Bridges & Crossings
Two bridges sit within roughly fifty metres of each other in Billeragh, north County Cork, each crossing a different watercourse and each built to a slightly different design.
That quiet doubling is what makes the spot worth a second look. The older and narrower of the pair spans the Araglin River: an early nineteenth-century road bridge just 3.85 metres wide, oriented on a northwest to southeast axis, with three semicircular arches dressed in sandstone voussoirs. Voussoirs are the wedge-shaped stones cut to form an arch, and the care taken with them here suggests this was not a purely utilitarian piece of work. A string course, a narrow projecting band of masonry, runs along the base of the parapet wall above each arch, and on the upstream face the bridge is fitted with low, stepped, pointed cutwaters, the angled projections designed to divide the current and reduce the force of water pressing against the piers.
The second bridge, known as Coolmoohan road bridge, crosses the Mucknagh Stream about fifty metres to the northwest. It is noticeably wider at 7.55 metres and follows a northeast to southwest alignment, its two arches built in a segmental rather than semicircular form, meaning they describe a shallower curve. The southwestern arch has been repaired at some point, a small visible sign that the bridge has had a working life rather than a purely commemorative one. The two structures together reflect the practical logic of road-making in early nineteenth-century rural Ireland, when engineers had to negotiate a landscape threaded with rivers and smaller streams, often in quick succession, each requiring its own solution.
