This bridge is just to the north-east of Aberbran-fach farm, approximately 4.5km west of Brecon. It is a small, single span, stone-built humpbacked pack horse bridge. Its parapets have been removed and its overall width is 2.5m (1.8m at the crown) and its 9.75m span crosses the Nant Fran. The cobbled roadway rises steeply and is used by pedestrians or tractors. The bridge probably dates from the 18th century.
