Vinci drives off with three road construction contracts in Australia

Delivered through its local subsidiary Seymour Whyte, the projects include a major motorway extension on the Gold Coast, a flood-resilient bridge scheme in Queensland, and the upgrade of a key arterial road in western Sydney.

The largest of the three is a €229m (A$410m) contract to build a 4.4km section of the Coomera Connector between Coomera and Nerang on the Gold Coast. Awarded by the Queensland Department of Transport and Main Roads, the project includes bulk earthworks, hard rock excavation, a new interchange, and three bridges, one which will span 300m across the Nerang River.

In Queensland’s Moreton Bay region, Seymour Whyte will deliver a €48m (A$86m) upgrade to Youngs Crossing Road, including a 212m bridge over the North Pine River. The project is designed to improve flood resilience and will involve construction of retaining walls, noise barriers, and the upgraded sewer and watermains.

Meanwhile, the third project, commissioned by Transport for New South Wales, involves the design and construction of a €154m (A$277m) upgrade to the westbound carriageway of the M5 motorway in Sydney. Work includes widening 1.3km of the corridor, building a new three-lane overbridge at Moorebank Avenue, and creating a new two-lane off-ramp to the Hume Highway.

Vinci reported €1.4bn in revenue from its Australian operations in 2024, with €1.2bn generated by its construction activities. The group said the latest wins highlight its strategy to expand its presence in the country’s transport infrastructure sector.
