Built by the Vale of Neath Railway whose broad-gauge line to Merthyr was begun in 1847 and opended in November 1854. The engineer was the renowned I K Brunel of London and the main contractors were Hunt, Humphries & Edwards. Merthyr Road bridge was built to accommodate a single line of broad gauge track (7 foot width) which ran from Gelli Tarw Junction to Merthyr Tunnel. Delays in opening were caused by the construction of the Merthyr Tunnel (to SE of Llwydcoed) and the diversion of the company''''s efforts to the Aberdare line where the coal trade had expanded dramatically. In the mid 1860''''s, the Vale of Neath Railway was absorbed into the Great Western Railway and by 1872 the line was converted to standard gauge. The line was nationalised in 1948 and subsequently closed in 1962.


Single-arch over-bridge of wide elliptical proportions (to accommodate Brunel''''s broad gauge track). Coursed hammer-dressed masonry with droved margins to voussoirs and tall plinth courses. Coursed masonry to arch soffit. Broad string-course at road level links to cappings of ramped and splayed abutments which flank the track-bed. Parapets with blocked cappings and twin stone piers to pedestrian entrance and ramp leading down to former platform at NW side of bridge. Modern tubular bridge for pedestrians (by Saunders Tubecrafts of Liverpool) is attached to E side of roadway.
