CONSTRUCTION on the Thornlie-Cockburn Link and Yanchep Rail Extension is on track to begin next year, with the project definition plans for the METRONET projects approved by Cabinet and to be submitted to Infrastructure Australia in coming weeks.
The Yanchep Rail Extension will deliver the last 14.5-kilometre section of the Joondalup Line from Butler to Yanchep and help to support ongoing growth in the area and reduce road congestion.
The 17.5-kilometre Thornlie-Cockburn Link will connect the Mandurah and Armadale Lines, creating development opportunities around the proposed Nicholson Road and Ranford Road stations and improving access from the southern suburbs to Optus Stadium.
Thornlie Station will become a through station and a new platform will be built at the northern end of Cockburn Central Station. An additional three kilometres of rail line will be constructed to duplicate the section between Beckenham and Thornlie Stations.
The projects, with a current combined budget of $1.056 billion, are being delivered by the State and Commonwealth governments through a joint funding arrangement, with the Commonwealth funding $700 million and the WA Government $356 million.
The completion of the project definition plans confirms positive benefit cost ratios for each project, which will meet the precondition for the Commonwealth Government's funding, which was subject to positive business cases.
A tender seeking consultants to carry out geotechnical and groundwater investigations for both METRONET projects has already been released and will inform further detailed design for the railways.
Transport Minister Rita Saffioti said the station designs will be the first examples of the new METRONET approach to integrated transport and land use planning, while being flexible enough to change as development around the station occurs in the future.
"We have developed plans to ensure this investment creates places where people can live the lifestyle they choose and still have the option to access jobs, schools, the CBD and other facilities like the airport and Stadium," Ms Saffioti said.
