Machine Bridge (also known as Pont y Doctor)

Three segmental arches on piers of coursed hammer-dressed stone with concrete spandrels. On the N (upstream) side are V-shaped stone cutwaters which rise to the height of the imposts, above which they continue in concrete and form brackets supporting the added footway and parapet projecting out from the original bridge. The footway has a parapet comprising a dwarf concrete wall with vertical ribs, and cast iron railings with intermediate and terminal concrete piers. The S side has a similar parapet but has been widened by means of bases extended out from the original piers, from which uprights support the deck. The parapets have terminal piers of rock-faced stone that are integral with added rock-faced abutments.
