Set into the western parapet at ground level, a limestone slab measuring just over a metre wide commemorates an act of civic infrastructure from 1635, the kind of record that more often survives in paper archives than carved in stone on a roadside.

The inscription, cut in low relief capital letters, reads in translation: "Peter Creagh, son of Andrew Creagh, Mayor of Limerick, had this bridge and street made at the expense of the city of Limerick, the year of the Lord 1635." The bridge sits roughly 1.5 kilometres north of Limerick City, carrying a route over a stream that flows westward to eastward into the River Shannon. That it falls technically within County Clare rather than Limerick adds a small geographical wrinkle to its civic identity, since the man who commissioned it was mayor of a city on the opposite bank. Peter Creagh, son of Andrew Creagh, was spending municipal money on infrastructure that extended the city's reach beyond its own county boundary, which suggests the crossing served a route of genuine practical importance rather than a purely local need.

The slab itself is the detail worth looking for. It sits at ground level on the western parapet, not elevated or ceremonially placed, which means it is easy to walk past without noticing. The Latin formula follows a conventions common to early modern civic monuments across Europe, where the commissioner, his lineage, the nature of the work, and the funding source are all recorded as a matter of public record. That this particular example has survived intact into the present, still legible and still in situ on a working bridge, is the quiet peculiarity of the place.
