Around 72,000 vehicles pass through the intersections at Marmion, Hepburn and Whitfords Avenues in Perth's northern suburbs every day - and they clog up worse than a portaloo at an oyster festival.
To help speed things along Main Roads has been upgrading these congestion hot spots, adding extra (and much longer) turning lanes, better pedestrian and cycle access as well as CCTV systems to improve security and help traffic flow better in peak times.

Transport Minister Rita Saffioti said the upgrades herald the start of the government's plans to improve traffic in Perth's north.
"These intersection upgrades are necessary as an immediate congestion relief measure as the McGowan Labor Government plans its Metronet extension to Yanchep," Ms Saffioti said.
"The new and extended turning lanes have improved traffic flow and safety - especially at peak times."
The City of Joondalup is now completing landscaping works at both intersections.
Any vegetation that was cleared to make way for the widening works was mulched and re-used on site, and old concrete kerbing and pavement was crushed for road base.
