Westconnex M4 – M5 Link

Construction of tunnels and a new road link between the M4 Haberfield and the M5 at St Peters via Rozelle. The M4-M5 Link project includes an interchange at Rozelle with provision for a future connection to the Western Harbour Tunnel and BeachesLink. It also includes an underground tunnel from the Rozelle Interchange to Victoria Road near Iron Cove Bridge known as the ‘Iron Cove Link’.
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 green space. The M4-M5 Link will also provide an additional 2.5 hectares of green space in St Peters.

Facilities for motorway operation controls and ventilation for the tunnels are also required.
