By Catrin Jones11 May 2022

Seymour Whyte, an Australia-based Vinci Construction subsidiary, has been selected by the New South Wales Government to build the central section of the new M12 motorway linking the future Western Sydney International (Nancy-Bird Walton) Airport to the motorway network.

The contract, worth approximately AUD$373 million ($269 million), includes the construction of 7.5km of 2x2 lanes, 11 bridges, cycle and pedestrian paths, networks, Intelligent Transport Systems (ITS) and green spaces.

The project will reuse or recycle 95% of the excavated material, and 40% of recycled aggregates for the sub-base layers in addition to minimising water use on site.

The project is expected to start by mid-2022 and aims to be completed by the end of 2025 before the opening of Western Sydney International Airport in 2026. 

The construction site is said to create 760 jobs, providing opportunities for young workers, trainees, First Nations People and people from sectors affected by the Covid-19 crisis.
