Rondetto, wrong on so many counts!
a) Henblas St from Chester St has been no entry like since……. forever.
b) Henblas St has been one way from by the sports shop as long as I can remember.
c) The ‘Pedestrians only’ sign I think you refer to is a temporary one on an adjacent street (Lambpit St) probably placed there because of the Monday market.
As far as disabled access/ parking is concerned, they do have the right to park at certain times but that facility is abused beyond measure.
Not entirely sure what the whole point of your post is.
