Three spans of granite slab laid across piers of dry stone, no mortar anywhere in the structure. The slabs are said to weigh around eight tonnes each, and nobody is certain how they were moved or precisely when.
Visited twice this year. In August it was full of tourists and in February there was nobody at all and the river was loud enough to drown conversation.
Narrow enough that two people cannot pass without one of them stepping into a recess cut into the parapet. These recesses are the detail I look for now — they date a bridge more reliably than anything written on the plaque.
The path on the far side has been rerouted twice since the flood, and the old line is still visible as a slight depression in the grass.
For two years I recorded span widths with a tape and no witness, and the numbers drifted by up to forty centimetres on repeat visits. Now everything is photographed with a staff in frame and measured afterwards from the image.
The earlier records stay in the file, marked unreliable. Deleting them would hide the mistake rather than correct it.
