The Government of New South Wales in Australia has selected Seymour White to deliver the central section of M12 Motorway. It includes a 7.5-kilometer section between Badgerys Creek and Duff Road, Cecil Hills, as well as local access roads.

The motorway will provide direct access to the new Western Sydney International (Nancy-Bird Walton) Airport and connect the airport to Sydney’s motorway network. Work on the M12 Motorway is expected to start in mid-2022 and will be completed before the Western Sydney International Airport opens in 2026.
