The monument consists of an imposing stone-built bridge, probably dating to the eighteenth century. It contains four spans with segmental arches, cutwaters on both sides, and plain parapets.

The monument is of national importance as a fine example of eighteenth century road bridge technology and design, and incorporates a number of interesting regional vernacular details such as opposing pedestrian recesses above the cutwaters. Spanning a fast-flowing and often flooded section of the River Dee, the bridge contributes to our knowledge of post-Medieval engineering and bridge building technology. It is one of a group of well-preserved late and early post-Medieval bridges in the middle Dee valley.

The scheduled area comprises the remains described and an area around them within which related evidence may be expected to survive.
