Vinci to build motorway to future Sydney airport

Seymour Whyte, an Australian subsidiary of French contractor Vinci, has been selected by the government of New South Wales (NSW) to deliver a €255m section of the M12 motorway in Sydney.

When completed, the M12 will link Western Sydney International Airport at Badgerys Creek to the city’s motorway network.

Seymour Whyte’s 7.5km section of a four-lane road involves linking Badgerys Creek and Duff Road, Cecil Hills and local access roads. The scope includes the construction of 11 bridges as well as cycle and pedestrian paths, networks, earthworks, pavements and storm drainage.

The project will reuse or recycle 95% of the excavated material, and will use recycled aggregates for the sub-base layers.

Steve Lambert, Seymour Whyte’s chief operating officer, said: “The M12 Motorway project plays a key role in supporting integrated transport in the region, capitalising on the economic benefits from developing the Western Sydney International Airport at Badgerys Creek.

“The project will play a vital role in connecting Western Sydney’s current and future local residential, commercial and industrial areas to the transport corridors of the M4, M5 and M7 motorways and the Northern Road.”

Work on the M12 is due to begin in the summer and be completed before Western Sydney International Airport opens in 2026.

When operational, it’s estimated that 52,000 vehicles a day will use the motorway.
