Description
This is a single-carriageway road bridge located over Cwm Trafle, southeast of Tycwtta Farm. It is constructed from coursed rubble stone and features a single segmental arch made of hammer-dressed voussoirs and a keystone, which is set back from the main face of the bridge behind hammer-dressed quoins. Above the arch, there is a thin dressed stone band at the base of the parapet. The parapet itself is stepped inward, curves outward at the ends to form simple square terminal piers, and is topped with flat stone copings. On the upstream side of the parapet, there is a stone tablet that commemorates the construction of the bridge.
