In Alberta, VINCI Construction was awarded several contracts to repair and modernise motorway superstructures and bridges.

In a tough economic climate, Bitumix continued to take a selective approach to new business in the construction and maintenance of roads, public spaces and airport infrastructure. Two iconic projects aiming to facilitate mobility in the country stood out in 2025 for their scale: laying of the road surface of Puente Industrial, Chile’s longest viaduct (2.5 km), which straddles the Biobío river and will relieve congestion in the current transport system and shorten journey times for users; and the works contract on the approach roads to the Chacao bridge (Los Lagos region), South America’s longest suspen-sion bridge, which will connect the island of Chiloé to the mainland.

Seymour Whyte was awarded a number of large-scale projects, including a design-build contract for the modernisation and extension of Canberra’s wastewater treatment facilities. The work, which began in 2025 for a 10-year period, includes the design, engineering, and construction of new wastewater treatment infrastructure as well as major upgrades to existing facilities. Once completed, the plant will provide additional treatment capacity of 97,250 cu. meters of wastewater a day and improve the quality of treated water thanks to innovative membrane filtration technology. Once the entire treatment capacity of the plant comes online, it will be able to meet the needs of almost 800,000 residents in Canberra’s fast-growing communities. The joint venture handling construction (which includes VINCI Construction Grands Projets alongside Seymour Whyte) has committed to implementing a wide range of measures to protect the environment, including using low-carbon concrete blends to reduce carbon emissions, reusing 90% of materials on site, powering site facilities entirely with renewable energy, and relying exclusively on recycled water for construction activities.
Seymour Whyte is also involved in strengthening the Scrivener Dam in Canberra and replacing a bridge on the Wellington Dam near Worsley in Western Australia.
In the ever-dynamic road construction sector, the company won several large contracts, covering work on the North East Link in Melbourne (one additional lane in each direction, a new dedicated busway and shared-use paths, engineering structures and upgraded noise walls), as well as the construc-tion of a 4.4 km section of the South package of the Coomera Connector Stage 1 project in the Gold Coast, which will ease congestion on the M1 Pacific Motorway and support the region’s rapid population growth. Other new contracts include upgrades to a 1.3 km section of the M5 motorway in Sydney and the Youngs Crossing Road in Moreton Bay, which involves 1.1 km of roadworks and the construction of a new flood-resilient bridge over the North Pine river.
Seymour Whyte also carried out a number of major projects to support the expansion of Western Sydney, including delivering the M12 motorway and a civil and building works package for the new Western Sydney International airport. In Queensland, the company completed the widening of a 5 km section of the M1 Pacific Motorway between Palm Beach and Tugun.
New Zealand
VINCI Construction finalised its acquisition of SOL Group, which operates a recycling centre for deconstruction materials and a quarry in Christchurch, along with a mobile crushing business throughout the South Island, and of Wharehine Construction, a company established 70 years ago in Wellsford that offers civil construction and road maintenance services and operates five quarries. The two acquisitions will increase VINCI Construction’s foothold in the country and further vertical integration of HEB Construction.
HEB Construction continues to expand in road infrastructure, as well as civil, marine and hydraulic engineering. In 2025, the company delivered the Te Ahu a Turanga–Manawatū Tararua Highway (11.5 km, four lanes), restoring a vital link between Woodville and Ashhurst carrying 9,000 vehicles a day, of which 10% are heavy vehicles. The project scope includes major engineering structures, such as the widest balanced cantilever bridge in the southern hemisphere and an eco-viaduct over protected wetland incorporating a novel seismic system. Regional biodiversity has been preserved through a number of major environmental measures involving 1.8 million native plants, 4.5 km of constructed streams and the reintroduction of 3,000 fish.
An 11.5 km motorway providing a vital link between Woodville and Ashhurst, New Zealand, has opened to traffic following completion of works incorporating extensive environmental measures to protect biodiversity.
