A typically well-built canal bridge, which is a valuable part of the extensive canal-related built and industrial heritage of County Longford. Although humble in form, this structure has a simple and functional elegance. It is robustly built in good-quality 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 between Coolnahay to Cloondara, which started in 1814 and was completed in 1817 (28 years after the canal work was started in Dublin. The main contractors involved were Henry, Mullins and McMahon. Although the canal is currently disused, the towpath provides a recreational amenity and this bridge affords interesting views to the pedestrian as well as being a notable feature and landmark in the landscape. Visible from the nearby road, it brings architectural and historical interest to the Lyneen area to the southeast of Killashee.
