, to provide a safe distance for motorists to enter or exit the freeway.

Smart technology - The next ‘Smart Freeway’ is being rolled out from Hester Avenue to Vincent Street. Modifications will be undertaken at each of the 16 entry ramps with co-ordinated signals, and incorporate Smart Freeway technologies at key locations closer to Perth CBD. These technologies will include overhead electronic signs which can display speed reductions and let you know when a lane is closed ahead.

Active transport - Both new and upgraded shared paths will be constructed to create a high standard route between Ocean Reef Road to Warwick Station.

Safety upgrades and additional works include:

• Concrete and safety barriers
• Emergency stopping bays and emergency breakdown lane
• Lighting
• Drainage
• Noise and amenity walls
• Resurfacing and line marking where required

Mitchell Freeway southbound from Hodges Drive, progressively shifting to Warwick Road

• Night works: 28 June to end of August from 7:30pm to 5am (excludes Saturdays)
• Reduced to a single lane and speed reduced to 60 km/h
• Intermittent ramp closures as required. Signed detours in place
• Works to facilitate line-marking, barrier and sign installation

Changed road conditions - ongoing from Thursday morning 1 July

• Traffic will be shifted to the emergency and left lanes
• Speed reduced to 80 km/h with reduced lane widths 

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. These surveys helped inform the planning and design of the proposal.

We also applied for a Native Vegetation Clearing Permit under Section 51C of the Environmental Protection Act 1986 (EP Act) from the Department of Water and Environmental Regulation (DWER) to clear native vegetation for this section of the works.

This Native Vegetation Clearing Permit application (CPS9225-1) is currently under assessment by DWER.

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.

• Create more reliable journey times
• Reduce congestion, particularly during morning peak
• Alleviate pressure on local roads
• Allow traffic to be managed in real-time 
• Use existing infrastructure more efficiently to cater to future demand
