Well done Pete (and Grandarog). Yes, it's hearses that will drive slowly over that bridge. There's a circular 'dropping off' point just after the bridge for that area of the cemetery. The bridge further along looks like it's for pedestrian use only. It's now part of the North Downs Way walking route on the way to Canterbury and beyond. The cemetery is massive and is on both sides of Old Charlton Road. I found it quite fascinating.
So, over to you Pete and commiserations Grandarog.
