The inscription reads "G IV R Aldworth Bridge Richard Griffith Engineer 1826", though the final digit is not entirely legible and may be a five. That the bridge bears a name at all is unusual enough; that the name attached to it belongs to one of the most consequential figures in nineteenth-century Irish surveying and geology makes it quietly remarkable.

Richard Griffith is best known today for Griffith's Valuation, the comprehensive land survey completed in the 1860s that became an indispensable tool for tracing Irish ancestry after the destruction of so many census records. But decades before that project, Griffith was already active as a civil engineer and geological surveyor, and the Aldworth Bridge appears to date from that earlier phase of his career. The "G IV R" inscription places it firmly in the reign of George IV, who ruled from 1820 to 1830, consistent with the 1825 or 1826 date on the plaque. The bridge itself is built in coursed ashlar limestone, meaning the stone is cut and laid in regular horizontal courses, giving a clean, dressed appearance. Its wide elliptical arch spans roughly eight to ten metres across the Dalua, with a projecting course framing the arch ring and a linear band course running above it. Thick piered abutments anchor each end of the parapet wall, topped with an overhanging limestone coping. It is a competent and considered piece of early nineteenth-century civil engineering, proportioned to carry road traffic across a river that could not simply be forded reliably year-round.

The Aldworth name likely refers to the Aldworth family, prominent landowners in north Cork, though the notes do not confirm the connection directly. What the plaque does confirm is that this crossing was a deliberate infrastructural investment, engineered and commemorated at a time when improving roads and river crossings was bound up with broader ambitions for the region's economy and administration.
