Description

Llandrinio Bridge is a Grade I listed structure featuring three semicircular arches, with the center arch being higher to create a peaked cambered roadway that narrows to a width of 3.75 meters. The arches span 45 meters and have a plain inner ring, followed by a ring of raised and chamfered voussoirs. The piers are designed with triangular cutwaters that rise to a wide band, which continues upward as shallow pilasters. These pilasters are swept into attached ball finials. At the base of the parapet, there is a square band that develops into a cornice over the piers. The parapet consists of three courses with hog-backed coping and bears a roughly inscribed date of 1775 on one of the piers. The ends of the parapets are splayed out to form rectangular terminal piers.

Local climate

Llandrinio Bridge receives an average of 810 mm of rain a year. This makes it drier than 53% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 74% of listed buildings.

It experiences an average of 44 freeze-thaw cycles a year, more than 85% of listed buildings. Of these, 23 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.

Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
