Hi, 
Thanks for coming back to me on this. This is a really convoluted intersection so I hope my earlier message didn't sound harsh.

A couple of caveats; I'm not sure if OSM has best practice guidelines around displaying turning lanes? Or if a 'link' road should only be used when there is physical separation of roadways? (ie. a traffic island)

My original comment was referring to how best to display traffic flow through the intersection; for instance traffic travelling south-west from Springvale Rd turning on to Centre Rd pass through the intersection before a 'dog leg' right onto the secondary link toward Centre Rd. Comparing this to aerial imagery I wonder if it would be better having this secondary link begin to the north of the intersection (after the traffic signal?) and pass across the intersection, to show these lanes deviating away from Springvale Rd?
My comment would be the same for traffic travelling north-west from the Princes Hwy turning on to Springvale Rd too.

Keen to hear your thoughts, thanks!
