WestConnex is being financed and delivered by Sydney Motorway Corporation (SMC) established by the NSW Government.
WestConnex/ It is part of an integrated transport plan that aims to ease congestion in Australia’s largest city, create jobs and connect communities while supporting Sydney’s long-term economic and population growth.
WestConnex has already widened the M4 highway from Parramatta to Homebush and created a faster way to bypass 28 sets of traffic lights on Parramatta Road. It has also created smoother road surfaces and new access points to the M4, and lengthened on- and off-ramps at the King Georges Road M5 interchange, providing more capacity and reducing congestion for motorists.
It will also extend the M4 highway via twin underground ventilated tunnels between Homebush and Haberfield, double road capacity along the M5 East corridor, join underground routes via the M4–M5 Link tunnel, provide a western bypass of Sydney’s Central Business District and connect to the future Western Harbour Tunnel, Beaches Link and F6 extension.
AECOM was engaged by the WestConnex Delivery Authority (the predecessor to the SMC) to provide environmental services for the M4, including preparing an Environmental Impact Statement, Submissions Report and Preferred Infrastructure Report for each of the three WestConnex stages, and to secure environmental planning approval for the project.
AECOM is currently engaged by SMC as technical and environmental advisor to develop the reference design for the M5 project, provide technical support to the Design and Construct tender procurement process, and secure environmental planning approval. AECOM is also currently engaged by SMC as the technical and environmental advisor to develop the reference design for the M4–M5 Link project and to secure environmental planning approval.
