Immediately after we built Bruce Bridge back in 2008 we planted the walking surface of this Dry Stone Walling Across Canada bridge with a variety of sedum.
On revisiting the property much later it was obvious the plants were thriving, doing better than I'd expected with all the foot traffic and even mowers driving over it occasionally.
The round fieldstone copes were an experiment. Introducing local glacial granite into the quarried limestone mix created an interesting visual border as well as forming two prominent and very stable 'curbs' for vehicles to pass between.
