Early C19 road bridge, built in 1827 to the designs and under the supervision of the county architect for Denbighshire, Thomas Penson (Jnr). The bridge was part of a scheme to build a new road between Llansannan and Henllan and spans the boundary of both parishes. Built by Robert Andrew, stone mason, at a cost of £250-0-0 and using local stone quarried limestone from Henllan and Llwynderw.  

Tall limestone road bridge with short single span culvert at the base. Built of hammerfaced limestone laid to courses; slab dripcourse and parapet capping. The walls of the bridge curve outwards to either side of the culvert at the base of the narrow river valley. The culvert is a single span arch of roughly dressed stone voussoirs with stressed keystone and dripcourse. Flanking the arch are tall tapering buttresses which reach to the dripcourse at the base of the parapet, and the buttresses are echoed by a sloping projecting bay at the extreme end of both sides.  

The arched roof of the culvert arch is lined with brick.  

Listed as an unusual example of an early C19 road bridge.
