The Transport for New South Wales in Australia has announced plans to launch a request for expression of interest for the development of Western Harbour Tunnel which will stretch from the Warringah Freeway at Cammeray, across Sydney Harbour, to the WestConnex interchange at Rozelle.

The authority is also planning to launch expressions of interest for the Warringah Freeway Upgrade. The upgrade will increase safety for motorists, make public transport more reliable and deliver better active transport links along four kilometres of the Warringah Freeway.
