Please provide the link to substantiate your claim.
As to your
" what roads are going to be used for the increased traffic "
Unlike Fremantle where there is only one way in or out or of the port facilities, you can take your pick, Thomas road to the free way ( two sets of traffic lights from memory ), Anketell road to the free way ( no traffic lights ) Hope valley road ( which dissects the railway line ), no traffic lights to the freeway ( no lights but two roundabouts ).
By the way, I'm not looking forward to the release of the report on the new kids hospital, built on cols watch, what a debacle.
