M12 Motorway (In development)

The NSW Government is addressing congestion, improving safety and providing more choice for how you move around all of Sydney.

The M12 Motorway would provide connections between Western Sydney International Airport and the surrounding Aerotropolis to other employment areas and population centres via the Sydney motorway network. It would provide high-speed motorway-standard access from the M7 Motorway and the Northern Road and reduce traffic on Elizabeth Drive and at key intersections.

Transport for NSW is seeking approval to construct and operate the M12 Motorway which would run between the M7 Motorway at Cecil Hills and the Northern Road at Luddenham and would be opened to traffic prior to opening of the Western Sydney International Airport.

Western Harbour Tunnel and Warringah Freeway Upgrade

A 6.5km tunnel that will connect the Warringah Freeway at North Sydney with the Rozelle Interchange, the M4 and the M5 via a tunnel beneath Sydney Harbour. It will be a much needed third Sydney Harbour crossing and offer a western bypass of the Sydney CBD.

The Warringah Freeway Upgrade would involve renovation of 4km of the freeway to provide connections for the Western Harbour Tunnel and Beaches Link and significantly the improve the efficiency one of Australia’s busiest and most complex road corridors.


Project stage:

Reference design: A highly detailed civil-engineered design is shown to stakeholders and the community. Is shows ACTUAL project alignments, portal and ventilation outlets. It details HOW community feedback has been used to refine the project’s design.

Benefits

  • Create a 3rd crossing of Sydney Harbour
  • A new western bypass of the CBD
  • Take pressure of Sydney Harbour Bridge and Tunnel
