Built 1809-11 to carry the Llam-march tramroad, begun in 1794 by John Dadford, engineer. This section of tramroad was built to link the Brecknock and Abergavenny Canal at Gilwern to the collieries and iron-ore quarries at Llam-march, via the Clydach Ironworks, which was set up c. 1793 by Edward and John Kendall, who sub-let the works to Edward Frere and Thomas Cooke. The Brecknock and Abergavenny Canal Company resolved to allow Frere, Cooke and Edward Kendall to build a railroad on 28th May 1794 from Llam-march to the ironworks, the iron company paying a rental of 8% a year of the cost of construction and to be responsible for all repairs. By June 1795, the railroad was largely complete. In 1800, the Brecon and Abergavenny Canal was completed from Brecon to Gilwern, and by 1812, the canal was extended to link with the Monmouthshire Canal at Pontymoile, which enabled direct links with Newport and the Bristol Channel . With the expansion of the canal system, the Clydach Iron Company successfully applied in 1809 to extend the Llam-march tramroad to the canal at Gilwern, where they built a wharf and warehouse; this section of tramroad was completed in 1811. In 1960-62, the Abergavenny -Brynmawr section of the Heads of the Valleys Road was built (engineers Rendall, Palmer and Tritton), involving the provision of a new bridge over the Clydach and a new junction to Station Road, rendering the old tramroad bridge redundant


Rubble construction. Single segmental arch of impressive span with ashlar voussoirs. Parapets removed and replaced with C20 fence.
