Construction on the METRONET Thornlie-Cockburn Link is ramping up with preparations underway for the Mandurah Line shutdown, between Aubin Grove to Elizabeth Quay, from December 26.
Some minor changes along the Kwinana Freeway southbound between Berrigan Drive and Armadale Road are also required to facilitate the shutdown.
From September 27, 2021 to early 2022, speeds will be reduced and some traffic will be shifted to a new road built alongside the freeway, to allow for works in the rail reserve.
The Berrigan Drive entry ramp to the freeway will also remain closed. Drivers should proceed with caution and adhere to the posted speed limits and directional signage in place.
The Mandurah Line will close from Aubin Grove to Elizabeth Quay stations from December 26, 2021 for a minimum of 20 days.
The shutdown is required to shift the Mandurah Line tracks further apart to enable the new Thornlie-Cockburn Link tracks to be built in between them.
In June, Transperth conducted a survey of 4,500 Mandurah Line passengers to understand what travel changes commuters may make during the shutdown. This feedback is helping shape public transport replacement services, with detailed information to be released in November.
The Thornlie-Cockburn Link will be Perth's first east-west cross line connection, linking the Mandurah and Armadale lines and making travel through the south-eastern suburbs quicker.
The McGowan Government has 15 METRONET projects completed, under construction, planned or in procurement.
As stated by Transport Minister Rita Saffioti:
"We know the Mandurah Line shutdown and some changes to the Kwinana Freeway will be inconvenient for many people and we apologise for this in advance.
"The changes to the Kwinana Freeway southbound include the speed limits being reduced between Berrigan Drive and Armadale Road, along with some lane changes.
"We want to give people as much notice as possible so they can plan ahead and be prepared for disruptions.
"We have conducted a passenger survey and are talking to affected stakeholders, including Fiona Stanley Hospital, to gather their feedback to inform train replacement service planning.
"The AFL Grand Final coming up this weekend highlights just how important the METRONET Thornlie-Cockburn Link project is, providing residents in the south-west corridor a direct link to the stadium.
"Thank you to all commuters for their patience while we build the infrastructure for tomorrow."
