Appraisal

A typically well-built canal bridge, which is a valuable part of the architectural and industrial heritage of County Longford. Although humble in form, this structure has a simple and functional elegance. It is robustly built in fine stone masonry, which is testament to the long-term ambitions of the Royal Canal Company at the start of the nineteenth century. It was probably built to designs by John Killaly (1766 - 1832), the engineer responsible for the construction of the Royal Canal through County Longford. The fine construction of Coolnahinch Bridge and the associated canal structures on the site, including a lock keeper's house (13313001) and lock (13313003), are an important reminder of the confidence the canal building era prior to the demise of this transport system in the mid-to-late nineteenth century.
