Prime Minister Malcolm Turnbull made the announcement during a visit to Perth last week.
He said a tunnel from the Stock Road and Winterfold Road intersection in Hamilton Hill would link up where Stirling Highway meets High Street, near the Fremantle Golf Course.
Rethink the Link co-|convenor Kim Dravnieks questioned the move with stage one – which will link the Kwinana Freeway to Stock Road – yet to be re-approved, and the most difficult stage, a link from the tunnel exit in Fremantle over the Swan River to the port, still yet to be mapped out.
“How can Canberra fund something they have no designs for through North Fremantle?” Ms Dravnieks said.
The cities of Cockburn and Fremantle were quick to condemn extra funding for the $1.9 billion project, both arguing the PFL was not a long-term solution for traffic congestion and freight movement issues. The Greens, along with State and Federal Labor, also spoke against the announcement.
But there was support from the City of Melville, with Melville Mayor Russell Aubrey welcoming the announcement.
He said the decision showed “the State Government’s determination to avoid impacting residents in the City of Melville, especially those in Palmyra”.
WA Chamber of Commerce and Industry chief executive Deidre Willmott said the PFL would make accessing the Fremantle port easier, while construction would create employment opportunities.
