Pont Newydd (Southern) is a post-medieval or modern bridge located in Wales and protected by Cadw as a scheduled monument under reference DE099. The structure spans bedrock composed of Llandovery rocks, an undifferentiated sequence of mudstone, siltstone and sandstone formed during the Llandovery period of the Ordovician. These sedimentary strata were laid down in marine environments over 440 million years ago and now form a relatively resistant but weatherable foundation across much of south Wales.
The bridge's construction reflects the practical engineering demands of crossing terrain underlain by these softer Ordovician rocks, which are prone to gullying and erosion by watercourses. The designation of Pont Newydd (Southern) as a protected monument indicates its historical or architectural significance within the Welsh landscape, even though its exact date of construction and original purpose are not fully documented.
The site forms part of the broader heritage record of post-medieval bridge building in Wales, a period when improved communications and crossing points became increasingly important. The bridge's location upon Llandovery bedrock is typical of structures throughout the Welsh uplands, where such ancient sedimentary foundations present both challenges and opportunities for infrastructure development.
