Pont Dyfrdwy (Dyfrydwy) carries a minor road over the River Dee between Cynwyd and Maerdy in north Wales. The substantial four span stone bridge has been strengthened but has changed little visually since the 17th century. Still in use, it is a Grade II* listed building and Scheduled Ancient Monument.
The bridge is said to date from 1612 and is assumed to be the structure recorded by Welsh botanist Edward Lhuyd (1659-1709) at the end of the 17th century. It is similar in style to other nearby bridges across the River Dee, such as Pont Carrog (built 1661) and Pont Cysyllte (1697), which indicates that it too was built during the 17th century.
Pont Dyfrdwy is constructed of random coursed stone. It has four segmental arches of almost equal span (11.9m, 12.0m, 11.8m and 11.8m) with single arch ring voussoirs. The piers feature full-height triangular cutwaters on both sides, forming refuges along the 3.5m wide roadway. The plain parapets are of rubble masonry with large flat stones for copings.
The bridge is 4.6m wide and its deck rises in a hump at the west end but doesn't dip down at the east end because the ground is higher.
On the north side of the bridge is a stepped abutment at the east end and a longer abutment over three low segmental flood arches to the west. East of the flood arches, a stone stair with metal handrail leads down to the river bank. The bridge is 65.5m long overall, and measures 55.1m between abutments.
The parapets may have been partially rebuilt (date unknown). In 1989, the bridge was strengthened without altering its appearance. A stone tablet was erected on the inside of the south parapet wall that reads, "Pont Dyffrdwy, Cynwyd, 1612 built, 1989 strengthened, Clwyd County Council".
The bridge is Grade II* listed and a Scheduled Ancient Monument.
