The work will be carried out by a 50:50 joint venture of Seymour Whyte - a Vinci Construction subsidiary based in Australia – and John Holland. Another Vinci Construction subsidiary, Freyssinet, is also involved in the project to provide bridge-launching expertise.

Sydney Gateway

Sydney Gateway is designed to reduce congestion and optimise the city’s motorway network by connecting the newly opened St Peters Interchange to Sydney Airport and Port Botany. The contract involves constructing 5km of new and upgraded roads around the airport precinct. It includes an interchange connection, 19 bridges and a dedicated flyover to the airport terminals as well as pathways for cyclists and pedestrians.

John Holland CEO Joe Barr said that the project will support up to 4,000 jobs and cut travel times for commuters using Sydney roads, with a capacity to carry 100,000 vehicles a day.

Seymour Whyte managing director and CEO John Kirkwood said: “We are committed to working closely with our local suppliers, local communities and the government to deliver this important project safely and efficiently.”
