The road bridge over the Dungourney River in Midleton, County Cork, is the kind of structure that most people cross without pausing, yet its stonework repays a second look. Built from ashlar limestone, a technique in which stone is cut and dressed into precise, smooth-faced blocks, it carries a single segmental arch, meaning the curve is shallower than a semicircle, a form that suited the practical demands of road traffic rather than the grander ambitions of decorative engineering. What gives it particular character are the rusticated voussoirs, the wedge-shaped stones that line the arch, which have been left with a deliberately roughened or projecting face. That contrast between the clean ashlar of the main structure and the textured arch stones is a small but deliberate piece of craftsmanship, the kind of detail that suggests a builder who knew exactly what effect he was after.
