"When Lady Rusell, not long afterwards, was entering Bath on a wet afternoon, and driving through the long course of streets from the Old Bridge to Camden Place, amidst the dash of other carriages..." (157). The Broadview edition of Persuasion describes the Old Bridge's location: "[The Old Bridge] crossed the Avon at the south side of the city. Lady Rusell's carriage would have had to travel through the centre of the city on it way to Camden-place" (157).
