Residents have until next Friday to submit comments to Main Roads on the plan.
The State and Federal Governments recently committed funding to start building the section of the major arterial road.
The Federal Government allocated $400 million towards the $800 million first stage of the project.
At a Swan Chamber of Commerce meeting last week, City of Swan CEO Mike Foley said the State Government had committed $196 million to build the section of the highway from Gnangara Road to Muchea.
‘There’s a high percentage of heavy haulage on Great Northern Highway ” about 17.5 per cent of the traffic is trucks and road trains,’ he said.
‘If the Perth Darwin Highway stops there (Gnangara Road), the trucks will all end up on Gnangara Road. We haven’t been told how that will be managed.’
The PDNH planning study includes environmental assessments, Aboriginal and European heritage assessments, concept design, drainage investigations and consultation with landowners, key stakeholders and the community.
The planning design concept provides for a four-lane freeway standard road with a nominal 100m wide reservation, a rapid transit route in the freeway central median and local access via interchanges.
Main Roads, Department of Planning, Department of Transport, Department of Environment and Conservation, Department of Water, Water Corporation, City of Swan and Wanneroo and Public Transport Authority have met three times to discuss the study, and agreed on the freeway concept.
Residents can provide comment on the freeway concept plan to Carolyn Walker at email@example.com or PO Box 178 Como 6952.
