Carmarthenshire Dock tramroad bridge

A well constructed single-arched stone bridge, believed to date from 1805. Long abutments are straight on its northern side but curved outwards slightly at its south-eastern wing. They are battered on the upstream side. There is a shallow segmental arch, now of red brick. The bridge itself is of carefully dressed sandstone. On the north elevation, the arch is inset to seat weir planks to dam the river, probably to assist scouring of the dock. Large copings are level with the bridge deck, which is typical of early nineteenth-century tramroad bridges in being flat and without parapets. Unusual iron stansions bolted to the copings support modern railings.
