Cardigan Bridge is a post-medieval bridge crossing the River Teifi in Cardigan, Pembrokeshire, Wales. The structure spans limestone bedrock of Ordovician age, formed over 450 million years ago when this region lay beneath a tropical sea. The river has cut its channel through these ancient strata, creating the valley that the bridge now traverses.
The bridge carries the principal route across the Teifi at this strategic point in the settlement, a river that has long been a significant natural boundary and communication route in South Wales. Its design and construction reflect the practical engineering requirements of its period, with the underlying Ordovician limestone providing a stable foundation for the masonry piers.
The monument is protected by Cadw, the Welsh Historic Monuments service, under reference CD003. This official designation recognises Cardigan Bridge's historical importance to the built heritage of Cardigan and the wider Pembrokeshire region, ensuring its preservation for future generations as a record of post-medieval engineering and the continuity of settlement patterns along the River Teifi.
