M4-M5 Link Rozelle Interchange

Also referred to as M4-M5 Link Rozelle Interchange and Iron Cove Link.

Tunnels connecting the mainline tunnels with the other sections of the road network via Rozelle.

Stage one- construction of the M4-M5 Link Tunnels tunnels between the New M4 at Haberfield and the New M5 at St Peters and stub tunnels to the Rozelle interchange. The contractor on this stage is Lendlease Samsung Bouygues Joint Venture (LSBJV). This stage is being managed by WestConnex

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 Roads and Maritime Services.

The Rozelle Interchange and Iron Cove Link is the part of the M4-M5 Link and will provide a new underground motorway interchange to City West Link and provide an underground bypass of Victoria Road between Iron Cove Bridge and Anzac Bridge, with links to the future 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

The M4-M5 Link project received NSW planning approval in April 2018.  

The following design changes are being proposed to the design and construction of M4-M5 Link Rozelle Interchange as described and assessed in the 2017 EIS.

The Crescent overpass and active transport links modification proposes the following:

• The addition of a new elevated overpass

• Realignment of the pedestrian and cyclist Green Link connecting the new park at Rozelle Rail Yards to the Rozelle Light Rail Station

• The addition of a new pedestrian cyclist bridge connecting the new park to the Rozelle Bay foreshore

• Reconfiguration to the intersection of The Crescent/Johnston Street/Chapman Road.

The modification report was on exhibition and available for community comment in September 2019. A submissions report is currently being prepared with determination. The community guide provides a summary of the changes and impacts described in the Modification report. To access the full Modification report, please visit the NSW Department of Planning, Industry and Environment site.

The Iron Cove ventilation undergrounding modification proposes the following:

  • Moving above ground buildings underground
  • Tunnelling from Iron Cove.

The modification was on exhibition and available for community comment in December 2019. A submissions report is currently being prepared for determination. The community guide provides a summary of the changes and impacts described in the Modification report.
