This section of the Montgomeryshire canal (the western branch) was constructed between 1815 and 1821 under the direction of the engineer, Josias Jessop. The bridge was built to carry a driveway to Glanhafren House and the iron beams of the bridge were cast in 1889. As the house is early C19, there may have been an earlier bridge on the site.


The bridge is carried on flat iron beams. The following inscription is cast into their exterior faces: Glanhafren Bridge 143 1889. The parapets are of blue brick with recessed panels and chamfered stone copings. There is a pier at each end and in the centre, all with saddleback copings. Between the piers are iron railings with ball finials. They form open square panels containing circles. To the W (road side) the parapet walls splay outwards and continue for a further 2 bays. The flat iron beams are supported on splayed brick abutments with stone copings which could be earlier features.

Reasons for Listing

Listed as a decorative element of the later works associated with the Montgomeryshire Canal which carried the driveway to a house of some architectural pretensions. It is the only bridge of its kind over the canal.
