What makes it unusual is the combination of materials: the main fabric is random-rubble sandstone, the kind of rough, uncoursed stonework that was practical and locally available, but the builder finished the arches with dressed limestone voussoirs, the precisely cut wedge-shaped stones that lock an arch together and give it its characteristic strength. That pairing of workaday rubble with more refined limestone detail suggests a structure built with some care and a modest budget for quality where it mattered most.

The bridge spans the Clyda River on an east-west axis and measures 7.4 metres in width, accommodating a road of reasonable ambition for its era. Its six semicircular arches each span roughly three metres, and the piers between them are slender at about one metre wide. On the upstream face, the piers are fitted with low pointed cutwaters, the angled projections designed to divide the current and reduce the force of water pressing against the structure during flood. The parapet walls are finished with vertical stone coping along their tops. Taken together, these features point to a construction date somewhere in the late eighteenth or very early nineteenth century, a period when Cork's road network was being improved and formalised under grand jury investment, and when vernacular bridge-building had developed reliable conventions of this kind.
