I just found this out today by cycling it. You can now shoot straight through the section at Surrey Quays/Southwark Park making this route extremely quick and largely safe.
I don’t like the crossover at Surrey Quays station OR that weird side road dip just before the McDonalds but all things considered this is a great route.
Apologies if this is off topic, I CBA to make London cycling
I’d join if so. I commute on a folding bicycle in London, and quite like the discussion topic.
