The final piece of Western Sydney International Airport’s (WSI) road network is now in place with the opening of a junction between the M7 and M12 motorways.
Opened on Sunday, the $312 million interchange at Cecil Hills will allow “seamless connections” from the Westlink M7 motorway onto the new M12, which serves WSI and the Bradfield “aerotropolis”. It comes after the majority of the M12 opened in March.

“In recent weeks, Western Sydney residents have already started experiencing the benefits of this work, with over 50 kilometres of combined new lanes opened along the M7,” said NSW Roads Minister Jenny Aitchison.
“With the M12 toll-free motorway and now the connection to the M7 open, Western Sydney is gaining the modern road network it needs to support its growing community and prepare for the opening of the new international airport.”
According to the NSW Government, the construction saw bridge segments built in stages and pushed into position over the M7.
“This innovative approach minimised disruption to the community and environment while keeping motorists moving on the Westlink M7 Motorway during construction,” the government said.
“The M7 widening has expanded the motorway to three lanes in each direction between Richmond Road and the M5 Motorway to reduce congestion, improve travel reliability and provide a stronger freight link across the region.
“Motorists travelling southbound from Marsden Park to Liverpool are expected to save up to 13 minutes in travel time.”
Federal MP for Werriwa Anne Stanley has also welcomed the opening of the new interchange, which includes seven new bridges and additional lanes.
“The Albanese Government is proud to have worked with the NSW Government to deliver the incredible new M12 motorway, between Cecil Hills and the new Western Sydney International Airport,” she said.
“Now, the interchange between the M12 and the M7 – the final piece of the puzzle – has been delivered by the NSW Government.
“I’m so pleased everyone will be able to make the most of seamless journeys across the motorway network, to catch their flight or head into work at the new airport.”
WSI is set to open for freight traffic next month, with Jetstar to operate the inaugural commercial passenger flight on 25 October. Another milestone for the airport’s transport network was reached this month with the final tracks laid for its metro line.
