The Western Harbour Tunnel & Beaches Link is a planned north-south motorway along the current alignment of Wakehurst Parkway between Warringah Road, Frenchs Forest and the WestConnex motorway in Sydney.[1] The four-lane motorway is planned to be 14 km long and to be built (with both State and Federal funding).[2] It is intended to provide direct access from the Northern Beaches to the Inner West at Rozelle.


The Western Harbour Tunnel & Beaches Link is aimed at reducing the level of traffic congestion in the greater Sydney area. The Sydney Harbour Bridge and Sydney Harbour Tunnel corridor currently carry 80 percent of all vehicles crossing Sydney Harbour and the Parramatta River, greatly increasing traffic congestion.[2] The Government of New South Wales has pledged $77 million in funding to evaluate the design and construction feasibility of the project. The design phase began in early April 2017[2] and is scheduled to be completed by mid-2018.[3]


The forecast cost is $14bn.[4]
