Digby Bridge (and Lock) is a fine stone bridge that forms an imposing feature on the Grand Canal and is one of a group of bridges on the section of that canal that passes through County Kildare. The construction of the arch that has retained its original shape is of technical and engineering merit. The bridge (and sections of canal retaining walls) exhibits good quality stone masonry and fine, crisp joints. The bridge and lock group is of considerable historical and social significance as a reminder of the canal network development in Ireland, which brought about many technical advances and encouraged the development of commercial activity in the late eighteenth century.
