Sydney Gateway
The Sydney Gateway is a partially-open major road interchange between the WestConnex and the airport terminals of Sydney Airport, and includes a new pair of arch bridges over the Alexandra Canal and an eastbound flyover connecting Qantas Drive to the domestic terminal buildings. Upon completion, the Sydney Gateway will connect the Sydney Motorway network with the Sydney Airport and Port Botany precincts via the St Peters Interchange. The completed project is expected to provide improved road links between the airport and Port Botany and reduce congestion.

Construction began in early 2021 and is expected to fully open in December 2024. Sections of the project were partially open to eastbound traffic a year earlier in November 2023. The interchange was originally planned to fully open in late 2023 in conjunction with the M4–M8 Link, which ultimately opened earlier in January that year.
The Sydney Gateway was constructed in conjunction with the duplication of the nearby Port Botany freight rail line, which is being managed by the Australian Rail Track Corporation.
