Cadw's description

Crossing the Ogmore river approximately 1km NE of Merthyr Mawr church.

Built in 1827 (date on bridge) by Morgan Thomas of Laleston, for Sir John Nicholl of Merthyr Mawr Estate. Nicholl had purchased the Merthyr Mawr Estate in 1804 and built a new mansion for himself, for which he appropriated the original road to Merthyr Mawr village as his private drive. A new road was therefore adopted, requiring a new bridge across the River Ogmore. The present bridge replaced an earlier bridge with a wooden deck on stone piers which had been erected early C19.

Single-carriageway road bridge of coursed, hammer-dressed stone, ramped to centre. Abutments are wider than the deck and have rounded angles. Three segmental arches have projecting keystones. V-shaped cutwaters are stepped up to a projecting band at the base of a low parapet. Parapet has flat coping (part renewed in reconstituted stone) and terminates with square piers on L bank (with later stone walls attached). Later stone walls are also attached on R bank. On the upstream side is a tablet set into the parapet and inscribed: "This Bridge was built and finished at the expence [sic] of the Right Honourable Sir John Nicholl under the inspection of William [Whirlington?] Country Surveyor by Morgan Thomas of Laleston AD 1827".

Listed Grade II*, New Bridge is a fine example of an early C19 road bridge, its design similar to the Glan-Rhyd tramroad viaduct near Tondu.
