I. K. Brunel Viaduct at Aberdare, South Wales

A Youtube video shows this masonry and timber viaduct being dismantled. There remains the abutment and several piers; this and the nearby Gamlyn Viaduct at Penywaun were the last to be decommissioned and were among the longest in Wales. Since the River Dare Viaduct is in the Dare Valley Country Park an information plate would not go amiss.
