Hen Bont, Pont-Erwyd is a post-medieval and modern bridge located in Wales, protected by Cadw under reference CD006. The structure spans across terrain underlain by Llandovery rocks, a formation of mudstone, siltstone and sandstone deposited during the Llandovery period of the Ordovician era. This geology shaped both the landscape and the practical challenges of bridge construction at this crossing point.
The bridge represents the layered history of Welsh infrastructure development, with elements from both its post-medieval origins and later modifications reflecting changing techniques and materials. The Llandovery bedrock beneath provides a stable foundation despite the mixed composition of mudstone and siltstone, materials that can be prone to weathering when exposed. The presence of sandstone within the sequence would have offered harder building stone potentially quarried locally for the bridge's construction.
Hen Bont exemplifies the continuity of communication routes in rural Wales, where crossing points on watercourses required substantial investment in masonry and engineering. Its designation by Cadw recognises its significance as a structure that bridges (literally and historically) the post-medieval and modern periods of Welsh heritage, preserving evidence of how communities maintained essential connections across challenging terrain.
