Cadw's description
Location
Crossing the Afon Taf Fechan just N of Pontsarn and some 600m NW of the remains of Morlais Castle.
History
Railway viaduct, built 1866 by Henry Conybeare and Alexander Sutherland for Savin and Ward. The viaduct carried the former Brecon and Merthyr Railway high over the Afon Taff Fechan and was built of limestone from railway cuttings. The viaduct was designed for double-line working but a single track only was installed, on the N side. In deteriorating condition at time of survey.
Exterior
Railway viaduct of 7 arches; abutments, tall slender piers and parapets of coursed irregular sized rock-faced limestone blocks and seven segmental arches with limestone voussoirs . The piers have a projecting impost band and a projecting string course below the parapets. The viaduct is built on a straight line some 138m long and has a maximum height of approximately 28m.
Reason for designation
Included at II* as an historically important and architecturally impressive railway viaduct. Part of the same railway engineering project as the Cefn Coed viaduct (also Grade II*).
