ROADS in Cockburn, Fremantle and Melville have featured among those causing motorists the biggest delays in Perth.

Traffic on Canning Highway was rated the worst within those three local government areas when it came to congestion, moving 28 per cent slower than it should, according to Austroads’ Congestion and Reliability Review.

Using data from Google Maps, the report compared the average travel time on a road with that recorded during free-flowing periods to get a “travel time delay” marker.

That method placed the 17km Canning Highway, which links Victoria Park with Fremantle, fourth on the list of most delayed roads in Perth.

East to west roads South Street and Leach Highway slowed traffic by more than 23 per cent each.

The Kwinana Freeway (13th most congested) holds up traffic by 20 per cent, but that figure is considerably higher during peak periods.

In 19th place sits Stock Road, with congestion adding an extra 15 per cent to the average travel time.

Traffic on Armadale Road and Rockingham Road moves 13 per cent slower than it should, while motorists on Cockburn Road are also delayed by 10.5 per cent when compared to times when traffic is free-flowing.

The City of Cockburn is yet to consider the report, which was published in December, but engineering and works director Charles Sullivan said Cockburn Road and Armadale Road had been “major priorities” for some years.

“The upgrade of Armadale Road has now been funded and the design and construction program is being worked up by MRWA, but at this time there is no funding priority on Cockburn Road dualling,” he said.

Reid Highway, in Perth’s northern suburbs, topped the list of congested roads with vehicles moving 33 per cent slower than they should.

Tonkin Highway and Orrong Road rounded out the top three most congested roads.

Both are more than 32 per cent slower than they should be.

Melbourne’s Burke Road, with delays of 80 per cent, finished as the country’s most congested road.

Melbourne finished with three of the top 10 most delayed roads in Australia.

Sydney had seven.
