@kaputnik: same when I went through yesterday and today. Might not just be down to school holidays though - I suspect that it's when bacon roll loading blocks the inside lane and all eastbound traffic stops until the right turn light changes. The current lane closures means this isn't happening. Close Russell Rd and the problem would disappear (or at least start to disperse elsewhere). West Coates is remarkably quiet. Queues westbound are rarely long in any event - maybe half a dozen vehicles at most, even at peaktime.
But without all the lanes where would the bacon roll loading take place?
Also, my current favourite rubbish parking is by the solicitors (Clancy something or other) who most days park their mini outside the office during Greenway hours, facing the wrong direction.
