Pont Sarn-Ddu (also known as 'Roman Bridge')

Clapper bridge of 8 spans, approximately 18m long with long parapetted approaches of similar length, rising slightly at the bridge ends. Rectangular rubble piers, rounded upstream as cutwaters; massive lintels of slatestone. Downstream the piers have slatestone projections on their N and S (inner) faces, half way up, which possibly relate to timber supporting struts in the original construction. The two northern-most piers and their abutments appear to have been rebuilt. Above, modern concrete kerbs and low slatestone copings for steel balustrade; simple datestone to this of 1955. The rubble approach parapets have roughly-dressed slate-slab copings and are splayed slightly at the S end.
