I decided to try for myself, and the results are below in a little annotated video
One has to remember that the road above is simply an access road to the centre, and is brand new. The facilities aren't dictated by existing road structures, or drains, or through traffic. The cycle facilities here are as they were designed. Which is slightly worrying; one might assume it is all done for a bet.
As a pedestrian things aren't exactly rosy either. This pavement is hardly generous for walkers, and, further round, the gyratory pedestrian crossing doesn't seem to have been upgraded at all. People waiting to cross are being pushed into the road by the sheer weight of the crowds, into a multi-lane road where car speeds are way in excess of the 30mph limit.
The powers that be are seemingly intent on re-creating the 1980's Birmingham Bull Ring in East London. Except with somewhat less charm. And congratulations to them - I really think they are succeeding.
