Late C18 canal bridge on the Monmouthshire Canal which was a prime factor in the industrial development of the Gwent Valleys. Built by Thomas Dadford Junior, 1792-9, the canal ran between Newport and Pontnewynydd, with a branch between Crindau and Crumlin. Tredegar Lock is the N most of the Llantarnam flight of three locks S of Cwmbran.


Slightly hump-backed canal bridge, built into canal lock to N. Rubblestone with single segmental arch of dressed sandstone voussoirs and horizontal parapets with flat coping. Abutments splay outwards on each side to square piers, those on the W side in a deteriorating condition.
