Western Harbour Tunnel and Beaches Link

Western Harbour Tunnel and Beaches Link

Western Harbour Tunnel and Beaches Link is a proposed state significant motorway that will make it easier, faster and safer to get around Sydney. Delivering the Western Harbour Tunnel and Beaches Link will improve journey times and reliability for public transport, freight and private vehicles as well as alleviate pressure on Sydney CBD, Sydney Harbour Bridge, Anzac Bridge and the Western Distributor. Once complete, the project will provide a motorway link between the Northern Beaches and the rest of Sydney.

Roads and Maritime Services (a NSW Government agency) continue to use transport modelling of various types and scales to inform development of Western Harbour Tunnel and Beaches Link.

SCT Consulting team members have extensive experience in partnering with NSW Government and contractors to deliver successful motorway projects. We were traffic modelling leads for the Leighton Samsung John Holland Joint Venture bid on WestConnex Stage 1B, which developed an innovative ramp configuration for the Concord Road interchange – a design which would be part of the reason that the joint venture won the contract to build the motorway. We also have extensive traffic modelling experience in a broad range of projects, including the Northern Beaches Hospital and Sydney Airport Master Plan. We have the unique advantage of being able to communicate complex traffic modelling to technical and non-technical audiences.

SCT Consulting were engaged as a part of a team to lead operational traffic modelling packages for the Beaches Link and the Gore Hill Freeway connection, including analysis of strategic model outputs, preparation of operational traffic modelling in Vissim, meticulous consideration of calibration and validation testing to ensure models conformed to existing conditions and working collaboratively with the client to deliver quality work on time. Traffic modelling outputs  are used as critical inputs to the project development process, seeking to maximise the benefits of the new infrastructure while minimising impacts to the surrounding environment. SCT Consulting worked directly with subject matter experts in Roads and Maritime to ensure that the modelling methodology fully satisfied the client’s requirements and expectations.

The Western Harbour and Tunnel Beaches Link government project manager stated in his review of our performance, that “the SCT team has been highly responsive and flexible, while continuously producing high quality deliverables.”
