History

Part of Berecon and Merthyr Railway constructed 1860s, the line substantially supported by Brecon bankers and the de Winton family of industrialists with the aim of transporting coal and iron from the industrial valleys. First section between Brecon and Pant near Dowlais opened 1863, later extended to Dowlais; branch line to Merthyr from Ponsticill Junction followed Taf Fechan River and was opened 1868. Engineer for Brecon to Pant section was Henry Conybeare and for Pontsticill to Merthyr Alexander Sutherland. The engineering achievement of this line is described by Barrie as "the famous Seven Mile Bank, constructed throughout on a shelf cut into the hillside and falling towards the Usk for the first half-mile at 1 in 68 and then for 61/2 miles at 1 in 38 so that southbound trains have to overcome a rise of 925 feet in seven miles". Closed 1960s. This bridge was built to take the railway over an existing trackway, possibly associated with Abercriban quarries to E. Valley below flooded by Pontsticill Reservoir in 1920s.
