that's the one, southbound was always ok as long as you got over for the lights at the other end (I used to turn right on Southwark Road a bit further)
northbound most certainly need attention focussed, a primary near the end was defo called for and the exit to the left after the bridge proper always looked ludicrous as regards danger, yeah, northbound wasn't good, I used to use the buslane bit rather than have to merge into the single lane for cars, even then you had to be careful when you rejoined the two lanes going towards Liverpool Street as cars turning left would cut across, bad route for bikes without a shadow
