I'm going to offer a slightly different opinion - not meaning to wind anybody up and certainly not trolling but:-
a) I know that road quite well and I'm not sure why anyone would cycle it - I don't think I have ever seen a cyclist on it when driving through in the car. In my mind it would be best to ride the quiter residential roads and leave the urban carriageway to the cars & trucks.
b) Taking primary on that road at anything other than the standing starts away from traffic lights is only going to wind up the drivers. It is a nice wide road and there is never a 'door strike zone' as it is a clearway so I don't understand why you would ever want to take primary? unless you are going to accelerate to 30mph at the same rate as any cars around you and even then the likelihood is that you will stop at the next set of traffic lights in a few hundred yards anyway.
Like I said - just a different opinion, interested to see what others think.
