Expected to open in 2026, the M7-M12 Integration Project will provide new lanes to increase road capacity, reduce congestion and improve travel times for motorists and freight around Western Sydney. The project is supporting the growth of Western Sydney by widening a 26-kilometre stretch of the M7 Motorway and delivering a seamless connection to the 16-kilometre M12 Motorway. This integration will eventually provide direct access to the coming Western Sydney International Airport (expected to open in 2026). The M7-M12 Integration Project has progressed significantly since construction began in August 2023. Safety barriers have been installed along the M7 Motorway, earthworks are underway, and work has begun on building the foundations of the main bridges that will connect the M7 to the M12. This vital new Western Sydney infrastructure is expected to deliver significant benefits for drivers, businesses and communities. Once complete, the new motorway and bridges will alleviate congestion along one of the busiest road transport corridors, the M7 Motorway, which currently accommodates an average of 195,000 trips daily. The project is anticipated to support around 1,600 jobs at the peak of construction, contributing to both local employment and regional economic growth.
WestConnex connects Sydney’s west and southwest suburbs with the city centre, airport and Port Botany via a 33-kilometre traffic-light-free motorway. Following more than four years of construction, the final stage of WestConnex, Rozelle Interchange, opened to traffic in November 2023. Delivered by the NSW Government, the interchange is now operated and maintained by WestConnex and is under a concession agreement until 2060. While there were some initial congestion challenges on the surrounding road network following opening, WestConnex’s Rozelle Interchange has delivered substantial time savings for motorists travelling from Western Sydney. For example, a journey from Parramatta to the city is now 15 minutes quicker, a reduction in travel time of over 30%; and a trip from Liverpool to the city now takes approximately 40 minutes, a 10-minute saving. 2 While some congestion was experienced in the surrounding areas of the Rozelle Interchange after opening, travel times on key surface routes have improved in recent months following the initial settling period post opening. The upcoming opening of the Sydney Gateway, being delivered by the NSW Government, will provide a new, toll-free connection from WestConnex, further improving journey times to Sydney Airport, the M5 East and M8. 1 T he final piece of WestConnex delivered by Transurban, M4-M8 link, opened in January 2023.

Individual travel times, alternative trips and travel savings may vary based on specific origin, destination and traffic conditions at the time of travel
