Built to carry Bailey's Tramroad across Cwm Llanwenarth. This tramroad was built by Crawshay Bailey and was opened in 1821 from Nantyglo Ironworks to the Brecknock and Abergavenny Canal at Govilon. The line of the tramroad at this point followed a loop along the contour of the valley. It was superseded when the Merthyr, Tredegar and Abergavenny Branch line opened in 1862.


Substantial single-arched tramroad bridge built of local coursed rubble. The semicircular arch has dressed stone voussoirs and the parapets are swept out at either end. Now overgrown.
