Cwmdare Viaduct  
The photograph and extract from the First Edition Ordnance Survey (1868) map below are of the Dare Valley Viaduct on the Dare and Aman Branch of the Vale of Neath Railway. The viaduct was built to carry the line over the River Dare at a point near the Cwm. The Taff Vale Railway which was laid later also traveled below the viaduct. Constructed by Isambard Kingdom Brunel the timber viaduct was 450 feet in length and 70 feet in height. When the viaduct was dismantled in 1947 it and the Gamlyn Viaduct near Penywaun, were the last of the Brunel viaducts still in existence.
