I think close off those entrances at Washington Galleries when they implode Chariot House as it's next to the road in which Buses use coming in/out of the galleries, plus there would be some debris on the road and dust also, unless they due it during the night or on a Sunday when it's less busy.

They've already dug little square holes on the Car Park to put explosives into I think. No doubt there will be an infestation of rats in there also, as I seen a few go into nearby bushes a few weeks back.

Either way it'll brought to it knees in the next few weeks
