The Sydney Gateway is a major road interchange between the WestConnex and the airport terminals of Sydney Airport. Construction began in early 2021 and is expected to open in December 2024. The Sydney Gateway will provide a high-capacity connection from Sydney Airport and Port Botany to the new Westconnex St Peters Interchange once completed. Sydney Gateway is part of the NSW Government’s vision to complete the missing links in the motorway network, improve traffic flow and reduce travel times.
Sydney Gateway will strengthen Sydney’s position as a global city, by expanding and improving the existing road and freight rail networks. Importantly, Sydney Gateway will provide a new route for around 10,000 trucks a day. This will divert trucks from local streets in Mascot by providing an alternative route, reducing travel times and congestion, and returning local streets to the community.

JDK was engaged in the geotechnical site investigation work under the management of Coffey/Tetra Tech. JDK was able to undertake geotechnical investigation work autonomously alongside site safety and documentation management protocols. This effectively streamlined the delivery of Stage 2 of the investigative works of the project.
