Rozelle Interchange, including the Iron Cove Link is now open

The final stage of WestConnex, Rozelle Interchange, opened to traffic in November 2023. Rozelle Interchange has transformed how you travel across Sydney with motorists able to save up to 19 minutes on a trip between Parramatta and the Sydney CBD (during morning peak) using the M4 and the new Rozelle Interchange.

Rozelle Interchange has linked the M4 to the Anzac Bridge and the M8 to the City West Link and Victoria Road. Rozelle Interchange also includes a toll-free bypass of Victoria Road, known as the Iron Cove Link and links to the future Western Harbour Tunnel.

Rozelle Interchange and Iron Cove Link have been constructed by John Holland and CPB Contractors Joint Venture, with the delivery managed by Transport for NSW.

Tunnels connecting the mainline tunnels with the other sections of the road network via Rozelle. The M4-M8 Link (formerly known as the M4-M5 Link project) received NSW planning approval in April 2018.

Stage one - construction of the M4-M8 Link Tunnels between the New M4 at Haberfield and the M8 at St Peters and stub tunnels to the Rozelle Interchange. The contractor on this stage is Acciona Samsung Bouygues Joint Venture (ASBJV). This stage is being managed by WestConnex | Transurban.

Stage two - construction of the Rozelle Interchange and Iron Cove Link. The contractor on this stage is John Holland and CPB Contractors Joint Venture. This stage is being managed by Transport for NSW.

The Rozelle Interchange and Iron Cove Link will provide a new underground motorway interchange to City West Link and provide a toll-free underground bypass of Victoria Road between the Iron Cove Bridge and the Anzac Bridge, with links to the approved Western Harbour Tunnel.

The interchange in Rozelle will be mostly underground and located at the site of the old Rozelle Rail Yards. By building the interchange mostly underground, the project will deliver new active transport options in Rozelle and up to 10 hectares of new open space in the future Rozelle Parklands

Rozelle Parklands Working Group

The Rozelle Parklands is up to 10 hectares of public parkland and open space. The Rozelle Interchange project has prepared an Urban Design and Landscape Plan (UDLP) in consultation with Inner West Council, the community and affected landowners and businesses. The UDLP determined items including; landscaping, tunnel portals, tunnels, service buildings, bridges, retaining walls, pedestrian and cyclist access, lighting and wayfinding, heritage, monitoring and maintenance.

While the Rozelle Interchange UDLP includes provision for an open space within the Rozelle Parklands precinct, it does not determine the recreational and sport use or maintenance for facilities not described in the UDLP.

Transport for NSW (TfNSW) has completed consultation with a broad range of stakeholders to ensure the Parklands are used in a fair, productive, sustainable and sensitive way for the Rozelle, Lilyfield, Balmain and Annandale community to meet the diverse needs of the community.

The Rozelle Parklands Working Group (RPWG) was established to manage this consultation and made recommendations to TfNSW under the Terms of Reference.

The RPWG Recommendations Report has been finalised and was presented to the Minister for Transport in mid-2021. 

RPWG forum 

The Working Group was established to determine the optimal uses for the Rozelle Parklands that includes the recreation and sport overlay (including any required facilities) for the Parklands and to ensure all perspectives were considered across government, Council, community and relevant groups, to provide the best outcome for the local community.

The Working Group provided a forum for collaboration between group members to enable a fair, sustainable, productive and sensitive outcome.

Environment and planning

Urban Design and Landscape Plan

The Urban Design and Landscape Plan (UDLP) outlines the urban design principles and objectives for the Rozelle Interchange project (the Project), including details of the transformation of the former Rozelle Rail Yards into a new open green space of up to ten hectares, similar in size to Victoria Park near Sydney University.

When completed the future Rozelle Parklands will have a wetlands with a boardwalk, picnic and BBQ areas, play equipment, pedestrian and cyclist paths and green fields for leisure activities. To walk through the features view the flythrough video

In May 2021, the Rozelle Interchange Project Urban Design and Landscape Plan was approved by the Department of Planning, Industry and Environment.

The UDLP was on public display from 10 August till 6 September 2020. The public was directed to our virtual Community Centre to view the full plan, access the interactive map, read the Community Guide and watch an information session.

All feedback and submissions were carefully reviewed and considered for final design. The Community Guide summarises the feedback and comments we received.

The Crescent overpass and active transport links Modification – Design Amendment 

The Modification was approved by the Department of Planning, Industry and Environment on 30 September 2020. See the Response to Submissions Report on the Department’s Planning Portal.

In August 2019, changes were proposed to the design and construction of the M4-M5 Link (Rozelle Interchange) as described and assessed in the 2017 Environmental Impact Statement (EIS). These changes were described in The Crescent Overpass and active transport links Modification Report (August 2019). Transport for NSW carried out a number of community and stakeholder workshops during the exhibition of this report and as a result of the feedback and the formal submissions received, we reviewed the design we initially proposed. A design review process involved an investigation with the commissioning of a Special Design Review Panel, additional community and stakeholder workshops and additional traffic and pedestrian modelling and assessment. 

In May 2020, the improved Modification design was on exhibition through a Design Amendment Report and the community were invited to make a submission. The submissions and our response during the last exhibition were also made available.
