Llangynidr Bridge lies in the Hundred (county division) of Crickhowell and is similar in style to the Crickhowell Bridge over the Usk, which dates from 1706. It has six arches, which vary in span from 22 to 30 feet, divided by v-shaped cutwaters topped by pedestrian refuges and parapets with plain coping stones. The cutwaters continue up to the parapet, in order to provide spaces for pedestrians to stand to avoid wheeled traffic crossing the bridge. It is 69 m (230 ft) long and the road is 2.4 m (8 ft) wide. It is considered a particularly impressive example because of its height - reducing the danger of flooding - and its location, which gives a good view of the architecture.
