The Rozelle Interchange project and Iron Cove Link are being delivered by Transport for NSW.

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

Stage one - construction of the M4-M5 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 an underground bypass of Victoria Road between the Iron Cove Bridge and the ANZAC Bridge, with links to the proposed 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.

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 around 9.5 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.

Between 10 August and 6 September, the UDLP was on public display for submissions through our virtual Community Centre. You can still view the full plan, access the interactive map, read through the Community Guide and watch an information session on the virtual Community Centre.

Prior to the public display period, an UDLP values survey was held online for two weeks, between 20 July and 2 August. This helped the Project understand the topics that were of most interest or concern to the community.

With the exhibition period now closed, we are collating all submissions received. These submissions are being categorised by topic and will be reviewed as part of the next step in the UDLP design process.

All feedback and submissions will be reviewed and considered for final design, where feasible. Considerations for inclusion will be made based on the standards and requirements set out for the UDLP. Where possible, changes will be made to the final UDLP, and a copy will be provided to the Department of Planning, Industry and Environment for approval.


The Crescent overpass and active transport links Modification – Design Amendment 

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 a design review and 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. To access the reports, please visit the NSW Department of Planning, Industry and Environment. 

The Community Guide provides an overview of the design review process, the proposed improvement to the Modification design and provides a summary of the issues raised in your submissions during exhibition in August 2019. 

Our Project experts presented on the refinements to the Modification design and answered questions via video link on Thursday 7 May 2020.

Iron Cove ventilation underground modification

The Modification was approved by the Department of Planning, Industry and Environment on 28 July 2020. See the details on the Department’s Planning Portal.

As part of the Modification some of the ventilation buildings that were originally intended to be built on the surface have been moved underground. This means there will be extra ventilation tunnels in the Iron Cove area. Please visit the Tunnel Tool for more information about the tunnel locations and depths.

The Modification was on exhibition and available for community comment in December 2019. The Response to Submissions Report is available to view.
