1) Please don't delete and replace OSM objects, as this loses the editing history.

2) The layer=* tag probably does not mean what you think it does. High Street

3) High Street's pedestrianised areas have signs prohibiting all vehicles (which includes bicycles) and additional signs explicitly and redundantly prohibiting bicycles. It CANNOT be a highway=cycleway. It's a pedestrianised street, which is literally what highway=pedestrian is for (as opposed to mis-tagging pavement/sidewalk areas so that they render on the map). This was explained in the comment I made on your earlier changeset:
