The Sydney Gateway is a major road interchange between the WestConnex and the airport terminals of Sydney Airport, and includes a pair of arch bridges over the Alexandra Canal and an eastbound flyover connecting Qantas Drive to the domestic terminal. It connects the Sydney Motorway network with the Sydney Airport and Port Botany precincts via the St Peters Interchange. The project provides significantly improved road links between the Airport, CBD and Port Botany, whilst reducing congestion.

Construction began in early 2021 and sections of the interchange were progressively opened from November 2023. The interchange opened on 1 September 2024. It was originally planned to fully open in late 2023 in conjunction with the connecting M4–M8 Link, the latter of which opened earlier in January 2023.

The Sydney Gateway was constructed in conjunction with the duplication of the nearby Port Botany railway line by the Australian Rail Track Corporation.
