The City of Swan wants the State Government to build a multimillion-dollar overpass to improve traffic flow at Perth's worst congestion hotspot.
In a recent survey of more than 4000 motorists, congestion at the intersection of Malaga Drive and Reid Highway was considered to be the city's worst.
Short turning lanes, inefficient traffic lights and many trucks were blamed for the regular delays, long queues and gridlocked traffic at the Noranda intersection.
The Government has allocated $2.1 million for improvements to the intersection - including upgraded traffic signals, longer right and left-turn lanes and new road signs.
But Swan mayor Charlie Zannino said these plans were "a temporary fix that would not alleviate the delays in the long term". He said the $2.1 million would be better spent on design work for an interchange overpass.
