English: Afon Irfon, below the Devil's Staircase, Powys The former drovers' road to Tregaron crosses the Afon Irfon near Llanerch-yrfa three times in four hundred metres. This used to be by means of fords, as marked on most maps. (Does anyone have access to photographs showing how it used to be?). Now, each one has been built up by means of piped culverts under concrete/asphalt - a structure known as an Irish bridge. In times of flood, these are covered, and can be used as fords. Heavy rain fell about 36 hours before this image was taken, and a lot more was forecast as I made my "escape".
