You're quite right, the geometry of that junction could do with simplification.

As the crossing island on East Smithfield is straight across rather than a staggered crossing, a carriageway split isn't really needed here. Having an unmarked crossing here with only a dropped kerb and tactile paving on one side does suggest some of the highway planners have an "interesting" approach to pedestrian safety here!

I'll update it later this afternoon, as there's also a missing HGV weight restriction on Thomas More Street.
