Bridge 107 over the Brecknock & Abergavenny Canal including Iron Sign

This is a bridge built over the Brecknock and Abergavenny Canal, constructed from rubble sandstone. It features a semi-elliptical arch made with stone voussoirs. The bridge has a humped parapet that extends out to square piers, topped with cemented copings. To the south-east, there is a long retaining wall for a footpath, which includes a vertical stone-slab stile, although the slab is missing near the end.

At the north-east corner of the bridge stands a tall iron sign in a lozenge shape, erected by the Great Western Railway Company to limit heavy loads. The sign states: "Motor Car Act 1886 and 1903. Notice this bridge is insufficient to carry a heavy motor car the registered axle weight of any axle which exceeds (blank) tons or the registered axle weight of the several axles of which exceed in the aggregate (blank) tons or a heavy motor car drawing a trailer if the registered axle weight of the several axles of the heavy motor car and the axle weights of the several axles of the trailer exceed in the aggregate (blank).
