Description
This structure is Bridge 105 over the Brecknock & Abergavenny Canal, built from rubble sandstone. It features a semi-elliptical arch made of stone voussoirs and has a projecting keystone. The bridge has a humped parapet that flares out to square piers, topped with slab copings. On the east side of the bridge, there is a tall iron lozenge-shaped sign erected by the Great Western Railway Company to restrict 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). Great Western Railway Ltd. Paddington Station. London.”
