Western Harbour Tunnel and Beaches Link Program is a major transport infrastructure proposal that will make it easier, faster and safer to get around Sydney.
Western Harbour Tunnel delivers a new crossing under Sydney Harbour and creates a western bypass of the Sydney Central Business District (CBD) to the Warringah Freeway, taking pressure off the congested Sydney Harbour Bridge, Anzac Bridge and Western Distributor. The project includes upgrading approximately four kilometres of Australia’s busiest road, the Warringah Freeway.
The Western Harbour Tunnel includes over six kilometres of tunnels as well as upgrading over nine kilometres of surface roads. Western Harbour Tunnel will integrate with public transport, improve travel times and boost reliability for cross harbour trips and the broader network.
The Beaches Link includes over 11 kilometres of tunnels as well as upgrading over five kilometres of surface roads. It is an integrated transport solution that will improve car and bus journey times to and from the Northern Beaches. It will also provide new connections to St Leonards and Macquarie Park, linking people with jobs, education and services.
WSP, in joint venture, was engaged by Transport for NSW as Technical Advisor for the project. Our scope of work includes the preliminary environmental assessment Reference Design, project GIS services, as well as the traffic modelling for the project.
