Seymour Whyte has been selected by the NSW Government to deliver the central section of Sydney’s M12 Motorway, as part of the Western Sydney Infrastructure Plan (WSIP) road investment program.

The M12 Motorway will provide direct access to the Western Sydney International Airport at Badgerys Creek and connect to Sydney’s motorway network.

Seymour Whyte will deliver a 7.5-kilometre section of the motorway’s central package of works, between Badgerys Creek and Duff Road, Cecil Hills, including local access roads.

Seymour Whyte will build the central section of the M12 between Cecil Park and Badgerys Creek, while CPB Georgiou Group Joint Venture will deliver the western section to The Northern Road, which includes the airport interchange and Elizabeth Drive flyover.

The scope of works for the central section includes bridgeworks, earthworks, pavements, stormwater drainage, ITS, active transport / shared user paths, public utility adjustments and protection works, street lighting, property adjustments, and landscaping.

Seymour Whyte is targeting an ‘excellent’ sustainability rating from the Infrastructure Sustainability Council (ISC), through sustainable initiatives such as reusing/recycling 95 per cent of the excavated material, using recycled aggregates for the sub-base layers and minimising water-use on the site.

Steve Lambert, Seymour Whyte Chief Operating Officer, said the project would connect key transport corridors in the region.

“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,” Lambert said.

Patrick McCormack, Seymour Whyte General Manager – Central, said achieving sustainability would be a priority for the project.

“Sustainability to minimise our environmental impact is a key focus for the project. We are committed to implementing sustainable solutions to mitigate the impact of our operations and construction activities on the environment by optimising resources to move towards a circular economy, and acting for the climate,” he said.

Seymour Whyte is currently delivering the Western Sydney International Airport Landside Civil and Building package of works; and has recently delivered several Western Sydney projects, including the Narellan Road upgrade, the M4 Smart Motorway and the Yandhai Nepean Crossing in Penrith.

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. More than 52,000 vehicles a day are expected to use the new motorway.
