The Sydney Gateway will provide a high capacity connection from Sydney Airport and Port Botany to the new Westconnex St Peters Interchange once completed.
The project will be delivered in two stages (Stage One and Stage Three).
Stage One will provide a new road connection linking the Sydney motorway network at St Peters Interchange with Sydney Airport’s International Terminal and Qantas Drive. This will include:
- St Peters Interchange Connection – a new elevated section of road extending from St Peters interchange to the Botany Rail Line, including an overpass over Canal Road
- Terminal One Connection – a new section of road connecting Terminal One with St Peters interchange connection, including a bridge over Alexandra Canal and an overpass over the Botany Rail Line
- Qantas Drive Upgrade and Extension – widening and upgrading Qantas Drive to connect Terminals Two and Three with the St Peters Interchange connection, including a high-level bridge over Alexandra Canal
- Terminal Links – two new sections of road connecting all three Terminals, including a bridge over Alexandra Canal, and
- Terminals Two and Three Access – a new elevated viaduct and overpass connecting Terminals Two and Three with the upgraded Qantas Drive.
Stage Three is an arterial road connection and flyover to Sydney Airport’s Domestic Terminals, including improvements to existing roads to reduce congestion and improve connectivity to Sydney Airport Domestic Terminals and towards Port Botany. Stage Three will consist of:
- A new section of road and an overpass connecting Sydney Airport’s northern lands on either side of the Botany Rail Line (the northern lands access), and
- A new section of road, including a signalised intersection with the Terminal One connection and a bridge, connecting Sydney Airport’s existing and proposed freight facilities on either side of Alexandra Canal (the freight terminal access).
Stage Two is the Port Botany Rail Duplication, which is being separately delivered by the Australian Rail Track Corporation.
