The Rozelle Interchange is an underground motorway interchange in Sydney, New South Wales, Australia. It was built as part of WestConnex and opened to traffic on 26 November 2023.[1] The interchange includes a toll-free bypass of Victoria Road between the Iron Cove Bridge and the Anzac Bridge known as the Iron Cove Link.[2]

The interchange is located at the site of the former Rozelle Rail Yards.[2] It is one of largest and most complex underground junctions in the world. It has three storeys of tunnels, with the deepest being 65 metres (213 ft) below ground.[3]

The interchange will be the southern terminus of the under-construction Western Harbour Tunnel, which will be completed in 2028. Stub tunnels for the new tunnel were built during the construction of the interchange. On the surface above the underground interchange is a parkland known as Rozelle Parklands.

The interchange has been described as "Australia's most complex underground junction" and a spaghetti junction.[4]
