Llawhaden Bridge and River Bank Wall

Llawhaden Bridge is a significant structure featuring three main arches, with an additional small arch on the southeast wing for land drainage. The central arch spans approximately 10 meters, while the flanking arches are slightly lower and narrower. The carriageway of the bridge measures 4.5 meters between the parapets. The main arches are constructed from ashlar limestone, showcasing deep voussoirs and projecting keystones. There are cutwaters on the two piers, which include pedestrian refuges. On the north side, a stile provides steps down to the grounds of the old corn mill. Modern protective masonry has been added to the foot of the east pier, which is the only pier fully in the water. The parapet walls have been finished with a flat top, although the coping is made of rubble.

The parapets at both ends extend outwards. On the east side, the parapet merges with the river bank wall, which continues over 100 meters northward. The drainage arch beneath the southern extension of the parapet spans about 2.5 meters.
