Railway viaduct SW of Aberdulas Farm (partly in Llangammarch Community)

A skewed 3-bay viaduct with snecked rock-faced shale piers and abutments, iron girders and brick parapet. The piers have wider bases with pointed cutwaters and are extended out on the S side to accommodate an extension of the piers for a second track. The abutments are likewise extended on the S side, beyond which they curve outwards and downwards and have rock-faced copings (brick to the NW side). The piers have freestone caps below the deck. The deck is constructed of girders and narrow brick jack arches. The parapets have shallow terminal and intermediate piers with brick copings, the terminal piers having coarse concrete saddleback copings.
