TfL has been interested in keeping traffic flowing since long before Boris became the Mayor.

A lot of people are surprised by the legality of the right turn from the left lane outside the station - it's definitely not what you would expect given the road layout, but as rshdunlop says above (and has said before elsewhere on the forum) it's clearly marked as legal on the road and the signs before the bend.

What I've noticed is that having both lanes about to make that right turn and then immediately have to filter into one lane does cause a bit of jockeying.

I look forward to any constructive proposals to improve the whole layout, but short of expensive major work to build a bridge or a tunnel, I don't feel very optimistic of significant improvement. I would definitely support having a single continuous crossing outside the station, though.
