Transport and Industry: Canal Bridge Signs(Talybont on Usk)

In 1865 the canal was taken over by the Monmouthshire Railway and Canal Company which in turn became part of the Great Western Railway. The wording “Heavy Motor Car” referred to motorised commercial vehicles (carriages) and the blank rectangles had lead inserts displaying the maximum weight for that particular bridge. At the base the address for GWR is displayed with each sign supported. by a length of rail.
