In the 2011 census, 90.1 per cent of dwellings in South Perth had at least one motor vehicle, just below the WA average of 91.1 per cent.
Although the City of South Perth said they had not noticed much of a change in traffic, they said the freeway entry point remained an area of congestion.
‘The City has concerns that congestion in this area will increase with the closure of Riverside Drive,’ Mayor Sue Doherty said.
‘With no northbound ramp to the Kwinana Freeway at Canning Highway additional traffic is being directed through the City.
‘Similarly, no southbound on-ramp at Manning road contributes to traffic congestion on Canning Bridge which could be avoided.’
In recent years, the City of South Perth and South Perth MLA John McGrath had been urging the State Government to fund a Kwinana Freeway southbound Manning Road on-ramp.
During the 2013 election, Mr McGrath told the Gazette he was disappointed the Manning Road on-ramp was not included in the transport budget for 2012-13.
He said he was concerned that unprecedented population growth had seen a rapid increase in vehicle numbers, which was having an impact on traffic.
Ms Doherty added the entry to the freeway along Labouchere and Mill Point Roads can be ‘slow and bank up’ during the morning peak hours with queue lengths sometimes extending beyond the intersections.
A Main Roads spokesman said there have been no reports or evidence that shows any recent increase in travel times or unusual traffic congestion on the section of the Kwinana Freeway between Mill Point and Mounts Bay Roads.
