Though the arch is not dry laid I rather like this bridge at Fox Harbour, Nova Scotia
Under the bridge the concrete looks to have been poured onto flexible plastic culvert pipes, all cut in half and joined together to form a kind of elliptical arch. The stonework on the abutment looks to be all dry laid. In any case the ivy makes everything look good. Except of course if you live in Ireland and it's taking over and you'd rather not see it.
