M7-M12 Integration Project
The M7 Motorway is a key link into the broader Sydney arterial network and is one of Sydney’s busiest roads. The future M12 Motorway will provide direct access to the new Western Sydney International Airport at Badgerys Creek, connecting this airport to Sydney’s motorway network.
The Project will provide:
- Additional lanes to the M7 Motorway, one in each direction, for around 26km between the M5 Motorway interchange at Prestons and Richmond Road at Oakhurst/Glendenning
- Integration of the M7 into the future M12 through a new M7-M12 interchange; and
- Upgrade to Elizabeth Drive to facilitate a new connection between the eastern end of the new M12 Central Motorway (M12), the M7 and local road network
Tolls for customers on the M7 will not change as a result of this project.
Once completed, the M7-M12 Integration Project will improve the connection into Western Sydney and the new Western Sydney International Airport, saving customers four million hours of time travel per year.
Subject to planning approval, work is expected to start in 2023. Construction is anticipated to take approximately three years and will be complete in 2026.
