Cut-stone triangular cut-waters. Cut-stone coping to parapet walls. Three segmental arches. Cut-stone voussoirs. Rubble stone soffits with render over.

William Bridge is a fine rubble stone bridge that forms an attractive feature on the Lyreen River and is one of a group of bridges on the section of that river that passes through County Kildare. The construction of the arches that have retained their original shape is of technical and engineering merit. The bridge exhibits good quality stone masonry and fine, crisp joints, most notably to the cut-stone triangular cut-waters. The bridge is of considerable historical and social significance as a reminder of the road network development in Ireland in the late eighteenth century.
