Work is expected to start mid-year.
The project, first spruiked by Deputy Prime Minister Anthony Albanese in August, will widen the southbound section of the Kwinana Freeway between Roe Highway and Armadale Road to accommodate a third lane.
A new on-ramp is also part of the package jointly funded by the State and Federal governments.
It is hoped the upgrade will draw traffic away from Berrigan Drive, a road motorists currently use to bypass the peak-hour log-jam where Roe Highway meets the Kwinana Freeway.
Jandakot residents, however, want more. They remain frustrated at the lack of improved road infrastructure in the area despite continual expansion of the airport precinct.
City of Cockburn engineering and works director Michael Littleton said there were two signalised intersections proposed ” one at the intersection of Berrigan Drive, Jandakot Road and Dean Road and another at the roundabout on Berrigan Drive and Karel Avenue ” and conceptually designed.
Mr Littleton said Jandakot City had also proposed a large roundabout at Berrigan Drive, Jandakot Road and Dean Road.
‘The roundabout and signal options are currently being assessed by the City in consultation with Main Roads WA,’ he said.
‘The intersection at Berrigan Drive, Jandakot Road and Dean Road is critical to the future network structure and the decision on the appropriate treatment for the Berrigan and Karel intersection cannot be made until it is resolved. The City anticipates an outcome in March.’
A Main Roads WA spokesperson said its preference would be for a dual lane roundabout to replace the single lane roundabout at Berrigan and Karel.
Cockburn councillor Steve Portelli told a residents’ meeting last Monday that it might be time to halt development at Jandakot City until local roads were able to accommodate current traffic levels.
