Tow path to the west side with dressed limestone kerbing. Located to the northeast of Killashee.


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 this part of the Royal Canal. This bridge forms part of a group of canal structures to the northeast of Killashee, along with the lock (13311007) and the associated lock keeper’s house (13311005) and is an integral element of the built heritage of County Longford.
