Sydney’s population is expanding. To support the ongoing growth in movement of passengers and freight, Transport for NSW developed the Sydney Gateway – A new road project that provides a missing link connecting the Sydney (Kingsford Smith) Airport with the Sydney motorway network.
Sydney Gateway links Sydney Airport’s international and domestic terminals to the Sydney Motorway network via the WestConnex St Peters Interchange, enhancing access to the Airport and Port Botany precinct, reducing traffic and congestion on the local road network, and expanding capacity and efficiency for moving people and freight.
Working in Joint Venture, WSP reviewed concept designs, identifying and resolving technical challenges, prepared reference designs, undertook field studies and environmental assessments and created a combined Environmental Impact Statement (to satisfy NSW planning requirements) and a Major Development Plan (to satisfy Commonwealth planning requirements) for the project.
The reference design, the Environment Impact Statement and Major Development Plan and a response to the Submissions Report is now complete. WSP also assisted Transport for NSW with ongoing technical/environmental advice and services that de-risked project delivery and provided contracting support.
Creating lasting benefits for Sydney
The Sydney Gateway transforms journeys to and from Sydney Airport to west and southwest Sydney, the M5, and the Eastern Distributer, making them easier, faster and safer.
Since completion, Sydney Gateway:
- Has the capacity to transport 100,000 vehicles a day, catering for forecasted growth in passenger and air freight.
- Provides additional capacity by widening Qantas Drive from two to three lanes in each direction.
- Reduces cars and trucks on local roads – returning local streets to local communities.
- Improves travel times to the airport precinct and Port Botany.
In 2025, Sydney Gateway was recognised as a Finalist in Infrastructure Partnerships Australia’s National Infrastructure Awards.
